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

comment on three years of packaging threads, summarised so you do not have to read them in c/coldchain · 54 points · 4 months ago

data logger is the standard, gut feeling is not

comment on my triglycerides moved and I cannot work out whether tendon is why in c/bpc157 · 37 points · 4 months ago

My version of this: I was so worried about the injection that I put it off for eleven days. The injection is the easiest part.

Detection wavelength? purity and that changes at different wavelengths.

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

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.

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.

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.
