Peptide manufacturers are building factories for predicted upcoming excess production.

Samsung Biologics Is literally Buying UP Peptide factory companies !!!

Chinese Peptide maker Wuxi basically building factories in different regions to make local peptides outside of China, so that they can sell in local rules and regulations.

So BIG MONEY has spoken.

They are investing billions into peptides and that will become products in syringes with auto-injections cartridges !

So like it or NOT, big pharma made a serious bet and they rarely do those !

Look up peptide producing factories, they are all building new facories !

And then look up auto-injection cartridge companies !

They are building new factories to increase supply of those !

Once ready, there will be ads with brand names selling peptide injections !

This is actually a major problem. Whereas people invest time and money into solving other problems they just accept this and make it part of the social paradigm.

Like for example vote for biosciences for biohacking.

Vote in politicians that push for practices that can put it all on a fast track.

Donations and investments towards the goal.

Do your own research.

Build up your own

Elon Musk isn't the goal. It has to be towards biosciences, medicine.

**Abstract**

**Background**

Glycine serves as a critical substrate for glutathione synthesis and a critical modulator of redox homeostasis. However, whether plasma glycine is associated with biological aging, and the underlying interplay between oxidative stress, inflammation, and dietary context remains unclear.

**Methods**

We analyzed the UK Biobank data to investigate the association between plasma glycine and biological aging, primarily assessed by the Klemera-Doubal Method (KDM) residuals. Restricted cubic splines were used to assess the nonlinear relationships. Mediation analysis assessed the roles of inflammatory and oxidative stress markers. Interactive analysis was applied to explore the relationship between comprehensive dietary patterns and glycine-related aging.

**Results**

Higher plasma glycine was negatively associated with KDM residuals (β: −0.729, 95%CI: −0.815, −0.643). Mediation analysis demonstrated that the inverse glycine-aging association was partially explained by reduced systemic inflammation and modulation of redox biomarkers (mediation proportions: 3.9% to 25.6%). Exploratory in silico Gene Ontology (GO) analysis provided supportive evidence implicating oxidative stress and inflammatory responses in these pathways. Notably, we identified a sex-specific diet interaction, the inverse association between glycine and KDM residuals was attenuated in males consuming a pro-inflammatory and pro-oxidative diet (β: −0.757, 95%CI: −1.294, −0.220) compared to the anti-inflammatory and anti-oxidative diet group (β: −0.939, 95%CI: −1.402, −0.476) (*p* for interaction = 0.014). No such interaction was observed in females.

**Conclusion**

Plasma glycine negatively correlated with biological aging, partly through modulation of the redox-inflammatory axis. The male-specific vulnerability to pro-oxidative and pro-inflammatory diets highlights that glycine's efficacy is contingent upon a favorable nutritional context. These results support for precision interventions integrating glycine optimization with anti-inflammatory dietary patterns to extend healthy longevity.

THE ULTIMATE SCIENCE-BASED EXERCISE GUIDE TO LIVING LONGER, STAYING STRONGER, PROTECTING YOUR BRAIN, AND MAINTAINING A HEALTHY, FUNCTIONAL BODY FOR AS MANY YEARS AS POSSIBLE.

Physical exercise is one of the most powerful tools available for improving human healthspan. Regular movement supports cardiovascular fitness, muscle strength, bone density, metabolic health, brain function, mobility, and psychological well-being. Research consistently associates higher physical activity and cardiorespiratory fitness with lower risks of premature mortality. Exercise can improve insulin sensitivity, mitochondrial function, blood vessel health, and the body's capacity to maintain and repair tissues. Some forms of exercise also stimulate autophagy-related signaling and beneficial adaptations in skeletal muscle. However, no exercise has been proven to stop biological aging or guarantee immortality. The objective is to build physical resilience throughout life, reduce preventable disease, and preserve the ability to live independently. The best exercise program changes with age: babies need movement and exploration, children need active play, teenagers need fitness and strong bones, adults need aerobic and resistance training, and older people need strength, balance, and mobility. Here are ten essential stages of lifelong exercise for maximizing health and longevity.

BABIES (0–12 MONTHS): BUILD THE FOUNDATIONS OF MOVEMENT, MOTOR DEVELOPMENT, AND BRAIN HEALTH. The journey toward lifelong physical health begins before a child can even walk. Babies benefit from supervised tummy time, reaching for toys, grasping objects, rolling, stretching their arms and legs, crawling, turning their heads, and eventually pulling themselves into standing positions when developmentally ready. Tummy time helps strengthen the neck, shoulders, arms, and trunk while supporting motor development and head control. Reaching and grasping encourage hand-eye coordination, while crawling and floor exploration develop coordination and movement skills. The World Health Organization recommends that infants who are not yet mobile receive at least 30 minutes of tummy time distributed throughout the day while awake, beginning with short, supervised sessions appropriate to the baby's abilities. Safe floor play, interaction with caregivers, and opportunities to move naturally are more important than structured exercise programs. Never force babies to stand, walk, or perform movements before they are developmentally ready. Tummy time must always be supervised, and infants should be placed on their backs for sleep. At this age, exercise means exploration, healthy development, and building the foundations for a physically active childhood.

