Peptide science, decoded.
Curious about a peptide you saw online? Start here. We read the studies so you can see what’s actually been shown in people, what’s still just a promising idea, and where the internet gets ahead of the evidence.
Human studies kept separate from animal research. Every claim linked to the paper behind it. Written to be understood — whether you’re just curious or reviewing it for work.
Explore by research interest
You don't need to know peptide names. Start with what you want to understand.
Metabolism
GLP-1, GIP & glucagon research — the incretin compounds.
Skin & Appearance
Copper and signal peptides studied for skin and tissue.
Recovery
Tissue-repair research — the most hyped, most debated space.
Focus & Mood
Neuroactive peptides and the nootropic evidence question.
Energy & Longevity
Mitochondrial-derived peptides and the exercise-mimetic claim.
Hormones & Performance
Growth-hormone pathway and hormonal signaling research.
Sexual Health
Melanocortin-pathway research and what the trials showed.

Trial phases, evidence levels, and how to read a study.
What people are researching now
Each card gives you the verdict in seconds — the evidence level, the claim gap, the bottom line.
Retatrutide
MetabolismPhase 3 trials back the headline weight numbers — but it's still investigational, with long-term safety data not yet complete.
GHK-Cu
Skin & AppearanceReal topical skin and wound research exists — but many online claims (especially injectable anti-aging) run well past the evidence.
BPC-157
RecoveryExtensive animal findings, scientifically interesting — but robust controlled human evidence remains very limited. Confidence online far exceeds the data.
Three things, done well

What the internet says vs. what the evidence says
On every page. This is the whole point.
"BPC-157 heals every injury — tendons, joints, gut, nervous system. A miracle recovery peptide."
Most support comes from animal and laboratory studies. Robust controlled human evidence remains very limited, and effective human applications, long-term safety, and consistent formulation are still open questions.
