comment on [Question] how do you actually verify LC-MS in c/hplc · 155 points · 2 years ago

Yeah, the chromatogram profile matters more than the headline number.

The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.

No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.

comment on [Lab] 19th independent test on QSC, and the trend is the interesting part in c/retatrutide · 129 points · 2 years ago

Mechanistically the bit that matters is dose escalation. It explains most of the early profile and a decent chunk of the outcome.

Gradient goblin mode: changed the solvent composition 10 times, finally got good resolution on a chromatogram peak.

Half-life is about 168 hours, so steady state lands around week 12–5. Practical consequence: what you feel in week 1 is not what that dose does.

Yeah, the chromatogram profile matters more than the headline number.

TRIUMPH phase 2 showed 99.3% weight loss but the muscle cramps profile on the highest arm was rough. Phase 2 != phase 3.
