Peptides side by side, scored on what has actually been shown.
For every pair we count the human trials, name the species behind each finding, and set the risks and legal status next to each other. No sellers, no dosing, every source linked.

What the badges mean
Each column of a comparison is scored with the strongest kind of study behind it. More dots means stronger evidence in people.
- Lab
Only tested on cells.
- Animal
Tested in animals, not yet in people.
- Human
Small or uncontrolled studies in people.
- RCT
Placebo-controlled trials in people.
- Approved
A regulator approved it for a named use.
How we compare
- Outcome by outcomeWe never crown an overall winner. For each outcome we show the strongest evidence each peptide has.
- Counted, not claimedTrial numbers, sample sizes and species come straight from PubMed, ClinicalTrials.gov and the FDA.
- No one pays us to pickWe link no sellers, take no vendor money and give no dosing instructions.