TODDLERS AND PRESCHOOL CHILDREN (1–4 YEARS): DEVELOP STRONG BONES, COORDINATION, BALANCE, AND A LOVE OF MOVEMENT. Early childhood is the perfect time to turn physical activity into a natural and enjoyable part of everyday life. Excellent activities include walking, running, dancing, climbing age-appropriate playground equipment, jumping, hopping, chasing bubbles, throwing and catching soft balls, playing hide-and-seek, obstacle courses, swimming with close supervision, riding tricycles, and exploring parks. These activities help improve balance, coordination, muscle development, cardiovascular fitness, spatial awareness, and confidence. Running and jumping provide weight-bearing stimulation that supports bone development, while dancing and ball games improve movement control. Children aged 1–2 should accumulate at least 180 minutes of physical activity of any intensity throughout the day. Children aged 3–4 should also accumulate at least 180 minutes, including at least 60 minutes of moderate-to-vigorous activity. These recommendations include play spread throughout the day, not three hours of intense training. Activities should be enjoyable, varied, safe, and developmentally appropriate. Avoid excessive sedentary time and provide adequate sleep for healthy growth and recovery. The goal is not to create young athletes through pressure. It is to help children discover that moving their bodies is one of life's most enjoyable and beneficial habits.

CHILDREN (5–9 YEARS): BUILD A STRONG HEART, HEALTHY BONES, AND LIFELONG FITNESS HABITS. Children should experience an enormous variety of enjoyable physical activities, including football, basketball, swimming, cycling, running, dancing, gymnastics, skipping rope, playground climbing, martial arts, tennis, badminton, hiking, and active outdoor games. Each activity develops different aspects of fitness. Running, cycling, and swimming strengthen cardiorespiratory endurance; jumping and skipping stimulate bone development; gymnastics and climbing support coordination and muscular strength; and team sports develop social skills, confidence, and cooperation. From age five, WHO guidance recommends an average of at least 60 minutes of moderate-to-vigorous physical activity daily across the week, predominantly aerobic, with vigorous activity and exercises strengthening muscles and bones on at least three days weekly. Games involving jumping, running, push-ups, climbing, and age-appropriate bodyweight movements can help meet these goals. Children should learn fundamental skills such as squatting, balancing, throwing, catching, landing safely, and changing direction. Activities should be adjusted to individual abilities, and rest, hydration, adequate nutrition, and sufficient sleep are essential. A physically active childhood builds fitness, confidence, movement skills, and habits that may support health for decades.

PRETEENS (10–12 YEARS): STRENGTHEN THE SKELETON, DEVELOP ATHLETIC SKILLS, AND IMPROVE CARDIOVASCULAR FITNESS. The years approaching adolescence provide an excellent opportunity to improve muscular coordination, bone development, cardiovascular endurance, and movement technique. Recommended activities include swimming, cycling, basketball, football, volleyball, running, tennis, martial arts, dance, gymnastics, hiking, jump rope, climbing, and supervised introductory resistance training. Bodyweight squats, lunges, wall or floor push-ups, assisted pull-ups, planks, and resistance-band exercises can build strength safely when proper technique, appropriate resistance, and supervision are provided. Weight-bearing activities such as jumping, hopping, running, and court sports provide beneficial mechanical loading for growing bones. Swimming and cycling are excellent for cardiovascular fitness, although they should be complemented by weight-bearing activities for skeletal health. Continue targeting an average of at least 60 minutes of moderate-to-vigorous activity each day, including vigorous and muscle- and bone-strengthening activities on at least three days weekly. Avoid emphasizing maximal lifts, physique obsession, excessive exercise volume, or restrictive dieting. Children develop at different rates, making individualized progression essential. Strong movement foundations established before adulthood can support healthier bones, muscles, and physical activity habits throughout life.

