Pros & Cons

Pros

  • Aggressive multi-tier GLP-class sizing — Tirzepatide (GLP-2TZ) in 4 sizes (10/15/30/60mg), Retatrutide (GLP-3RT) in 3 sizes (10/15/30mg), Semaglutide (GLP-1SG) in 4 sizes (10/15/20/30mg). Researchers running scaled protocols can buy a single larger vial instead of multiples
  • 60mg single-vial Tirzepatide ($250) and 30mg single-vial Retatrutide ($190) — uncommonly large sizes at this price tier
  • Three-tier SS-31 sizing (10mg / 50mg) and two-tier 5-Amino-1MQ (5mg / 10mg) — multi-tier mitochondrial / metabolic options for scaled protocols
  • Strongest research-only legal disclaimer posture across most pages — every product page footers a multi-paragraph 'NOT FOR HUMAN CONSUMPTION' notice, which protects the vendor and lines up with the FDA's expected research-grade marketing
  • Customer coupon STACKED for 15% off at checkout — among the larger first-order discounts on file
  • Niche peptide depth — VIP, Survodutide, LL-37, Adipotide-equivalent compounds, KPV, Cagrilintide alongside the mainstream catalog

Cons

  • Multi-format catalog spans peptides, lipotropics, skincare, apparel, and one SARM — researchers focused only on injectable peptides may need to filter manually
  • Third-party COA (Janoshik / Finnrick / equivalent) provider not surfaced on the public site — independent purity verification not currently published
