A healing compound originally found in stomach juice. It's one of the most versatile peptides out there -- great for repairing damaged tissue, healing the gut lining, and calming down inflammation. Arguably the most well-studied healing peptide available.

A fragment of a natural immune protein that helps your body repair tissue, reduce inflammation, and grow new blood vessels. It works throughout your whole body, making it excellent for recovering from injuries of all kinds.

A naturally occurring copper-linked peptide your body already makes. It's a powerhouse for skin rejuvenation, wound healing, and anti-aging -- it boosts collagen production and actually flips on anti-aging genes throughout your body.

A long-lasting growth hormone booster. The DAC (Drug Affinity Complex) part keeps it active in your body much longer than similar peptides, giving you a steady, sustained rise in growth hormone for better muscle growth, fat loss, and recovery.

A shorter-acting growth hormone booster that releases GH in natural pulses, mimicking what your body does on its own. Without the DAC attachment, it clears faster, so it's usually paired with another GH peptide for a stronger combined effect.

One of the cleanest ways to boost your growth hormone. It tells your pituitary to release more GH without messing with cortisol (your stress hormone) or prolactin, which means fewer side effects than other GH peptides.

A growth hormone booster that also seriously increases your appetite by mimicking ghrelin (your hunger hormone). Good for bulking phases or anyone who struggles to eat enough calories.

A stronger growth hormone booster than GHRP-6, with a more moderate appetite increase. It raises both GH and IGF-1 (another important growth signal), though it can slightly bump cortisol and prolactin levels.

The most powerful GH-releasing peptide available -- it produces the biggest growth hormone spike of any peptide in this class. It also has heart-protective benefits. The downside is your body builds tolerance to it faster than other options.

Works through your nervous system to boost sexual desire and arousal -- it acts on the brain, not the blood vessels (unlike Viagra). It's actually FDA-approved under the name Vyleesi for low sex drive in women.

A longevity peptide based on a compound from the pineal gland. It turns on the enzyme that protects the caps on your DNA (telomerase) and restores healthy melatonin production for better sleep. Russian studies showed a 25-33% lifespan increase in animals and reduced death rates in elderly patients. A 162-patient trial found no serious side effects, and sleep improvements typically show up within 1-2 weeks.

Derived from the thymus (a key immune gland that shrinks as you age). It helps restore immune function and has shown life-extending properties in clinical studies by essentially waking up your aging immune system.

A 28-amino-acid immune powerhouse originally from thymus tissue. It strengthens both your fast-response and long-term immune systems: helps immune cells (T-cells) mature, boosts your natural killer cells, and balances your immune response so it's neither too weak nor too aggressive. Tested in over 3,000 patients in clinical trials, approved in 35+ countries, and used for hepatitis B/C, HIV support, cancer treatment support, and serious infections. No serious side effects linked to the peptide.

A Russian-developed anxiety-reducing peptide that works on your brain's natural calming system (GABA), serotonin levels, and your body's built-in painkillers (enkephalins). It eases anxiety without making you drowsy, and there's no risk of dependence or withdrawal. It also gives your immune system a boost. Decades of clinical use in Russia with a great safety track record.

A brain-boosting peptide developed at the Russian Academy of Sciences in the 1980s. It boosts your brain's main growth and repair signal (BDNF) by 1.5-3x, increases nerve growth factor, promotes the creation of new brain cells in the memory center, and improves blood flow to the brain. Used clinically in Russia for decades for stroke recovery, traumatic brain injury, ADHD, and cognitive decline. You'll typically notice effects within 5-10 days.

A souped-up version of Semax with chemical modifications that make it more potent and easier for your body to absorb. Gives a stronger boost to brain growth and repair signals (BDNF) with longer-lasting cognitive benefits.

An extremely powerful brain peptide -- it's millions of times more potent than your brain's own growth signal (BDNF) at helping brain cells form new connections. One of the strongest nootropics available for memory and cognitive enhancement.

An oral pill that tells your body to release more growth hormone and IGF-1 (a key growth signal). It's well-known for improving deep sleep, increasing appetite, and gradually building muscle while burning fat over time.

A signaling peptide that sits upstream of your body's hormone production chain. It nudges your brain to naturally produce more testosterone and reproductive hormones without shutting down your own production -- think of it as gently turning up the dial rather than replacing anything.

A lab-made version of the hormone your brain uses to tell your pituitary gland to release LH and FSH (the hormones that drive testosterone production and fertility). Commonly used to keep the testes functioning during testosterone replacement therapy.

A brain peptide that helps you get more deep sleep (the restorative delta-wave kind). It normalizes disrupted sleep patterns and reduces stress, and unlike many sleep aids, you won't feel groggy the next morning.

A synthetic peptide that stimulates your skin to produce more melanin (giving you a tan without UV exposure), suppresses appetite, and boosts libido. Basically a tanning, fat-loss, and sexual function peptide rolled into one.

