Pros & Cons
Pros
- Multi-format delivery, same peptides offered as injectable vials, nasal sprays, and oral tablets, unusual breadth for a research vendor
- Public /coa/ library publishing per-batch certificates of analysis from independent third-party analytical labs
- Unusually deep Khavinson bioregulator line (Vesugen, Testagen, Ovagen, Pancragen, Cortagen, Cardiogen, Bronchogen, Chonluten, Livagen) alongside the modern GLP class
- Aggressive single-vial pricing on staples, GHK-Cu 50mg at $18 and Semax 10mg at $38 land near the low end of our tracked $/mg
- Credit-card and cryptocurrency checkout
Cons
- Newer vendor, operating footprint and long-term community history are thinner than established shops
- Third-party COAs are independent-lab but the lab is not named in the rendered COA page (results self-hosted as batch PDFs)
- Several compounds are sold only in non-vial formats (nasal spray or oral tablet), which sit outside the vial $/mg comparison
