COA: what the trials say vs what this community says
Been lurking in c/tirzepatide for about 22 months and finally have something worth posting. Short version: week 69, 1.7mg, and water content is the bit I still cannot get a straight answer on. I have read the wiki, I have read the last 15 threads, and the answers split roughly down the middle. What I actually want to…
Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.
Asked SGN for the batch-specific COA and they sent it within six hours, full document, batch number, date, everything. That is the baseline.
What is the method line say? Not the technique, the actual method.
area% is not mass%, and here is exactly why it matters

Yes, exactly this, and it is the bit that took me 10 weeks to accept.
Water content on the document? That affects your concentration math.
post the whole document, not the headline number
You have restated the marketing copy. What is the actual substance here.
Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.
chromatogram or it did not happen

Cosigning. The batch number is load-bearing information.
