Pros & Cons

Pros

  • Among the most aggressive per-mg pricing we track across the GLP-1 class — Tirzepatide (TRZ-2) at roughly $2–3/mg single-vial and Retatrutide (GLP-3) at roughly $3.30/mg undercut every other vendor's single-vial pricing at comparable sizes
  • Deep per-vial tiering on Tirzepatide (20 / 30 / 40 / 60 mg) — larger sizes for extended protocol research without needing a 10-vial kit commitment
  • Broad mix of modern compounds — 5-Amino-MQ, Cagrilintide, MOTS-C, Thymosin Alpha-1, Prostamax / Testagen / Cartalax bioregulators, plus GLP-class
  • 10-vial kits on core peptides (NAD, Tirzepatide, GHK-Cu) for bulk-purchase research workflows
  • Research-capsule line (BPC, KPV, SLU-PP-332, Tesofensine, 5-Amino-MQ) for oral-delivery research protocols — uncommon across research-peptide vendors

Cons

  • Stock rotation appears aggressive — several hero single-vials (BPC-157 10/20mg, TB-500 10/20mg, MT-2, KissPeptin) were listed OOS at last scrape
  • Third-party Janoshik / Finnrick COAs not surfaced on the public site
  • Newer entrant (late-2025 first scrape in our data) — community history is thinner than Ascension, Pantheon, or Limitless
  • Customer-side coupon is a personal name in the vendor's dashboard — we route discount through the affiliate link instead of publishing the code