TEENAGERS (13–17 YEARS): BUILD CARDIORESPIRATORY FITNESS, MUSCLE STRENGTH, AND PEAK BONE DEVELOPMENT. Adolescence is a particularly important period for establishing lifelong exercise habits and accumulating bone mass. Teenagers can benefit from a comprehensive fitness program combining aerobic activity, resistance training, sport, and mobility work. Outstanding activities include jogging, cycling, swimming, brisk walking, football, basketball, volleyball, tennis, badminton, rowing, dancing, martial arts, hiking, and recreational athletics. Supervised strength training can include squats, lunges, push-ups, pull-ups, rows, hip hinges, resistance bands, and age-appropriate free weights or machines. Resistance exercise improves muscular strength, movement capacity, and bone-loading adaptations when performed with correct technique and sensible progression. Running, sprinting, jumping, and court sports provide vigorous cardiovascular and skeletal stimulation. Teenagers should average at least 60 minutes of moderate-to-vigorous activity per day, including activities strengthening muscles and bones on at least three days each week. Training should prioritize skill, gradual progression, recovery, sleep, and sufficient food intake, not extreme intensity or appearance-focused pressure. The ultimate goal is to enter adulthood with strong bones, healthy muscles, excellent movement skills, and a powerful foundation for cardiovascular fitness.

YOUNG ADULTS (18–29 YEARS): BUILD THE CARDIOVASCULAR AND MUSCULAR FOUNDATION FOR DECADES OF HEALTHY LIFE. Young adulthood is an excellent time to establish a sustainable training routine that improves VO₂ max, muscular strength, endurance, metabolic health, and functional fitness. Some of the most valuable exercises are brisk walking, cycling, jogging, running, swimming, rowing, hiking, stair climbing, dancing, and recreational sports. Combine them with resistance training involving squats, deadlifts or hip hinges, lunges, step-ups, presses, rows, pull-ups, and core-stability exercises. Aerobic exercise strengthens the cardiovascular system and can improve oxygen delivery and utilization, while resistance training helps build muscle and strengthens bones and connective tissues. HIIT, such as repeated brief efforts on a bicycle or rowing machine separated by recovery intervals, can efficiently improve cardiorespiratory fitness for appropriately prepared individuals. However, HIIT is optional, and regular moderate-intensity exercise is already highly beneficial. Adults should aim for 150–300 minutes of moderate aerobic activity or 75–150 minutes of vigorous activity weekly, alongside muscle-strengthening exercise at least twice weekly. Some people can benefit from progressing beyond these levels if recovery and health permit. The objective is to develop fitness that can be maintained for a lifetime, not to achieve temporary athletic performance at the expense of long-term health.

ADULTS (30–44 YEARS): PROTECT HEART HEALTH, MAINTAIN MUSCLE, AND REDUCE FUTURE CHRONIC DISEASE RISK. As work, family, and other responsibilities increase, exercise becomes especially important for maintaining health and preventing prolonged inactivity. An effective program combines brisk walking, cycling, jogging, swimming, rowing, hiking, elliptical training, and recreational sports with consistent resistance training. A practical approach is to distribute 150–300 minutes of moderate aerobic exercise throughout the week and perform two or three full-body strength sessions, adjusted to personal fitness and recovery. Strength exercises can include squats, split squats, hip hinges, rows, push-ups, chest presses, overhead presses, calf raises, loaded carries, and abdominal stabilization. Regular aerobic training supports blood pressure regulation, insulin sensitivity, and cardiovascular fitness. Resistance exercise helps preserve lean mass, improve strength, and support glucose regulation. Flexibility and mobility exercises for the hips, shoulders, ankles, and spine can complement training, while standing breaks and short walks can interrupt prolonged sitting. Cycling to work, taking the stairs, walking after meals, or exercising with friends can increase activity without requiring an entirely separate fitness lifestyle. The longevity advantage comes from consistency: combining cardiovascular endurance, muscular strength, and daily movement year after year.

MIDDLE-AGED ADULTS (45–64 YEARS): DEFEND CARDIORESPIRATORY FITNESS, MUSCLE MASS, METABOLIC HEALTH, AND FUNCTIONAL CAPACITY. Midlife is an important period for protecting against declines in muscle strength, aerobic fitness, and physical function. Walking, cycling, swimming, hiking, rowing, elliptical exercise, dancing, and other aerobic activities can improve endurance and support cardiovascular health. Resistance training is particularly important because progressive strength exercise helps preserve muscle mass and physical capacity. Include squats or chair squats, step-ups, lunges, machine leg presses, hip hinges, resistance-band rows, cable exercises, chest presses, calf raises, and carrying movements. Aim for at least two weekly strength sessions and 150–300 minutes of moderate aerobic activity, or the equivalent in vigorous exercise, as tolerated. For people who are already well conditioned, carefully progressed vigorous training may help maintain VO₂ max, a strong marker associated with lower mortality risk. Tennis, badminton, dancing, and other enjoyable activities can also provide cardiovascular conditioning, coordination, and social engagement. Balance drills, mobility work, and appropriate recovery become increasingly useful. People with significant cardiovascular symptoms, uncontrolled conditions, or major limitations should obtain appropriate medical assessment before initiating strenuous exercise. Midlife training is an investment in the ability to remain strong, metabolically healthy, physically capable, and independent in later decades.

