About Sports Technology Labs

Sports Technology Labs is a Shelton, Connecticut-based research compound vendor founded in 2019. Originally focused on SARMs (Selective Androgen Receptor Modulators), the company has expanded into the peptide market with a curated selection of approximately 12 popular research peptides. They are one of the few vendors to publicly name their third-party testing laboratory, MZ Biolabs, and make all certificates of analysis freely accessible on their website. The company offers a 10% discount for cryptocurrency payments and free shipping on orders over $149. Their transparency around testing sets them apart, though their peptide catalog remains smaller than dedicated peptide-only vendors.

Source's COA tier
third-party

All COAs are produced by named third-party laboratory MZ Biolabs and are publicly accessible on each product page. This level of testing transparency is uncommon among US peptide vendors. observed

A COA describes one batch's purity. It is a document about a vial, not evidence about an effect, and it never grades a claim on this site — the grading rubric names what qualifies.

Peptides listed 12

Linked names have a record here; the others we hold nothing on yet. A vendor listing a compound says nothing about the evidence for it.
