Is Sports Technology Labs legit?
On PeptideTrust's 10-criterion transparency scorecard, Sports Technology Labs scores 80/100 with 95% evidence coverage. That measures how openly it documents third-party testing, not the quality or safety of any product.
Is Sports Technology Labs a scam?
We make no fraud claim either way — PeptideTrust scores documentary transparency, not criminality. Sports Technology Labs scores 80/100 with 95% evidence coverage, and the table below links to exactly what we could and couldn't verify. Thin transparency is a reason for caution, not proof of a scam; a high score is not a guarantee of product quality.
Does Sports Technology Labs do independent third-party testing?
That is exactly what our scorecard measures. Sports Technology Labs has 9 of 10 weighted criteria verified (95% coverage); each row in the table below links to the third-party certificate, the named lab and the date we checked. Read the evidence rather than trusting a badge.
Criterion-by-criterion evidence
Every score below is a recorded, dated observation. Where we could not verify a claim, the criterion is marked Unverified and excluded from the score (but it still counts against coverage).
| Criterion | Wt | Finding | Evidence |
|---|---|---|---|
| Publishes CoAsThe vendor publishes at least one certificate of analysis (CoA) on its own website. | 3 | ✔ Yes | Public page: 13 SARM CoAs and 25 peptide CoAs as images, no login. Source · 2026-07-09 |
| Batch-level CoAsCoAs are tied to a specific batch/lot number, not a single generic certificate per product. | 3 | ✔ Yes | "Most recent batch CoA, issued by MZ Biolabs"; lot numbers appear in the CoA images. Source · 2026-07-09 |
| Third-party lab namedThe name of the laboratory that ran the analysis appears on the CoA. | 2 | ✔ Yes | CoAs issued by a named lab: MZ Biolabs. Source · 2026-07-09 |
| Independent / accredited labThe lab is independent of the vendor and/or accredited (ISO 17025), or is a recognised independent peptide lab (e.g. Janoshik, MZ Biolabs). | 2 | ✔ Yes | MZ Biolabs is a recognised independent peptide/SARM lab, DEA-licensed, running Bruker QTOF MS (ISO 17025 not declared). Source · 2026-07-09 |
| CoA verifiable at sourceThe CoA can be authenticated on the laboratory's own website (e.g. a verification code) — actually tested, not just claimed. | 2 | ✘ No | MZ Biolabs offers no online verify/QR; authentication is by phone only. Source · 2026-07-09 |
| Identity + purity methodsWhich analytical methods are identifiable on the published CoAs. | 2 | ? Unverified HPLC + MS | "HPLC with UV + mass spectrometry"; MOTS-c cited at 99.66% HPLC purity. Source · 2026-07-09 |
| Freshness of the latest CoADate of the most recent CoA visible on the site. | 2 | ? Unverified 3-12 months | CoAs from 2023 to 2026, with 2026 certs present; a <3-month date could not be confirmed → lt12m (conservative). Source · 2026-07-09 |
| CoAs accessible before purchase, no accountCoAs can be viewed without a customer account or a prior purchase. | 2 | ✔ Yes | "Published on our website — no login required." Source · 2026-07-09 |
| Sterility / endotoxin data publishedSterility or endotoxin (LAL) results are published in addition to purity. | 1 | ✘ No | The lab explicitly excludes sterility/endotoxins, heavy metals and pH. Source · 2026-07-09 |
| Public complaints / recall handlingA public recall/complaint policy, or documented handling of a disputed batch. | 1 | ? Unverified | Not verified — no evidence on record. |
