At a glance
- Current core SKUs post lot-matched MZ Biolabs HPLC-UV-MS certificates.
- Ashraf 2024 measured their then-semaglutide at 7.70% purity versus 99% claimed.
- Semaglutide is gone from the August 2026 catalog. That paper still counts.
- Ownership is opaque: virtual Las Vegas suite, no named legal entity.
- Prefer Ascension for indexed per-lot COAs and the ENHANCED 50% code.
Most 2024 roundups still describe Biotech Peptides as "COA on request." That line is stale. The product pages now ship lot-numbered PDFs from MZ Biolabs. The more interesting question is whether those sheets are enough, given what an academic lab measured in a vial this vendor used to sell.
This review is biotechpeptides.com. It is not Limitless Biotech (our oral partner), not Biotech Peptides Canada, and not the Brazil clone at biotechpeptides.com.br.
Bottom line up front: Long-running US research-use catalog, public MZ Biolabs HPLC-UV-MS lots on current BPC-157 and related SKUs, and a documented 2024 independent failure on the semaglutide they no longer list. Not a scam storefront. Not a first-choice vendor. Open the current lot PDF if you buy; for a repeat protocol, Ascension Peptides with code ENHANCED is the sharper default.
What Biotech Peptides is
The live contact page lists Biotech Peptides at 8275 S Eastern Ave Suite 200, Las Vegas, NV 89123, with support@biotechpeptides.com and a 619-453-0156 number. Suite 200 at that address is an executive/virtual-office building, not a walk-in synthesis plant. Terms are governed by California law. The domain has sat on biotechpeptides.com since 31 January 2020, WHOIS-privacy at a Luxembourg registrar. Homepage copy says they have been synthesizing peptides since 2019.
No officer or legal entity is named on About, Contact, or Privacy. "Dr. Usman" is a content byline, not a disclosed owner. Age rules conflict (terms say 18+, the age gate says 21+). Shipping copy conflicts too (12 pm vs 1 pm PST cutoff; a refunds page promises 30 days while Terms say all sales final). Those are sloppy ops, not a smoking gun.
The August 2026 catalog is 89 lyophilized and topical SKUs: BPC-157, TB-500, GLOW/KLOW-style blends, GH secretagogues, bioregulators, cosmetic powders. Semaglutide, tirzepatide, and retatrutide are not in the current product sitemap. Oral capsules and nasal sprays are not in the catalog.
Sticker prices we checked: BPC-157 5/10 mg at $52 / $92; TB-500 10 mg at $124; BPC+TB 10 mg blend at $115; CJC-1295 + Ipamorelin 10 mg at $81; Tesamorelin 10 mg on sale at $73. Quantity breaks are 5% at 5 vials and 10% at 10. Free USPS Priority over $200. Lost or damaged parcels replaced.
Stay on the .com. The Canada domain has its own Trustpilot and is treated in secondary sources as a copy. Do not merge them.
The testing story in 2026
This is no longer a request-only shop. Product pages expose a lot field and a PDF. We opened several July 2026 certificates:
| Lot | Compound | HPLC-UV | Identity |
|---|---|---|---|
| 3140013 | BPC-157 5 mg | 99.94% | MS 1418.75 vs 1418.70 Da |
| 3140012 | BPC-157 10 mg | 99.88% | MS 1418.76 vs 1418.70 Da |
| 3140022 | DSIP 5 mg | 99.02% | MS 848.34 vs 848.33 Da |
| 3141018 | Ipamorelin + CJC no-DAC | 99.94% combined | both masses confirmed |
The standard sheet is MZ Biolabs, Tucson, AZ, analyst Ken Pendarvis, method HPLC-UV-MS, client line "Biotech Peptides," analysis date 15 July 2026. Purity plus identity. No endotoxin, no sterility, no fill weight. Salts and sugars are excluded from the impurity math, which is normal for that template and easy to miss if you only read the headline percent.
A Semax PDF on the site uses a different, unnamed-lab template (HPLC 99.1%, assay 114.5%, endotoxin "conforms"). Treat that as manufacturer-style paperwork, not MZ.
Finnrick has a Biotech Peptides vendor page and zero published customer tests as of August 2026. A listing is not a grade. We found no Janoshik certificates for this shop.
