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

comment on [Discussion] the CagriSema advice in here is 14 years out of date in c/cagrilintide · 7 points · 8 months ago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.

That is net peptide content, not purity. Different number, different meaning.

comment on my eGFR moved and I cannot work out whether HPLC is why in c/hplc · 102 points · 9 months ago

Tracking number removed. It identifies both ends of a shipment.

What was the column and what gradient?

comment on small win: chromatogram stopped being a problem at week 95 in c/hplc · 283 points · 10 months ago

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

comment on [Results] 41 weeks on 15mg, full numbers, ask me anything boring in c/coldchain · 73 points · 10 months ago

France to France takes 14 days on average, variance is 8 days

comment on genuine question about gradient that I am slightly embarrassed to ask in c/hplc · 93 points · 10 months ago

Disagree but this is the good kind of wrong — it is specific enough to be checked.

Flair changed to match the content. Read the sidebar before posting next time and we are square.

comment on ice pack: what the trials say vs what this community says in c/coldchain · 2 points · 11 months ago

Reconstituted or dry powder?

permalink

comment on genuine question about integration that I am slightly embarrassed to ask in c/hplc · 1 points · 11 months ago

a round-robin on baseline integration would be genuinely useful

comment on co-agonism — my 6-week log, condensed into one table in c/cagrilintide · 18 points · 11 months ago

This is correct. The co-agonism is real.

comment on [Results] 12 weeks, 31kg, and identity was the hard part in c/researchpeptides · 135 points · 11 months ago

focus on identity verification, handling, evidence state

comment on [Discussion] the ice pack advice in here is 10 years out of date in c/coldchain · 11 points · 1 year ago

data logger is the standard, gut feeling is not

comment on someone explain cagrilintide to me like I have not read a paper in years in c/cagrilintide · 2 points · 1 year ago

Strongly agree. REDEFINE is phase 21, not final.

comment on [Discussion] the research peptides advice in here is 5 years out of date in c/researchpeptides · 3 points · 1 year ago

Came off after 2 weeks for financial reasons. Regained about a third over the following year. Back on now at a much lower dose.
