Frequently asked questions

It means the product is sold as a laboratory research chemical - not as a drug, supplement, or cosmetic - and is not approved for human or veterinary use. Two things buyers often get wrong about it:

First, the label is not a legal shield for sellers. Under the FDA's intended-use doctrine (21 CFR §201.128), regulators judge a product by how it is marketed and used, not by what the label says. In its warning letters of 24 August 2026 to online peptide sellers, the FDA pointed to exactly the surrounding content - benefit claims, dosing information and calculators, and reconstitution supplies sold alongside vials - as evidence of intended human use.

Second, that is why this site publishes no dosing, protocol, or usage content of any kind, and why a seller whose pages are full of it is showing you their regulatory risk profile, not their expertise.

No. The compounds covered on this site - MOTS-c, Semax, KPV, Epithalon and blends containing them - are not FDA-approved for any human use. Most have never been through FDA review. Any site implying otherwise is misdescribing the products it sells.

Three different answers, because "legal" covers three different activities - and as of October 2026 they point in different directions:

• Sold as research chemicals: the compounds are sold openly in the research-chemical channel under "research use only" labeling. The channel is policed through intended use - market a product for human use and the FDA treats it as an unapproved drug whatever the label says (21 CFR §201.128). That doctrine is what the August 2026 warning letters enforced.
• Compounded by pharmacies: not available for the compounds covered here. None of MOTS-c, Semax, KPV, or Epithalon is on the 503A Bulks List, and inclusion would require FDA rulemaking.
• Approved for human use: none of them, for any use.

State rules can add restrictions on top of the federal position described here.

The same three-way answer as the other compounds covered here. BPC-157 is not FDA-approved for any human use. It is sold in the research-chemical channel under "research use only" labeling, which the FDA polices through intended use. And it is not on the 503A Bulks List: BPC-157 was considered for inclusion on the 503A Bulks List at the FDA Pharmacy Compounding Advisory Committee's July 2026 meeting; committee recommendations are non-binding advice to the FDA, and inclusion would require FDA rulemaking.

On 23-24 July 2026, the FDA's Pharmacy Compounding Advisory Committee considered seven bulk drug substances for the 503A Bulks List, the list of substances licensed compounding pharmacies may use: BPC-157, TB-500, KPV, MOTS-c, Emideltide (DSIP), Semax and Epitalon. Committee recommendations are non-binding advice to the FDA; inclusion would require FDA rulemaking.

What the meeting changed: the committee's recommendations are non-binding advice to the FDA, and inclusion on the Bulks List would require FDA rulemaking.

Nobody outside the FDA knows, and the agency has published no date. What has to happen is rulemaking: a compound joins the 503A Bulks List through a published FDA rule, and until a final rule takes effect, the legal position does not change - an advisory recommendation starts that process; it does not finish it. Anyone quoting a legalization date is guessing.

A certificate of analysis is the lab report for a specific batch of product. A meaningful COA has four properties: it names the batch or lot it covers; it comes from a third-party laboratory rather than the seller; it reports identity and purity testing by HPLC and mass spectrometry; and its results match the lot number on the vial you receive. A generic COA reused across products, with no lot number and no method stated, verifies very little. For blends such as GLOW and KLOW, each named component should be verified - see the KPV page.

Testing, warehousing, and an unstandardized market. Tracked on 24 October 2026 (PeptidePrices): the lowest 10 mg MOTS-c listing was $15.31 across 252 tracked vendors; the lowest 10 mg BPC-157 listing was $19.16 across 243 tracked vendors; Selank, the most commoditised compound here, had a lowest tracked 10 mg listing of $17.97 across 200 tracked vendors. The full tracked table is on the price-comparison page; source: PeptidePrices.

MOTS-c is sold as a 10 mg vial. Price tracking (PeptidePrices, checked 24 October 2026) shows the lowest 10 mg listing at $15.31 across 252 tracked vendors. The full tracked table is on the price-comparison page. Prices in this market change weekly, so check the date on any figure you rely on.

Deliberately, and for documented reasons. Retatrutide is an unapproved investigational drug; its developer, Eli Lilly, sued six sellers on 12 August 2026 and has filed further suits since - search demand for it is enormous, and it is still not a product a responsible publisher builds a catalogue on. SS-31 (elamipretide) received FDA accelerated approval on 19 September 2025 as the prescription drug Forzinity for Barth syndrome, which makes research-channel versions of it the clearest enforcement target in the catalogue. DSIP (emideltide) was among the compounds considered at the July 2026 advisory committee meeting and is not FDA-approved. High search volume is not the same thing as a sound product.

Mostly lyophilized (freeze-dried) vials - the standard format across the catalogue. Two compounds covered here are also commonly listed in nasal-format bottles: Semax and Epithalon. A few compounds exist in capsule form in the compounding channel. A nasal bottle and a vial of the same compound are not interchangeable products, and they should not be price-compared as if they were; the formats differ in their research contexts, and vendor copy that blurs the distinction is hiding a real one. This site describes formats; it does not publish usage information for any of them.