Your body's own natural antibiotic peptide. It fights a wide range of bacteria, viruses, and fungi, helps break up bacterial biofilms (stubborn colonies that resist treatment), and supports wound healing while keeping your immune response in check.

A topical anti-wrinkle peptide that works by reducing the nerve signals that make your facial muscles contract (similar idea to Botox, but applied as a cream). It smooths out expression lines over time with regular use.

A longevity peptide that selectively triggers "zombie cells" (old, damaged cells that refuse to die and cause inflammation) to self-destruct, while leaving healthy cells alone. One of the most precise tools available for clearing out these aging-related problem cells.

A peptide engineered to go straight to your cells' power plants (mitochondria). It repairs the inner walls of your mitochondria, boosting energy production (ATP) by 20-40% and reducing harmful free radicals by 30-50%. Tested in over 500 patients in advanced clinical trials. Think of it as the foundation peptide -- by giving your cells more energy, it makes every other peptide work better too.

A small piece of human growth hormone (specifically the fat-burning part, amino acids 176-191). It tells your body to break down fat and stop storing new fat, but without the muscle-growing or blood sugar effects of full growth hormone.

An FDA-approved growth hormone booster specifically studied for reducing deep belly fat (visceral fat). It's one of the most clinically validated peptides for improving body composition, with strong research behind it.

A small molecule that blocks an enzyme (NNMT) which normally slows down your metabolism. By blocking it, your cells produce more NAD+ (a key energy molecule) and burn more energy overall. Promotes fat loss and may help fix metabolic issues.

A peptide discovered in 2015 that's actually encoded in your mitochondrial DNA (which is unusual). It flips your body's metabolic master switch (AMPK), making your cells more sensitive to insulin, better at burning fat, and essentially mimicking the effects of exercise at a cellular level. When stacked with SS-31, NAD+, and Retatrutide, it creates a four-way metabolic boost through four different pathways.

A protective peptide produced by your mitochondria. It shields cells from damage caused by oxidative stress, helps brain cells survive, and protects the heart. Think of it as your cells' built-in bodyguard.

A brain-boosting peptide derived from a natural nerve-protecting protein (PEDF). It strengthens memory formation and sharpens cognitive performance through a unique mechanism that's different from other popular nootropics like Semax.

A brain-repair peptide blend derived from pig brain tissue that contains natural nerve-growth factors. It's used clinically to help recover from strokes, traumatic brain injuries, and degenerative brain conditions. Backed by a strong body of research.

A tiny three-amino-acid peptide with serious anti-inflammatory power. It's especially effective for gut inflammation, making it a go-to for conditions like IBD and other inflammatory gut issues. Also helps calm down whole-body inflammation.

A peptide that tightens up the seals between your gut lining cells, directly addressing "leaky gut" (where stuff slips through gaps it shouldn't). Originally developed for celiac disease, but useful for anyone dealing with gut barrier problems or autoimmune conditions.

A compound with anti-inflammatory and cartilage-protecting properties. It shields your joints, thins blood slightly, and calms inflammation. Clinically used for bladder conditions (interstitial cystitis) and joint health.

A modified version of IGF-1 (a powerful growth signal) that lasts longer in your body. What makes it special is it can actually create new muscle cells (not just make existing ones bigger), making it one of the most potent muscle-building peptides out there.

Blocks myostatin -- the protein your body uses to cap how big your muscles can get. By blocking that brake signal, your muscles can grow past their natural genetic ceiling. A seriously powerful muscle-building peptide.

The most popular growth hormone combo, pre-mixed in one vial for convenience. It pairs two peptides that work through different pathways, giving you a strong, clean growth hormone release with fewer side effects. Considered the gold standard starter stack for anyone looking to optimize their growth hormone levels.

The ultimate healing combo in one vial. Combines BPC-157's targeted gut and tissue repair with TB-500's whole-body healing abilities. Together they amplify each other's anti-inflammatory and regenerative effects.

The active ingredient in Ozempic and Wegovy. It mimics a natural gut hormone (GLP-1) that tells your brain you're full and slows down how fast food leaves your stomach. Extremely effective for weight loss and improving metabolic health overall.

The active ingredient in Mounjaro and Zepbound. It hits two gut hormone receptors at once (GLP-1 and GIP), making it even more effective than semaglutide for weight loss and blood sugar control. Currently one of the most powerful weight management drugs available.

A long-lasting version of a growth factor your body naturally produces when muscles are damaged during exercise. It wakes up dormant muscle stem cells (satellite cells), telling them to repair and grow the muscle. Best used right after training.

A SARM (selective androgen receptor modulator) that gives you about 66% of testosterone's muscle-building effects but only 27% of its masculinizing side effects. A milder option for building lean mass with fewer hormonal downsides.

