An evidence-first peptide reference
Straight-talk peptide reference for adults who read the studies.
Every dose, mechanism, and side effect traced back to a clinical trial or manufacturer protocol — including the parts where the evidence is honestly thin.
What this is
Sourced from clinical trials. Not Reddit. Not blogs.
Most peptide content online is either a hype-y supplier blog or forum anecdote dressed up as research. Neither tells you what the trials actually show — including the parts where the evidence is thin.
Every dosing range here cites a clinical trial, manufacturer protocol, or published guideline. Every mechanism description points back to primary literature. When the answer is “we don’t really know,” it says that.

What’s a peptide?
A short chain of amino acids — basically a tiny protein. Your body makes them all the time: insulin, oxytocin, growth hormone fragments. Synthetic peptides mimic or modify those natural signaling molecules.
Some are FDA-approved drugs (Wegovy, Mounjaro). Most others are research compounds with varying levels of evidence behind them.
