The Peptide Guide
An overview of the peptide categories people research most, written in plain language and reviewed on a rolling basis. This is educational content, not medical advice — see the full disclaimer.
Weight Loss & Metabolic
Very High interestThe most-searched category on the platform
GLP-1 and dual-agonist compounds that influence appetite regulation and glucose metabolism. Includes both prescription therapeutics and research-use analogs.
Clinical dosing reference — FDA-approved only
Shown only for prescription drugs with an FDA label. This describes how these medications are typically prescribed, not a recommendation for you specifically — your prescriber sets and adjusts your actual dose.
Semaglutide (Wegovy)
- Titration
- Weekly subcutaneous injection, starting at 0.25 mg. Dose is increased roughly every 4 weeks — 0.25 mg → 0.5 mg → 1 mg → 1.7 mg → 2.4 mg — over about 16 weeks, to reduce GI side effects.
- Maintenance dose
- 2.4 mg once weekly (1.7 mg is an FDA-approved alternative maintenance dose for patients who don't tolerate 2.4 mg).
- Trial results
- In the STEP 1 trial (68 weeks), participants on semaglutide plus lifestyle intervention lost a mean of 14.9% of body weight, vs. 2.4% on placebo.
Tirzepatide (Zepbound)
- Titration
- Weekly subcutaneous injection, starting at 2.5 mg (a treatment-initiation dose, not a maintenance dose). After 4 weeks, increased to 5 mg, then optionally in 2.5 mg increments every 4+ weeks up to a maximum of 15 mg.
- Maintenance dose
- 5 mg, 10 mg, or 15 mg once weekly — many patients stay at 5 mg or 10 mg rather than titrating to the maximum.
- Trial results
- In the SURMOUNT-1 trial (72 weeks), participants on the 15 mg dose lost a mean of 20.9% of body weight, vs. 3.1% on placebo.
Other compounds in this category (e.g. Retatrutide, AOD-9604) have no FDA-approved human dosing to cite — see the note below.
Compounds without a clinical dosing box above (e.g. BPC-157, TB-500, Ipamorelin, PT-141, Epithalon) have no FDA-approved human dosing to cite — they’re sold as research chemicals, and any dosing numbers you’d find elsewhere online come from anecdotal or gray-market sources, not established clinical research. We won’t publish those as if they were. Use “Recent studies” above to pull live results from PubMed (the NIH’s public database of biomedical literature) — that shows what’s actually been published, which is not the same as evidence that a use is safe or effective in humans.

High interestSleep, recovery, and body composition
Peptides studied for their effect on the body's own growth hormone pulses, as an alternative to exogenous HGH.
