AOD-9604 is a fragment of growth hormone designed to target fat without growth effects. It burned fat in obese mice; human weight-loss trials did not beat placebo.
BPC-157 is a 15-amino-acid peptide based on a protein found in stomach juice. In rat studies it sped up healing of tendons, ligaments, muscle and the gut lining, making it one of the most talked-about recovery peptides.
No single sequence or 3D structure applies
Cerebrolysin is a mix of brain-derived peptides that support nerve cells. It is used in several countries and has been tested in stroke and brain-injury trials.
CJC-1295 copies the natural signal that triggers growth-hormone release, built to last much longer. Early human trials showed growth hormone and IGF-1 stayed higher for days after a single dose.
Epitalon is a four-amino-acid peptide researched for sleep and longevity. Rodent studies linked it to melatonin changes and longer lifespan, making it a favorite in the anti-aging world.
Follistatin 344 is a binding protein that blocks myostatin, the body’s natural brake on muscle growth. In animal research, raising follistatin led to noticeably more muscle.
GHK-Cu is a tiny copper-binding peptide found in many skin and hair products. Research links it to collagen, firmer-looking skin, wound repair and hair growth.
GHRP-2 uses the ghrelin signal to release growth hormone. Human studies show it raises both growth hormone and appetite.
No molecular model shown until its sequence is checked
GHRP-6 releases growth hormone through the ghrelin signal and is known for a strong boost in hunger. It is discussed for building size and recovery.
Retatrutide, shown here as GLP3, targets three appetite and metabolism signals at once. In a phase 2 trial, people lost about 24% of their body weight on average over 48 weeks, and it is now in late-stage trials.
Glutathione is the body’s main built-in antioxidant, a three-amino-acid peptide. Small trials found brighter, more even skin tone, and it is popular for skin and recovery.
No molecular model shown until its sequence is checked
Hexarelin is one of the strongest growth-hormone triggers in its class. Rat studies also found it protected heart tissue.
Humanin is a protective signal made by mitochondria. Mouse studies link it to healthier metabolism, and higher levels are associated with healthy aging in people.
No molecular model shown until its sequence is checked
IGF-1 LR3 is a longer-lasting version of IGF-1, one of the body’s main growth signals. Lab research uses it for its strong effect on muscle and cell growth.
Ipamorelin uses the ghrelin signal to release growth hormone, with little effect on stress hormones in animal studies. People look it up for sleep, recovery and body composition.
Kisspeptin-10 is a short form of the natural signal that starts the body’s sex-hormone chain. In human studies it briefly raised LH and testosterone, and it is used in fertility and hormone research.
KPV is a three-amino-acid piece of alpha-MSH, a natural calming signal. Mouse studies found it settled gut inflammation, and researchers are exploring it for skin as well.
LL-37 is a germ-fighting peptide your own body makes. Animal studies show it kills bacteria and speeds wound healing, and a small human trial found faster healing of leg ulcers.
Melanotan II switches on the skin’s pigment signal and a brain desire signal. Small human studies showed tanning and improved erections, which is why it is known as the tanning peptide.
MOTS-c is a tiny peptide made by mitochondria, the energy centers inside cells. In mice it boosted exercise capacity and insulin sensitivity, which is why people call it an exercise signal.
A peptide backbone would be inaccurate
NAD+ is a molecule every cell needs to turn food into energy, and levels drop with age. Small human studies show boosters raise NAD levels, and it sits at the center of the longevity conversation.
No molecular model shown until its sequence is checked
P21 is a lab-designed peptide built from a brain growth factor. In mice it improved memory and the growth of new nerve cells.
No molecular model shown until its sequence is checked
Pinealon is a three-amino-acid peptide aimed at brain cells. Rat and lab studies found it protected nerve cells, and it is popular with people interested in memory and healthy aging.
PT-141, or bremelanotide, works on desire signals in the brain rather than blood flow. A prescription form, Vyleesi, is approved for low sexual desire in some premenopausal women.
Selank is a seven-amino-acid peptide related to tuftsin, an immune peptide. Russian studies found calming effects in anxiety, and people look it up for stress and a clearer head.
Semaglutide is the GLP-1 medicine behind Wegovy and Ozempic. It turns down appetite and steadies blood sugar, with about 15% average weight loss in its main weight trial.
Semax is a seven-amino-acid peptide that raises BDNF, a growth factor for brain cells. It is used in Russia for stroke recovery and attention, and draws interest for focus and memory.
Sermorelin is a short copy of the body’s own growth-hormone release signal. It was once FDA-approved to test and treat growth hormone deficiency in children, and is still discussed for healthy aging.
SS-31, also called elamipretide, protects the inner wall of mitochondria, the cell’s power plants. It has been tested in trials for rare mitochondrial diseases and restored muscle function in old mice.
TB-500 is based on thymosin beta-4, a protein that helps cells move to where repair is needed. Animal studies link it to faster wound healing and tissue recovery, and it is a staple of recovery conversations.
No molecular model shown until its sequence is checked
Tesamorelin signals the body to release more of its own growth hormone. It is approved as Egrifta to reduce belly fat in adults with HIV-related fat buildup, and is studied for body composition.
No single sequence or 3D structure applies
Thymalin is a thymus-derived peptide mix that supports immune cells. It has been used in Russia, is studied mostly by one research group, and is discussed for immune support with age.
No molecular model shown until its sequence is checked
Thymogen is a two-amino-acid thymus peptide used in Russia to support immune function.
Thymosin alpha-1 is an immune-signaling peptide that helps train and activate immune cells. It is approved in several countries as Zadaxin and is studied across a range of immune conditions.
Tirzepatide works on two gut-hormone signals, GLP-1 and GIP, that control appetite and blood sugar. It is approved as Zepbound and Mounjaro, with about 21% average weight loss at the top dose in its main trial.
