Is Sports Technology Labs legit?
Sports Technology Labs scores 6.88 out of 10 (Fair, #38 of 100) as of November 1, 2026 and passes our testing gate: 15 of the 16 products we score carry a certificate, 15 confirmed with the issuing lab (a lab we grade A). Its strongest area is shipping and refunds (10.0/10) and its weakest is transparency (3.5/10); its operating history on record covers over seven years.
On lab evidence, the heaviest-weighted factor, Sports Technology Labs has independently verified third-party COAs, with COA work on record from MZ Biolabs. Its lowest price per milligram in our data is on GHK-Cu (see the table below).
How this score was calculated
Every point below follows the published tables in our methodology, with the policy wording we scored and a link to where we read it. Evidence last checked October 22, 2026. Lab credibility is worked product by product from the certificates on file.
Lab credibility6.6/10
Each carried product (lab supplies excluded) is scored from the certificate on file for it, on the published lab rubric: 3 for a published certificate, then points for the laboratory, the verification key, the tests on the certificate and its purity, held to 0 to 10. A certificate that is self-issued, names no laboratory, or comes from a laboratory whose independence is not established scores a flat 2.0; a product with no certificate, a certificate the laboratory’s own record fails, or a posted copy that differs materially from the laboratory’s copy scores 0. Calculated on , the day this page was built; the date each certificate was tested is shown on its row.

Market medians updated after Bluum Peptides was added pricing 4.8 to 4.6.
- Audit · 6.99to6.88
Lab score recalculated on 30 October 2026 under rule A6 (certificate age): the PEG-MGF certificate, tested on 29 October 2025, became older than 12 months on 30 October 2026 and joins the four certificates tested on 17 October 2025 that already were; each certificate older than 12 months counts for a quarter less.

Pricing recomputed on 24 October 2026 after Bionova Peptides' first-review prices were recorded; other vendors move only through the market medians: pricing 5.0 to 4.7.
- Audit · 7.05to7.02
Pricing recomputed on 23 October 2026 from current listings with the published rule (section E), after listings added or updated since 22 October, including a newly reviewed vendor's, moved the market median for the same products: pricing 5.2 to 5.0.
- Audit · 6.89to7.05
Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 6.5 to 6.8.
- Audit · 6.88to6.89
Operating history re-checked on 22 October 2026 under the published rule (earliest dated evidence of the business, including a never-parked store domain and the named operating company, looked up for every vendor): operating history 7.0 to 7.1.
- Audit · 6.40to6.88
Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 7.0 to 10.0, pricing 5.5 to 5.2, transparency 5.0 to 3.5.
- Audit · 5.74to6.40
Certificate verification keys confirmed on 22 October 2026 at MZ Biolabs' own certificate page, which only opens in a browser, and the lab score recalculated under the uniform rubric. Lab 5.3 to 6.5.
- Audit · 5.85to5.74
Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for certificates more than 12 months old, one lot number printed on certificates for different compounds and site statements about testing that the certificates do not bear out. Lab 5.5 to 5.3.
- Audit · 6.01to5.85
Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 15 of the 16 products we list that the vendor offers for sale. Lab 5.8 to 5.5.
- Audit · 6.83to6.01
Re-audited 2026-10-18, replacing a May 2026 seed score that was never properly audited. Lab rises from 5.3 to 5.8: every tracked peptide now has an MZ Biolabs report, most refreshed in 2026, and newer reports link to the laboratory's own site, where the BPC-157 report was confirmed; five reports date from October 2025. Shipping falls from 9.0 to 7.0 because the terms disclaim responsibility for lost shipments and offer no reship policy, while the 60-day money-back guarantee holds it up. Pricing falls from 8.5 to 5.5 because standard prices sit well above the market median. Tenure moves from 8.5 to 7.0 for a domain registered in August 2019. Transparency falls from 7.9 to 5.0: an address and phone, but no legal entity, governing law or named people. Semax is now recorded as carried.
Editor’s notes
Sports Technology Labs shows a certificate from MZ Biolabs, an independent laboratory in Tucson, for every peptide we track. Most are dated May to September 2026; five date from October 2025, a year before this review. The reports cover identity and purity only, with no endotoxin or sterility testing, and purity runs from 98.6% to 99.9% apart from Selank at 96.8%. Newer reports carry a QR code that links to the laboratory's own certificate viewer; by 22 October 2026 we had confirmed all fifteen certificates on MZ Biolabs' own certificate page, and the BPC-157 record names Sports Technology Labs as the client. The BPC-157 report describes a 10mg sample while the product is sold in 5mg vials. The site describes its laboratories as accredited, which MZ Biolabs does not claim. The vendor's about page states that most orders ship the same day, with free domestic shipping above a threshold and an express option. The vendor offers a 60-day money-back guarantee and free exchanges of unused items within 60 days, and accepts cards along with Zelle, CashApp and crypto. Standard prices run well above the market median for most products. The domain dates from August 2019. As of October 2026, 15 of the 16 products we list show an MZ Biolabs certificate covering identity and purity only, five of them from lots analysed in October 2025; the CJC-1295 and Ipamorelin blend shows only certificates for the two separate peptides.
