You've probably seen peptides mentioned everywhere lately and thought — what actually are these things? Good news: they're not as complicated as the forums make them sound. We cover 34 of them right here, break down what the research shows each one does, and point you to verified sources. No jargon required.
Quick heads up before we dive in. Everything on this site is sold for research purposes. These compounds aren't FDA-approved for human use (with a few exceptions we'll note). Nothing here is medical advice — always consult a licensed physician. We just make the research easier to navigate.
Pick the research area closest to your focus. We'll break down how these compounds work, what the studies show, and where to source them.
Here's the simple version: fat loss peptides either tell your brain you're not hungry, or tell your body to burn more fat on its own. That's it.
Retatrutide is the appetite suppression route — it mimics the hormones your gut releases after a big meal, so your brain thinks you're full longer. It's the same mechanism as Ozempic, just hitting more receptors at once. The Phase 2 trial numbers were genuinely shocking — 24% body weight loss on average.
Tesamorelin works differently. It signals your pituitary to release more of your own growth hormone, which specifically targets the stubborn visceral fat around your organs. No appetite suppression — it just changes where your body stores and burns fat. FDA-approved, which is rare for this space.
AOD-9604 is the stripped-down version of growth hormone — just the fat-burning fragment, without the downsides of full HGH. A good entry point if you want something cleaner and more targeted.
Think of healing peptides as turning up the volume on your body's repair signals. Your body already knows how to heal — these just accelerate the process by increasing blood flow to damaged tissue and cranking up the growth factors that rebuild it.
BPC-157 is the one everyone starts with, and for good reason — it's the most researched healing peptide out there with over 100 studies behind it. Tendons, ligaments, muscle, gut lining — it's been studied on all of it, consistently.
TB-500 is the systemic partner. BPC-157 tends to work near where you inject it. TB-500 works body-wide, wherever you're hurt. A lot of people run them together for that reason — you get local and full-body coverage at the same time.
GHK-Cu (copper peptide) is more about skin, collagen, and soft tissue — it's actually used topically too. If your goal is skin repair or wound healing alongside deeper recovery, it's worth looking at.
Longevity peptides are targeting something specific: the biological clock, not just the symptoms of aging. Your cells age partly because the caps on the ends of your chromosomes (telomeres) get shorter every time a cell divides. When they're too short, the cell stops working properly. Epithalon activates the enzyme that rebuilds those caps.
MOTS-c goes after your mitochondria — the tiny power plants inside every cell that become less efficient as you age. When your mitochondria work better, your metabolism works better, your insulin sensitivity improves, and your cells just... run cleaner. It's been called a "mitochondrial exercise mimetic" because it activates some of the same pathways as a workout.
NAD+ is the most well-known one in this space. It's a coenzyme your body uses for energy production and DNA repair, and your levels drop significantly after your 30s. Topping it back up is one of the most evidence-backed things you can do for longevity right now.
Two pretty different things live in this category, so let's split them.
Semax and Selank are the nootropics — both developed in Russia, both prescription drugs there. Semax boosts BDNF, which is basically fertilizer for your neurons. More BDNF means better focus, faster learning, and more resilience against stress. Selank is the calmer sibling — it takes the edge off anxiety without making you foggy or dependent on it. They stack well together.
PT-141 is a different animal entirely. It works on sexual function, but through your brain rather than through blood flow (that's how Viagra works). The practical difference: it works for both men and women, and it works even when vascular issues are the underlying cause. It's FDA-approved as Vyleesi — the only FDA-approved treatment for female sexual dysfunction that's a peptide.
