Recent PIP tirzepatide lot 250318. Standard third-party COA present. HPLC clean. MS confirmation present.
Minor flag: the net peptide content was reported but in slightly different format than previous lots. Same vendor's documentation has gotten slightly inconsistent on this specific data point over time. Not a quality issue, a docs consistency issue.
