Weight lossSee how 15 peptides compare for weight loss. Find approved options, trial results, timelines, costs, access, and where the evidence stops.15 compounds covered Muscle growthCompare six peptides sold for muscle growth. Most studies measured hormones; a 16-week hexarelin study found no significant change in lean mass.6 compounds covered SkinCompare GHK-Cu, KPV and LL-37 for skin. Find out what creams, wound studies and animal tests showed, and why an injection is a different question.3 compounds covered Healing and recoveryCompare four peptides sold for healing and recovery. Separate animal findings and small human reports from trials that measured wound healing.4 compounds covered SleepCompare five peptides sold for sleep. DSIP has small human sleep studies; the other records mainly track hormones and body-clock signals.5 compounds covered Anxiety and depressionSelank has small human studies for anxiety, but the study summaries omit the dose. Compare the findings with Semax and BPC-157 and see the limits.2 compounds covered LongevityCompare six compounds sold for longevity. See what their studies measured, how long they ran, and why changing a marker does not prove a longer life.6 compounds covered Sex driveCompare PT-141 and kisspeptin-10 for sex drive. See who Vyleesi is approved for, what hormone studies found, and which uses lack good evidence.2 compounds covered Immune supportCompare three peptides sold for immune support. See what studies in sick patients found, and why those results may not apply to healthy adults.3 compounds covered TestosteroneCompare four peptides used for testosterone support. See what small studies found, what they did not test, and why the route and dose matter.4 compounds covered

Which compounds people take for which purpose

Each filled cell links a compound to a goal covered on this site. Its label distinguishes an approved use, a trial, a human study or reported use. 23 of the 50 pairings are based only on reported use, not proven results. A dash means the pairing is not included here.

FDA-approved — FDA-approved for this.: FDA approved a named product for this purpose.
Approved abroad — Approved outside the U.S..: A regulator outside the United States approved it for this purpose; FDA has not.
In trials — Being tested for this in trials.: A registered human trial is testing it for this purpose; that is not an approval.
Studied — Measured in a human study.: A human study measured something in this goal, without this being an approved purpose.
Reported — Reported use only.: This pairing is based on reported use. The available sources do not show a benefit for this purpose.

How to read the evidence

Each guide separates what people use from what studies in people measured. Reported use alone does not establish a benefit. Open a guide to see who was studied, what researchers measured and what remains unknown.

A compound can appear under more than one goal. Evidence for one use does not prove it works for another. The labels apply to each compound and goal together; they are not rankings or recommendations.

Where to go next

What peptides are, in plain English

The short definition, common forms and why different peptides cannot be judged as one group.

The skin table, basis by basis

Compare why people use each compound with what human studies have actually measured for skin.

Which testosterone claims have a trial

A hormone change is not a replacement-treatment result — see which popular claims still have no human evidence.

What is established for weight loss

For weight loss, 12 of 15 compounds have human evidence and 3 rely on reported use alone.

Anxiety and depression: the page beside the pitch

The Selank abstracts report outcomes but omit the dose.

Which sexual function claims have a trial

Kisspeptin results depend on the study population — see which popular claims still have no human evidence.
