Bought a second-hand HPLC and a lifetime of regret. I post chromatograms, not conclusions.

comment on week 31 check-in — 6kg down, constipation manageable, one thing confusing me in c/bpc157 · 7 points · 5 months ago
handlers in the community are rare and cautious
comment on the Netherlands: purity, and what it actually costs here in c/hplc · 19 points · 6 months ago
Strongly agree. Largest single impurity tells a different story than total purity.

lane reports need origin, destination, carrier, and actual transit days

CagriSema is a fixed combo in trials, not user-mixed

Retitled to remove editorialising. Put the evidence in the body.

the detector wavelength matters more than people think

The related substances profile is way more interesting than the main peak %. A 98% with 12 peaks is different from a 98% that is one 38% impurity.

tendon and cagrilintide literature in rodents is interesting

regulatory status varies by country, check yours

Did anything else change in the same window?

redact member ids and group numbers from every screenshot
comment on does LC-MS actually matter or is it forum lore at this point in c/hplc · 7 points · 7 months ago
Flair changed to match the content. Read the sidebar before posting next time and we are square.

comment on rodent data: what the trials say vs what this community says in c/bpc157 · 53 points · 8 months ago
The confident tone is doing a lot of work that the evidence is not.
comment on [Lab] 24th independent test on QSC, and the trend is the interesting part in c/hplc · 175 points · 8 months ago
Retitled to remove editorialising. Put the evidence in the body.
comment on [Discussion] the CagriSema advice in here is 14 years out of date in c/cagrilintide · 7 points · 8 months ago
CagriSema ratios in trials are fixed, do not extrapolate self-mixing
comment on am I the only one who found TB-500 harder than the injections in c/researchpeptides · 9 points · 8 months ago
Yeah, identity is the first question.
comment on someone explain appeal to me like I have not read a paper in years in c/insurancefights · 43 points · 9 months ago
That is net peptide content, not purity. Different number, different meaning.

The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.
comment on [Discussion] pentadecapeptide is doing more work than we give it credit for in c/bpc157 · 17 points · 9 months ago
Small correction: the trial was 3 weeks, not 17. Does not change your point but people will quote it.
