Real, verified orders dispatched from our NY facility in the past hour. Every order ships with a batch-matched COA.
Sent the BPC-157 vial to a third-party lab for independent HPLC verification. Result came back at 99.2% — within 0.3% of the supplied COA. This is the level of consistency we look for.
Ordered Tirzepatide at 11:40am ET on a Tuesday. Got tracking by 2:15pm, arrived in Austin 36 hours later in insulated packaging with ice packs still cold. Exactly as advertised.
COA included retention time, mass spec confirmation, residual solvent screen — not just a percent number on a screenshot. This is what reproducible research requires.
