purity. That is the whole post, but I will justify it. Everything else people worry about in c/sideeffects is downstream of it. Titration speed, muscle cramps, the…
I have had 13 orders now and I keep a table, so here is the honest summary rather than a vibe. Material has been consistent. Communication has not. Shipping has varied…
Been lurking in c/survodutide for about 14 months and finally have something worth posting. Short version: week 15, 1.7mg, and COA is the bit I still cannot get a…
Genuinely asking, not being difficult. Everyone in c/scamalerts repeats that area percent is important. I believe it, but I have never seen anyone show why, and when I…
Send the vial, get the number. Third-party purity and identity testing, results published to you regardless of what they say.
Test a vialSponsoredEst. 1998. ISO 9001 and cGMP, 1,500+ staff, 200+ patents. There is a fair chance the vial you are about to send for testing started here. Batch-specific COA as standard.

Long-ish post, sorry. tl;dr at the bottom. I have been tracking area percent against ApoB for 31 weeks because I could not find anyone who had. The correlation is…
Trying to settle this properly because the thread from last year went in circles. The claim: related substances matters. The counter-claim: it is measurement error.…
Following on from the area% thread, because the same confusion turns up in a second form. People read a 10mg vial at 99% purity and conclude they have 9.9mg of peptide.…

Quick one. Canada here. related substances works very differently where I live than in the threads that dominate the front page, and I keep seeing people confidently…
Week 71 update. 37kg down from the start, early fullness basically gone since about week 16. Things that worked: consistency, protein at breakfast, walking more than I…
Confession thread, sort of. I went from 0.5mg to 12.5mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 17 weeks…

Week 11 update. 22kg down from the start, muscle cramps basically gone since about week 51. Things that worked: consistency, protein at breakfast, walking more than I…
Vendor-level purity averages over time, built from independent results rather than vendor claims. Transparent methodology, open dataset.

FGP cagrilintide. The document has a compound name, a purity figure, a logo, and a signature image. No batch number. No date of analysis. No method beyond the word…

Right, the COA question again, but with numbers this time. I have 8 data points over 20 weeks. The pattern is consistent enough that I do not think it is chance, and…
Short answer, for anyone who finds this from a search: no. Longer version. A COA from an actual laboratory is exported from instrument software or from a LIMS. The PDF…

How to read a certificate of analysis and what it does and does not tell you. Area% versus mass%, identity versus quantity, water content, related substances, acetate counterions, and the difference between a vendor-supplied COA and an independent test on the vial you actually received.
