Verified purchaseGood selection, mediocre packaging
Pros: Fair pricing (with discount code), good selection of products, COA's included testing for endotoxins and heavy metals (not all suppliers go this far with their COAs), easy to order and pay online, shipping speed was ok. Only con: Shipping packaging in my opinion was mediocre -loose vials in a shipping style envelope (could have broken easily with carrier mishandling) and no real temperature control measures.