OLDER ADULTS (65–79 YEARS): FIGHT SARCOPENIA, PROTECT THE BRAIN, IMPROVE BALANCE, AND PRESERVE INDEPENDENCE. Exercise becomes an essential tool for preserving physical function as people grow older. Age-related reductions in strength and muscle mass can contribute to sarcopenia, frailty, impaired mobility, and increased fall risk. The best exercise strategy combines aerobic training, progressive resistance exercise, balance activities, and functional movements. Excellent choices include brisk walking, stationary cycling, swimming, water aerobics, Nordic walking, dancing, hiking on suitable terrain, chair squats, sit-to-stands, step-ups, resistance bands, machine exercises, light-to-moderate free weights, and supervised strength training. Tai Chi, supported single-leg stands, tandem walking, heel-to-toe walking, and controlled direction changes can improve balance and postural control. Walking and cycling support cardiovascular endurance, while resistance training helps preserve muscle strength and everyday abilities such as climbing stairs and rising from a chair. WHO recommends 150–300 minutes of moderate aerobic activity weekly or an equivalent vigorous amount, muscle-strengthening activity on at least two days, and multicomponent exercise emphasizing strength and functional balance on at least three days each week. Activities should be scaled to health, fitness, and fall risk. The real victory in older adulthood is not simply surviving longer; it is remaining capable of walking, moving, thinking, traveling, and living independently.

ADVANCED AGE (80–100+ YEARS): PRESERVE MOBILITY, PREVENT FRAILTY, AND KEEP THE BODY FUNCTIONAL FOR AS LONG AS POSSIBLE. Even at very advanced ages, physical exercise can remain beneficial when adapted to individual abilities, medical conditions, and safety needs. Frailty and advanced age are not automatic reasons to abandon exercise. Appropriate activities may include short supervised walks, supported standing, seated marching, chair sit-to-stands, heel raises, gentle step-ups, resistance-band rows, light hand-weight exercises, supported balance practice, gentle dancing, water-based activity when safe, and individualized rehabilitation exercises. For people with limited mobility, seated leg extensions, ankle movements, gentle upper-body resistance exercises, and assisted transfers can provide meaningful opportunities for movement. Resistance training can help improve strength and everyday functioning, while balance and functional exercise can reduce fall risk when appropriately prescribed. Walking maintains mobility and endurance, and mobility exercises can help preserve comfortable movement. The emphasis should be on manageable sessions, regularity, hydration, proper nutrition, adequate recovery, and gradual progression rather than intense workouts. Exercise plans should account for osteoporosis, severe frailty, cardiovascular disease, cognitive impairment, and other conditions, ideally with professional guidance when necessary. Even small improvements in walking ability or chair-rise strength can be life-changing. Our mission is to help people remain physically capable, independent, and engaged with life for as many years as possible. Exercise cannot currently guarantee biological immortality, but it is one of our strongest evidence-based tools for protecting health while longevity science advances. — Dr. Georgios Andreas Ioannou

Hi immortalists! As I get some questions on fasting and fasting ketosis specifically, I want to highlight that ketones are not just an alternative energy source. They are signaling molecules that actively change how your body works during fasting. The liver converts roughly 20-30% of free fatty acids into ketones to help fuel the brain when glucose is low, but here’s what else ketones do

• Suppress inflammation: Beta-hydroxybutyrate inhibits the NLRP3 inflammasome - a key driver of chronic inflammation
• Regulate gene expression: Ketones act as HDAC inhibitors, influencing which genes are turned on or off, including stress resistance and longevity-related pathways
• Increase cellular stress resistance: They upregulate FOXO and Nrf2 pathways, improving antioxidant defenses and resilience to damage
• Improve mitochondrial function: More efficient energy production with potentially lower oxidative stress
• Support brain function: Ketones increase BDNF and provide a stable fuel source, supporting cognition and neuroprotection
• Reduce oxidative stress: Lower ROS production compared to high-glucose metabolism states

And the most efficient way to raise ketones is... fasting. I am attaching my ketone data from a 10-day water fast - ketones crossed 5 mmol/L in about 56 hours and stayed in the 5-8 mmol/L range for most of the fast.

So, fasting is not just about weight or fat loss. It’s a systemic metabolic change that impacts inflammation, brain function, and cellular stress responses. If you’ve track ketones during keto or fasting, share your data. It will be interesting to compare results!
