What are you trying to do?
Pick a goal. We’ll show you the peptides in this library that address it, plus an honest label of whether the evidence is from research, community use, or a topical-only context. Click into any peptide for the full evidence-tiered profile, or add it straight to your stack from here.
Goals not listed (fertility, libido, mood, cognitive endurance, etc.) — the peptides in our current library don’t have strong evidence or established community use for those. Ask the AI on a specific peptide page if you have a particular question; it will be honest about what we know and don’t.
Weight management & metabolic health
The strongest-evidence corner of this library. The GLP-1 / GIP class has Tier 1 RCT data for both type 2 diabetes and chronic weight management.
Dual GIP/GLP-1 agonist. SURMOUNT-1 (n=2,539) showed 15–22% mean body weight reduction at 72 weeks. FDA-approved as Zepbound for chronic weight management.
GLP-1 agonist. STEP-1 showed 14.9% mean body weight reduction at 68 weeks. SELECT trial added a 20% reduction in major adverse cardiac events in the obesity + CVD population. FDA-approved as Wegovy.
GHRH analog approved for HIV-associated visceral fat. Off-label use targets visceral adipose reduction in non-HIV populations on the basis of the same mechanism.
Recovery & tissue repair
Animal data for tendon, ligament, gut, and muscle healing is consistent across many models. Published human RCTs are absent for most of these — read the evidence tier carefully.
Synthetic 15-amino-acid peptide derived from a gastric protein. Animal data is large and consistent; community uses it for tendons, ligaments, gut, and post-injury recovery. Tier 3.
Thymosin Beta-4 fragment. Animal evidence for cell migration and angiogenesis. Frequently stacked with BPC-157 in community recovery protocols. Tier 3 — and WADA-banned for competitive athletes.
Longevity & GH-axis
Peptides that amplify the body's natural pulsatile growth hormone release. Most have plausible mechanisms but limited human outcomes data — read the tiers carefully.
Selective GHRP — minimal cortisol or prolactin elevation, which is its main differentiator vs older GHRPs. Common pairing with CJC-1295 for synergistic GH release. Tier 3 for off-label longevity use.
GHRH analog. No-DAC form mimics natural pulses (multi-daily); with-DAC form sustains elevation (weekly). Almost always paired with a GHRP like ipamorelin. Tier 3.
Strongest evidence base of any GHRH analog (FDA-approved for HIV lipodystrophy). Off-label community use targets the same GH/IGF-1 axis effects.
Sleep
GH-axis peptides dosed at bedtime can deepen the natural overnight GH pulse, which several users report as deeper sleep. The literature on subjective sleep quality from these peptides is thin; community reporting is consistent enough to mention but not strong enough to claim as proven.
Bedtime ipamorelin (often paired with CJC-1295) is the dominant community sleep stack. Mechanistic basis: amplified overnight GH pulse, which some studies link to slow-wave sleep. Tier 3.
Same protocol shape as ipamorelin — bedtime, fasted. The two are typically co-administered. Tier 3.
Skin & hair
Topical applications dominate the evidence base here. Injectable / systemic claims for the same compounds are a separate evidence question and usually weaker.
Tier 2 for topical skin and wound applications — multiple human studies on collagen synthesis, wound healing, and cosmetic outcomes. Tier 3 for injectable systemic use; the topical evidence does not transfer.
Anti-inflammatory & gut
Peptides whose mechanisms touch inflammatory pathways. Animal evidence is generally cleaner than human; the gut indications for BPC-157 are some of the better-studied animal models.
Animal models suggest broad anti-inflammatory and gut-healing effects, including in IBD models, gastric ulcers, and post-NSAID gut damage. No published human RCTs.
Anti-inflammatory effects shown in topical wound-healing studies. Mechanistically promising; injectable systemic claims are not supported by transferable evidence.
