The only peptide guide that gives every compound a transparent Clarity Score for safety & evidence, and keeps FDA-approved drugs and unregulated "research" chemicals in two clearly separated lanes. The real $/mg and the actual science — no hype.
Real prescription drugs (Ozempic, Mounjaro, Egrifta, Vyleesi…). The approved version belongs under clinician supervision — so we point you to licensed telehealth, not a gray-market vial.
Unregulated gray-market chemicals (BPC-157, TB-500, GHK-Cu…) plus a few only in trials. May be impure or mislabeled. We grade them honestly and link the science.
Research use only — no medical, dosing, or efficacy claims. Compounds are unregulated/investigational except where marked FDA-approved; approved drugs are obtained only through licensed telehealth, never a gray-market vial.
Pick a goal or a lane. Rows stay grouped into FDA-approved, investigational, and research-only, each carrying its Clarity Score, vendor trust tier, and COA status.

Every compound gets a 0–100 Clarity Score built from public, verifiable inputs — never a paid placement. Higher = more regulated, better human evidence, and real lab documentation. The score is payment-blind — FDA-approved drugs top it because they're the only regulated, human-trial-backed options, the same reason they're the only lane we route to licensed telehealth. That referral is disclosed and never moves a score.
FDA-approved scores highest; investigational in the middle; unapproved "research only" lowest. Linked to FDA.gov / ClinicalTrials.gov.
Strong human trials beat mixed/early data, which beat animal-only/preclinical. Linked to PubMed.

A "stack" is several compounds bought and grouped together because sellers and users claim they act along the same pathway. Below is what each is marketed for — not what it's proven to do. None of these combinations are FDA-approved as a stack, none are studied together in humans, and combining unregulated research chemicals multiplies the unknowns. Research use only — education, not medical advice, dosing, or any promise of an effect.
10 of our 18 tracked vendors stock MOTS-C, SS-31 and NAD+. Lowest in-stock sticker shown for each; vial sizes differ, so this is a shopping list, not a $/mg comparison. ⚑ = unrated, verify COAs.

Cheapest to assemble: Ion Peptide (~$131, though its NAD+ size isn't listed). Best documented value: Peptira — all three at clean 10 / 10 / 500 mg tiers (~$157) with per-product COAs. The 8 other tracked vendors carry MOTS-C and NAD+ but not SS-31.
Only one vendor pre-mixes MOTS-C and NAD+ in a single vial. The others are themed bundles. No vendor sells all three (MOTS-C + SS-31 + NAD+) in one product.
Prices captured 2026-06-26 from public vendor listings and may have changed. Shop links are affiliate links for research-use-only products; we may earn a commission, which never affects a Clarity Score. Nothing here is medical advice, a recommendation, or a dosing protocol.
No. BPC-157 has no FDA approval for human use and is sold only as a research chemical. The FDA has flagged it; most evidence is from animal studies.
Same molecule in name only. The approved drug is regulated and pharmacy-dispensed; gray-market "research" semaglutide is unregulated and may be impure or mislabeled. The approved version should be used under clinician supervision — which is why we route you to licensed telehealth.
A transparent 0–100: up to 40 for regulatory status, 30 for strength of human evidence, and 30 for the share of listings with a named-lab Certificate of Analysis. The full breakdown is shown on every compound page. Sponsorships never change a score.
A Certificate of Analysis — a batch lab report showing purity and identity. Strongest = batch-specific, from a named third-party lab, with a chromatogram and a matching lot number.
Most research peptides are legal to sell and possess for research purposes in the US, but are not FDA-approved for human use and are labeled "for research only."
