Research, on record.
Structured records of published peptide research — design, population, main findings, and limitations, each with a direct link to its source. Every record is verified against its publication before it appears here. These are reading aids for the research itself, not conclusions about effectiveness or safety.
How we label evidence.
Controlled experiments in humans where participants were randomized to groups — the strongest design for isolating a compound's own effect, though still limited by duration, population, and blinding quality.
Human studies without randomization — cohort, case-control, open-label, and single-arm studies. Useful signals, but more open to bias and confounding.
Experiments in animals. Findings often do not translate to humans, and results should never be read as expected human outcomes.
Cell cultures, tissues, and biochemical assays. These establish plausible mechanisms but say nothing about whole-body effects in living humans.
We have not identified qualifying published research on this question yet. Absence of studies is not evidence of absence of effect — it is uncertainty.
These labels describe the kind of research available for a question — they are not a measure of effectiveness or safety, and a larger number of studies does not by itself make a conclusion stronger. Where publications duplicate or reanalyze the same trial, the record says so.
