Quick take
American Peptides posts lot-coded certificates for most of its catalog and publishes a Shreveport address and phone number. The homepage names Bioviridian as its lab, but the COA page and product pages do not, and refunds are limited to replacing damaged or wrong items. It also sells liquid sprays and dissolving strips alongside vials, which falls outside research-use-only supply.
The seven checks
| Independent lab testing | Partly | The homepage names Bioviridian, but the COA page and product pages name no lab and the report checked could not confirm it. |
|---|---|---|
| Batch-specific COAs | Yes | The COA page lists lot-coded files for each size of 51 products, though a few products show only safety data sheets. |
| Identity confirmed by mass spec | Partly | Mass spec is claimed and the file checked carries mass spec ion labels, but observed and expected mass values could not be read. |
| Research-use labeling | No | Sells liquid sprays and dissolving strips alongside vials, which doesn't fit research-use-only supply. |
| Age and use confirmation | Yes | Visitors confirm they are 21 or older and accept research-use terms on entry, and checkout asks for a researcher certification. |
| Clear shipping and refund terms | Yes | A combined shipping and refund page covers dispatch times, lost parcels, the 72-hour damage window and cancellations. |
| Business transparency | Yes | A Shreveport street address, phone number, support email, ticket form and terms page are published. |
American Peptides is a US online store that sells freeze-dried research peptides and ships from Shreveport, Louisiana, where its footer lists a street address. It publishes a phone number and a support email, and the whole site sits behind a 21+ research-use gate.
We looked at the homepage, the COA page, a vial product page, a spray and a strip listing, one certificate file, the learning hub, and the combined shipping and refund policy. The lot paperwork is broad, but the lab is named in only one place, and the catalog mixes vials with sprays and strips.
Who American Peptides is and what the catalog covers
The catalog is split into single research peptides, an in-house AP series, blends, bioregulators, liquid sprays, dissolving strips, bundles and branded apparel. The site gives two counts, about 74 compounds in one place and 80 listings in another. Vial starting prices seen ran from about $40 to $105, and several products come in two or three strengths.
No company history, founding year or staff details are given. The site does not publish a legal company name beyond the brand.
Lot-coded COAs and the testing behind them
A central COA page lists 51 products, each with one or more lot-coded files, such as a separate lot for each BPC-157 strength. Product pages link to the same files, and many products also carry a safety data sheet. A couple of products show only a safety data sheet, and one lot code appears on two different files.
The homepage says every batch is verified by Bioviridian for HPLC-MS purity, MALDI identity and endotoxin. The COA page and the product page checked do not name any lab, and the certificate file opened could not be read beyond its mass spec ion labels, so the lab name could not be confirmed on the report itself.
The spray and strip listings reuse the COAs of matching vial products, so those reports do not describe the finished liquid or film. Endotoxin and sterility testing are claimed in a banner but were not seen on a report.
Labeling, sprays and strips, and purchase checks
Visitors must confirm they are 21 or older and accept research-use terms before entering, and checkout asks buyers to certify they are a qualified researcher or institution. Vial pages state that products are for in vitro research only, give no use instructions, and list storage conditions.
Alongside vials, the store sells ten liquid sprays in metered bottles and three dissolving strip products, one of which contains non-peptide compounds. These self-administration formats do not fit research-use-only supply, even though their pages also carry research-use notices and give no directions. Some of these listings have storage notes that do not match the format.
Shipping, replacements and support
Orders ship within the US only, from Louisiana, and are usually dispatched within 24 to 48 business hours, with a same-day cutoff that the site states in two different time zones. Costs are set at checkout for standard or expedited service, and shipping is free above $300. Carriers, transit times and cold packs are not named in the policy.
All sales are final. Damaged or wrong items must be reported within 72 hours of delivery with the order number and photos, and verified items are replaced at no cost. Parcels confirmed lost in transit are investigated with the carrier. Payment methods are not listed on the pages checked. Support works by email, phone and ticket, with a stated one-business-day reply.
Verdict: what to check before ordering
American Peptides suits US labs that want lot-coded paperwork for a wide catalog and a reachable Louisiana contact. It is a weaker fit for labs that need the testing lab named on each report or a refund option beyond replacement.
Before ordering, ask support which lab issued the report for your lot, match the lot code on the vial to its file, and confirm the result with that lab.

Questions
Is American Peptides legit?
American Peptides publishes a Shreveport address, phone number, research-use gate and lot-coded COAs for most products, but it names its lab only on the homepage.

What is the American Peptides refund policy?
All sales are final. Damaged or wrong items reported within 72 hours with photos are replaced at no cost, and lost parcels are investigated with the carrier.
