Score breakdown
Strengths & weaknesses
- US-based synthesis and lyophilization (claims peptides are produced and freeze-dried in-house in the United States)
- Substantial catalog — 89 product pages spanning healing, growth, longevity, and metabolic peptides plus topical cosmetic peptides (no GLP-1s)
- Per-batch COAs on 84 of 89 product pages (read 12 October 2026); at least 58 follow the MZ Biolabs (Tucson, AZ) file pattern, and the two we opened name the client, lot, HPLC-UV-MS method and a QR authenticity code
- Same-day shipping if orders are placed by 1pm PST
- Free replacement on damaged or lost packages, plus a stated 30-day refund guarantee (physical returns are not accepted)
- Explicit 503A non-compliance disclaimer (research-grade only — honest framing)
- Affiliate program available
- Lab coverage is uneven. About 26 older SKUs carry a watermarked Biotech Peptides template certificate that names no testing lab (the AOD-9604 certificate, lot 3140006, is dated 10 March 2026 and reports purity 99.0% and an assay of 87.7%), while the newer certificates are MZ Biolabs reports. Five product pages (three topicals plus Chonluten and Follistatin 344) show no certificate. We did not scan the MZ Biolabs QR codes or find a public MZ Biolabs lookup, so no certificate is verified against the lab's own records
- Testing claims are not consistent across the site: the homepage says every batch is verified by a third-party lab with results posted on the website, while the About page still describes an in-house analytical lab. The newer MZ Biolabs certificates are third-party; for the template certificates we cannot say who ran the test
- No GLP-1s (Retatrutide / Tirzepatide / Semaglutide) — so cross-vendor comparison on the headline GLP-1 cluster is not possible against this vendor
- Physical returns are not accepted (the shipping page cites degradation and handling), although the refunds page states a 30-day refund guarantee and the shipping page promises a free replacement for damaged or lost packages
- Lookalike sites use the brand name: biotechpeptides.ca and biotechpeptidescanada.ca carry Trustpilot scam reports (payment by Interac e-Transfer, no product delivered), and one reviewer says the real company confirmed in writing that it is not affiliated. Only biotechpeptides.com is the domain audited here
- Scored on public records only; we have placed no test order

FROM PUBLISHED POLICY AND USER REPORTSAudit notes
FROM THE BENCHWhat we read
For this preview profile we synthesized the vendor's public catalog (88 products fetched at the time of audit, 13 tracked-compound matches), their about-page and shipping-policy disclosures, and the structure of their product pages — specifically looking for whether a Certificate of Analysis is published per-batch or aggregated on a public route. In October 2026 we re-read every product page in the shop's product sitemap (89 URLs), the refunds, shipping and contact pages, and opened three certificates in full (BPC-157 10mg, Tesamorelin 10mg and AOD-9604 5mg). We did not place a test order.
Why BioTech Peptides matters in 2026
BioTech Peptides is a long-running US-based research-peptide vendor with a catalog that spans most of the non-GLP-1 mainstream — BPC-157, TB-500, GHK-Cu, MOTS-c, Tesamorelin, NAD+, AOD-9604, plus a wider set of blends and less-common compounds. Their about-page positions them as in-house synthesizers (a claim we have not verified) with explicit 503A non-compliance — a more transparent framing than vendors who blur the regulatory line.
The catalog is one of the deeper research-grade offerings we have indexed on the price comparison, particularly on the longevity and growth clusters where most US vendors thin out. NAD+ at 100mg / 250mg / 500mg sizes is a notable point — only one other vendor we audit lists NAD+ at all.
What is still open
- COA verification. The certificates exist (see the section below), but we have not confirmed any of them against MZ Biolabs' own records: we did not scan the QR codes and did not find a public MZ Biolabs lookup. A buyer can check that the lot on a certificate matches the lot on the vial received, and scan the certificate's QR code to see where it resolves.
- Template certificates. About 26 older SKUs carry a Biotech Peptides watermarked certificate that names no lab. Vendor-issued documents are a weaker evidence class than a named third-party lab's report, and the certificate does not say who ran those tests.
- Shipping reliability. "Same-day shipping if ordered by 1pm PST" is the stated policy. We have no measured shipping data; a buyer can compare the dispatch date in the tracking record with that cutoff.
- Customer-service depth. As of 12 October 2026 we found no organic Reddit buyer reports for this vendor. The ranking lists that mention it still describe testing as in-house with certificates on request, which no longer matches the product pages, and some are posted by competitors. The Trustpilot page for the domain shows as removed, so there is no live review profile to read.
