Pros & Cons

Pros

  • Aggressive single-vial pricing — many peptide SKUs land in the $20-$35 range, with Tirzepatide (GLP-1/GIP RA) at $69.95 for 5mg ($14/mg) and $109.95 for 10mg ($11/mg), Retatrutide (GLP-3) at $69.95 for 5mg ($14/mg) and $159.99 for 15mg ($10.66/mg)
  • Established storefront with copyright dating to 2017 — longer operating history than most newer vendors
  • Two GLP-class size tiers (5mg + 10mg Tirzepatide; 5mg + 15mg Retatrutide; 5mg + 15mg Semaglutide) — useful for researchers running scaled protocols without committing to the larger vial
  • US-based fulfillment from West Palm Beach, FL with Monday-Friday shipping cutoff at 3PM EST

Cons

  • Multi-category catalog includes SARMs, thyroid hormones, anti-aromatase agents, prolactin agents, and PDE5 inhibitors — a broader scope than pure-peptide vendors
  • Third-party COA (Janoshik / Finnrick / equivalent) provider not surfaced on the public site — independent purity verification not currently published
