NextGen Peptides's Tirzepatide came back with a discrepancy, specimen PI-LAB-2026-0005 if you want to look at it yourself.

Has anyone else bought from this lot? Trying to work out if it's just this batch or something broader.

Batch-to-batch variation is the thing people underestimate. A passing result certifies one lot, not a product line, and vendors know most buyers do not make that distinction.