COAs on the product pages (read 12 October 2026)
We read all 89 product pages in the shop's product sitemap and looked for a downloadable certificate.
| Group | Product pages |
|---|---|
| Pages read | 89 |
| With a downloadable COA | 84 |
| MZ Biolabs file pattern (at least) | 58 |
| Template certificate, no lab named (about) | 26 |
| No certificate shown | 5 |
The 58 and 26 are counts of file names, not of certificates read. We opened three in full. The BPC-157 10mg and Tesamorelin 10mg certificates are MZ Biolabs reports (2102 N Country Club Rd, Tucson, AZ) naming Biotech Peptides as client, with lot number, HPLC-UV-MS method, a QR authenticity code and an analyst signature: BPC-157 10mg, lot 3140012, analysed 15 July 2026, 99.88% purity; Tesamorelin 10mg, lot 3140092, analysed 15 July 2026, 99.95% purity. The AOD-9604 5mg certificate is a Biotech Peptides watermarked template, lot 3140006, report date 10 March 2026, purity 99.0% and an assay of 87.7% against a stated specification of 80 to 120%, and it names no testing lab.
The /coas/ address on the shop is a blog article (a KLOW blend research piece dated 29 August 2026), not a certificate library. Certificates are attached product by product.
How BioTech Peptides compares on price
We walk the catalog daily and compare per-mg cost across all six audited vendors at /peptides-index. Highlights at the time of this preview:
- NAD+ at 500mg ($179, $0.36/mg) — cheapest per-mg NAD+ across the audit set. Only one other vendor (Ascension) lists NAD+ at all, at $0.12/mg on a 500mg vial.
- Tesamorelin 5mg ($38, $7.60/mg) — lowest per-mg tesamorelin in our index. Swiss Chems' 2mg vial is $13.97/mg.
- GHK-Cu 200mg ($186, $0.93/mg) — competitive with Limitless Life ($146.99 at 200mg, $0.73/mg) but cheaper than 50mg tier across all vendors.
- BPC-157 5mg at $52 sits between Particle Peptides ($27.83) and the upper tier (Pure Rawz $68.27); not market-leading but not premium either.
Lookalike domains and regulatory notes
Two sites trade on the brand name. Trustpilot pages for biotechpeptides.ca and biotechpeptidescanada.ca contain several scam reports describing payment by Interac e-Transfer and no product delivered, and one reviewer says the real company confirmed in writing that the .ca site is fraudulent and not affiliated. We have audited only biotechpeptides.com.
Separately, the Colombian health regulator INVIMA published an alert on 18 August 2026 calling products sold under a "Biotech Peptides" brand fraudulent because they have no Colombian sanitary registration. The alert names no website, and its list includes compounds (retatrutide, cagrilintide) that biotechpeptides.com does not sell, so we do not attribute it to this shop and apply no deduction. We found no FDA warning letter naming the shop as of 12 October 2026.
FAQ
Is BioTech Peptides legit? Public signals lean positive: a domain registered in January 2020, a published Las Vegas address and phone number, per-batch COAs on most product pages (many from MZ Biolabs), and no FDA warning letter or court filing naming the shop that we found as of 12 October 2026. Against that: no first-hand order, no certificate verified against the lab's own records, no independent re-tests (Finnrick lists none), and lookalike sites that use the name. This is a public-data preview, not a first-hand audit.
What does BioTech Peptides ship to the US? US-domestic shipping is the primary channel. We have not placed an order, so we have no transit time of our own; check the shop's shipping page for its current estimate.
Does BioTech publish COAs? Yes, on the product pages: 84 of 89 carry a downloadable certificate as of 12 October 2026. At least 58 follow the MZ Biolabs file-name pattern (the two we opened are MZ Biolabs reports with lot numbers and a July 2026 analysis date); about 26 older SKUs carry a Biotech Peptides template certificate with no lab named. We have not verified any certificate against the lab's own records.
What compounds does BioTech specialize in? Healing, growth-hormone-secretagogue and longevity peptides - BPC-157, TB-500, GHK-Cu, MOTS-c, Tesamorelin, NAD+, AOD-9604, CJC-1295/Ipamorelin and Sermorelin blends - plus topical cosmetic peptides. The catalog has no retatrutide, tirzepatide or semaglutide as of 12 October 2026.
What is the refund policy? The refunds page states a 30-day refund guarantee, but the shop does not accept physical returns. The shipping page promises a free replacement for damaged or lost packages.
Is biotechpeptides.ca the same company? No. biotechpeptides.ca and biotechpeptidescanada.ca are lookalike sites with Trustpilot scam reports (payment by Interac e-Transfer, no product delivered), and one reviewer says the real company confirmed in writing that it is not affiliated. The shop audited here is biotechpeptides.com.
