Prove It Performance — solid COAs, fast shipping

Have ordered from PIP three times in the last 4 months. COAs are third-party verified, lot numbers match the vials. The mass spec data has been within tolerance on everything I've checked.

Shipping is reliably fast. Packaging is appropriate (insulated for the temp-sensitive stuff). No issues with any of the orders.

Prices are middle of the market — not the cheapest but not overpriced. Value rating reflects that competition exists.
