Every GLP Research Hub submission tagged to COA, ranked by score. Discussed in 1 community.
Trying to settle this properly because the thread from last year went in circles. The claim: fake COA matters. The counter-claim: it is measurement error. Both sides…
Two weeks ago I posted that a QYB certificate had a producer string inconsistent with laboratory software and implied it was generated. It was a re-export. The original…
Posting this because I searched for it and got nothing useful. Setup: 0.25mg, week 28, injection-site soreness present but not ruining anything. I changed exactly one…
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…
Reference standards, analytical reagents and system-suitability material. If you are running your own method, start with a known.

Confession thread, sort of. I went from 7.5mg to 2.4mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 6 weeks…
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…
Quick one. Canada here. certificate of analysis works very differently where I live than in the threads that dominate the front page, and I keep seeing people…
Right, the certificate of analysis question again, but with numbers this time. I have 9 data points over 14 weeks. The pattern is consistent enough that I do not think…
exit scam. That is the whole post, but I will justify it. Everything else people worry about in c/cryptopay is downstream of it. Titration speed, reflux, the endless…
Confession thread, sort of. I went from 1.0mg to 15mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 14 weeks…

I have had 10 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…

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.

Something I noticed reading old threads that I have not seen said out loud. The advice on telehealth in this community changed substantially around the start of last…
Week 50 update. 31kg down from the start, muscle cramps basically gone since about week 90. Things that worked: consistency, protein at breakfast, walking more than I…
Posting this because I searched for it and got nothing useful. Setup: 12.5mg, week 79, sulphur burps present but not ruining anything. I changed exactly one variable —…
Ran these on the same day, same method, same column, injections back to back. One is GL Biochem raw material, one is a reseller vial of nominally the same compound and…
Long-ish post, sorry. tl;dr at the bottom. I have been tracking certificate of analysis against ApoB for 39 weeks because I could not find anyone who had. The…
Been lurking in c/survodutide for about 10 months and finally have something worth posting. Short version: week 87, 1.0mg, and batch is the bit I still cannot get a…
Long-ish post, sorry. tl;dr at the bottom. I have been tracking batch against triglycerides for 17 weeks because I could not find anyone who had. The correlation is…
Week 21 update. 7kg down from the start, reflux basically gone since about week 61. Things that worked: consistency, protein at breakfast, walking more than I want to.…