A critical molecule every cell needs to produce energy and repair DNA. Your levels drop by 50% by age 50 and 80% by age 80. It activates your longevity genes (sirtuins), powers your DNA repair crew (PARP enzymes), and is essential for your mitochondria to make energy. Injecting it bypasses the absorption problems you get with oral supplements. When combined with SS-31, it's considered one of the most powerful peptide combos available.

A tiny three-amino-acid peptide from the Khavinson bioregulator family that works at the gene level -- it enters your cells, interacts with DNA, and switches on genes that produce brain-protective proteins. It reduces brain cell death, clears out damaging free radicals in the brain, and enhances neuronal repair. You'll typically see effects within 1-2 weeks, with peak results at weeks 4-6.

A bioregulator peptide that targets your cardiovascular system. It supports blood vessel health, strengthens vessel walls, and promotes healthy circulation. Part of the Khavinson bioregulator family from Russian longevity research.

One of the smallest active peptides known -- just two amino acids. It supports your thymus gland (immune HQ) and helps your immune cells properly develop and specialize. A simple but effective immune system tune-up.

A four-amino-acid bioregulator that specifically targets the brain's outer layer (cerebral cortex), where your thinking happens. It supports cognitive function, helps your brain form new connections, and may slow age-related mental decline.

One of the most commonly prescribed growth hormone peptides. It's a copy of the first 29 amino acids of your body's natural growth hormone-releasing hormone, so it triggers your pituitary to release GH in natural pulses -- the way your body is supposed to do it.

A next-generation weight loss drug from Eli Lilly that hits three gut hormone receptors at once (GLP-1, GIP, and glucagon) -- currently in Phase 2/3 clinical trials. At low doses (2 mg), it optimizes metabolism and protects the brain WITHOUT major weight loss. At higher doses (8-12 mg), it can produce up to 24% body weight loss. The GLP-1 pathway also provides significant brain protection, with positive results seen in 175+ disease models.

The fat-burning slice of human growth hormone (amino acids 176-191). It targets fat cells to break them down without the muscle-growth or blood sugar-raising effects you'd get from full HGH. Very similar to AOD-9604.

The "bonding hormone" -- your brain naturally releases it during hugs, intimacy, and social connection. It promotes feelings of trust, empathy, and closeness while also reducing anxiety, lowering stress hormones (cortisol), and helping you regulate emotions.

Derived from the blood-building hormone EPO, but modified so it activates your body's built-in repair system without increasing red blood cell production. It protects nerves, shields tissues from damage, and fights inflammation. Studied for nerve damage (small fiber neuropathy) and the inflammatory condition sarcoidosis.

Originally developed for Parkinson's and Alzheimer's, researchers discovered it causes major weight loss as a side effect. It works by boosting three brain chemicals at once -- serotonin, dopamine, and norepinephrine -- which crushes appetite and revs up metabolism.

An "exercise in a pill" compound that activates the same molecular pathways your body turns on during endurance training. It improves how your cells' power plants (mitochondria) function, increases fat burning, and boosts muscle endurance -- without you needing to hit the gym (though you still should).

A shortened version of IGF-1 that's 10x more powerful at the receptor but clears your body very quickly. That short lifespan is actually the point -- you inject it directly into the muscle you want to grow, and it acts locally before disappearing. Ideal for targeted muscle growth.

A souped-up version of Selank with chemical modifications that make it more stable and easier for your body to use. It delivers stronger anxiety-reducing and immune-boosting effects than regular Selank.

A dual-action weight loss peptide from Boehringer Ingelheim that targets two gut hormone receptors (GLP-1 and glucagon). The glucagon part gives it an extra edge for reducing liver fat, making it especially promising for fatty liver disease (MASH) alongside obesity.

Another dual GLP-1/glucagon receptor drug, this one from Innovent Biologics. Works similarly to survodutide with impressive weight loss and metabolic health results. Already approved in China for obesity treatment.

A hormone that initially spikes your LH and FSH (the signals that drive testosterone production), then causes them to taper off. Commonly used for post-cycle therapy (PCT) to kickstart your body's natural hormone production after a steroid or SARM cycle. The single-dose PCT approach is popular.

An aggressive, experimental fat-destruction peptide. It works by cutting off blood supply to fat cells, starving them until they die. This is a targeted approach -- it goes after fat tissue specifically -- but it's still very much in the experimental stage.

The active ingredient in Saxenda and Victoza -- one of the first GLP-1 drugs for weight loss. Not as strong as semaglutide, but it has years of clinical data behind it and a well-established safety profile. Requires daily injections since it doesn't last as long in your body.

A hormone from your thymus gland that needs zinc to work. It helps your immune cells develop properly, keeps your immune system balanced, and supports thymus regeneration. Your body naturally makes less of it as you age.

A unique brain booster that enhances your dopamine system, promotes the growth of new nerve branches, and may even help regenerate dopamine-producing brain cells. Unlike most cognitive enhancers, it works through a completely different mechanism. Important: you need to avoid sun and UV exposure while using it.
