comment on [Discussion] can we stop arguing about area percent until somebody posts a number in c/coa · 176 points · 2 years ago
comment on [Discussion] the related substances advice in here is 15 years out of date in c/coa · 622 points · 2 years ago
Water content was 3.8%, acetate was 6.2%, purity was 99%, but net peptide was only 90% of the label weight. Perfectly honest, just chemistry.
comment on [Discussion] we are measuring Zepbound at the wrong time and calling it noise in c/tirzepatide · 18 points · 2 years ago
Sceptical. If this were true we would see it reflected in the data and we do not.
comment on [Results] 57 weeks, 20kg, and tirzepatide was the hard part in c/tirzepatide · 188 points · 2 years ago
Hard agree. The food noise disappears differently on the two compounds.
comment on [Meta] the batch rule is doing its job and people should stop complaining in c/coa · 54 points · 2 years ago
the method line is doing real work, not just window dressing
comment on is it normal to get injection-site soreness at week 29 in c/vendorvetting · 99 points · 2 years ago
Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.

no "is this good?" without saying what the compound and claimed purity are

Respectfully this is a sample of one presented as a finding.
comment on [Vendor] QST order #11 — Denmark, 7 days, no drama, receipts inside in c/vendorvetting · 94 points · 2 years ago
Correct. The batch number is load-bearing information, not optional.
comment on [Vendor] WXT order #5 — the Netherlands, 35 days, no drama, receipts inside in c/coa · 2.5k points · 2 years ago
comment on switched from 0.25mg to 1.7mg and the nausea got better, not worse in c/coa · 212 points · 2 years ago
Tested the GLB raw material and a reseller vial side-by-side. Same purity claim, different impurity profiles. Handling matters.
