Cellpept

Visit site

23 of 44 tracked listings have a confirmed, named third-party lab COA.

Shipping: EU-wide shipping from the Netherlands.
Lab verification: Just over half of tracked listings link directly to a Janoshik Analytical report (purity, and often endotoxins/heavy metals too) or appear in Cellpept's own COA library; the rest — mostly newer or more niche compounds (Semaglutide, Cagrilintide, Thymosin Alpha-1, and several others) — show no COA or purity claim at all on the product page.
