NextGen Peptides Gonadorelin: content discrepancy in PI-LAB-2025-055

NextGen Peptides's Gonadorelin came back with a discrepancy, specimen PI-LAB-2025-055 if you want to look at it yourself.

Purity was actually fine at 97.3%. The problem is the amount, 2.05mg measured against 2mg on the label. Which is the kind of thing a purity-only COA sails straight past.

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

Still not convinced but I take the point.

Worth adding that this only holds for lyophilised product.

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.
