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 know is whether the people saying it does not matter have measured it, or whether it is just repeated confidently. Happy to be told I am overthinking this — I probably am — but I would rather overthink it now than at week 63.
best — the order this archive was captured in
no "is this good?" without saying what the compound and claimed purity are
You have restated the marketing copy. What is the actual substance here.
No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.
Tested the GLB raw material and a reseller vial side-by-side. Same purity claim, different impurity profiles. Handling matters.
the counterion is part of the mass you paid for

Cosigning. The batch number is load-bearing information.
the batch number or it did not happen
purity and net content are two different numbers, same vial
Half-life is about 168 hours, so steady state lands around week 13–5. Practical consequence: what you feel in week 1 is not what that dose does.
What is the method line say? Not the technique, the actual method.
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.

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

Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.