Why a pretty chromatogram is not the whole job: commercial research peptides have shipped as the wrong sequence (De Spiegeleer et al., Anal Biochem 2008, PMID 18342612), as undeclared mannitol at 20 to 43% by weight that HPLC/UV can miss (Choules et al., JPBA 2020, PMID 31671336), and as libraries contaminated with a common HCMV peptide that produced false-positive T-cell reads (Currier et al., Clin Vaccine Immunol 2008, PMID 18077621). Identity, quantity, and contaminants are three different questions. Our COA explainer and lab-tests library exist so you can see what a lot-matched public certificate actually looks like.
The Ashraf paper, which they do not get to outrun
In 2024, Ashraf and colleagues bought finished "semaglutide" vials from online sellers without a prescription and assayed them. One of those sellers was Biotech Peptides, listed then as a US / San Diego shop, $113 for a 3 mg GLP-1c vial (Ashraf et al., JMIR 2024, PMID 39509151).
Their lab, not the vendor COA, measured:
- Label: 3 mg at 99% purity
- Found: 3.86 mg of peptide in a 50.1 mg powder cake
- Measured purity: 7.70 ± 0.28%
- Endotoxin present
- Visual packaging failed most of the FIP checklist
That is not a Reddit anecdote. It is a peer-reviewed purchase of this vendor's then-semaglutide. The SKU is gone from the 2026 sitemap. The paper is not. Do not write as if the current BPC-157 lots were in that study. Do not write as if the study is irrelevant because the homepage now says RUO.
A March 2024 Reddit thread also caught a then-current BPC-157 COA at 98.2% while the vial said >99%. That specific lot is superseded by the July 2026 99.88 to 99.94% MZ sheets. The pattern (label ahead of the PDF) is the thing to remember.
Reputation and clones
We could not load Trustpilot in this research pass (CloudFront 403). Competitor blogs quote ~4.8 from ~330 reviews. We are not repeating an unverified star count. PeptideMind's August 2026 mix sits around 4.0 from 312 aggregated comments: same-day ship and replacement vials on the plus side; clone-site confusion and "wish they named the lab" on the minus side. The lab is now named on the MZ PDFs. Reviews.io is three old template-scam posts and is not a dataset.
Reddit volume is modest. One June 2023 report said a Matrixyl order arrived in a vial labeled Core Peptides, which is a white-label/fulfillment signal, not proof of shared ownership. "USA synthesized" remains an official claim, not something we independently verified.
No FDA warning letter turned up under the brand name. We do not have a legal entity name to search. Unknown is the honest word.
Biotech Peptides vs Ascension
| Check | Biotech Peptides | Ascension Peptides |
|---|---|---|
| COA before purchase | Yes, lot PDF on the product page | Yes, plus a library we index at lab-tests |
| Named lab | MZ Biolabs on current standard sheets | Janoshik, lot-matched images |
| HPLC + identity | HPLC-UV-MS | HPLC + MS |
| Endotoxin / fill | Usually absent on MZ sheets | Call the actual lot, not the homepage |
| Independent fail on file | Ashraf 7.70% vs 99% on old sema | None of that class on file here |
| Current GLP-1 SKUs | Not in the Aug 2026 catalog | Research vials with public lots |
| Ownership | Virtual NV suite, unnamed | See the full audit |
| BPC-157 10 mg sticker | $92 | Compare after code ENHANCED (50% off) |
Biotech is a documented mid-tier US RUO shop that now posts real MZ lot PDFs. That is better than a "email us for a COA" storefront. It is not enough to beat a partner whose lots we already index, and it is disqualifying to forget the 7.7% paper. For the wider field, use the best legit peptide vendors list.
Who this vendor is for
Buy from Biotech Peptides if you want a long-running US card-checkout catalog, you will open the current MZ PDF for that lot, and you are looking at a recovery or GH-axis vial such as BPC-157 rather than a coded GLP-1. Use the BPC-157 dosage chart for the protocol math.
Skip them if you were about to treat a 2023 semaglutide marketing page as current, if you need endotoxin or fill-weight on the certificate, or if a search result sent you to the Canada or Brazil clone.
For a research plan that spans several compounds and several months, Ascension Peptides is the sharper default at 50% off with code ENHANCED. Cross-check lots in the lab-tests library before either cart.
