NextGen Peptides's Survodutide came back with a discrepancy, specimen PI-LAB-2024-062 if you want to look at it yourself.
Purity was actually fine at 98.4%. The problem is the amount, 2.74mg measured against 3mg 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.
No replies yet. Be the first to add one.
The methodology page covers the weighting question directly. Purity gets the largest share because it is the most reliably measurable thing they assess.
Short answer: check that the lot number on the certificate matches the lot printed on your vial. If it does not, the document is about different material.
Correct, and the same applies to the quantity assay.
The people who get burned are almost never the ones who asked questions first.
Was just about to ask this.
