comment on LC-MS: the version I wish someone had shown me in week 1 in c/hplc · 1 points · 10 months ago

chromatogram or it did not happen

comment on [Lab] 23th independent test on QSC, and the trend is the interesting part in c/glp1uk · 95 points · 11 months ago

NHS or private?

comment on am I the only one who found Medutest harder than the injections in c/vendorvetting · -29 points · 11 months ago

Respectfully this is a sample of one presented as a finding.

comment on does purity actually matter or is it forum lore at this point in c/hplc · 47 points · 11 months ago

Detection wavelength? HPLC and that changes at different wavelengths.

comment on why does nobody talk about VendorInvestigate in c/vendorvetting · 29 points · 11 months ago

the reship rate on BCH is actually pretty consistent

Disagree on that part. 98.1% and 98.3% on the same vial is normal.

comment on three years of purity threads, summarised so you do not have to read them in c/hplc · 10 points · 1 year ago

Did they post the raw trace or just the summary?

comment on what changed for me between week 25 and week 68 in c/vendorvetting · 1.2k points · 1 year ago

GL Biochem took 10 days to answer an email and the material was flawless. Both of those things are true.

comment on reading lean mass threads from 2024 and half of it aged badly in c/glp1muscle · 24 points · 1 year ago

nope. mine was the opposite.

comment on small win: sarcopenia stopped being a problem at week 31 in c/glp1muscle · 9 points · 1 year ago

lean mass retention is the 68 week conversation

comment on small win: sarcopenia stopped being a problem at week 31 in c/glp1muscle · 27 points · 1 year ago

The thing nobody prepared me for was the quiet. Not the appetite, the quiet. The constant negotiation in my head about food just stopped.

comment on small win: sarcopenia stopped being a problem at week 31 in c/glp1muscle · 31 points · 1 year ago

The injection-site soreness was genuinely awful for three weeks and then simply stopped. I know that is not useful information, but it is what happened.

comment on anyone else notice resistance training kicking in around week 75 in c/glp1muscle · 23 points · 1 year ago

This is correct. DEXA is the standard.

comment on formulary — 13 things I got wrong before I got it right in c/glp1canada · 10 points · 1 year ago

Respectfully this is a sample of one presented as a finding.

comment on MHRA: the version I wish someone had shown me in week 1 in c/glp1uk · 37 points · 1 year ago

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

comment on [Question] Sweden — has anyone got a straight answer on MHRA in c/glp1uk · 0 points · 1 year ago

private prescription routes vary by region

comment on [Lab] SGN tirz — VendorInvestigate came back 93.7% against a claimed 94.2% in c/vendorvetting · 0 points · 1 year ago

Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

comment on switched from 1.7mg to 1.0mg and the reflux got better, not worse in c/hplc · 25 points · 1 year ago

a round-robin on baseline integration would be genuinely useful

permalink

comment on purity — 8 things I got wrong before I got it right in c/hplc · 9 points · 1 year ago

state the method: column, gradient, detection wavelength, injection volume

permalink

comment on purity — 8 things I got wrong before I got it right in c/hplc · 22 points · 1 year ago

axis labels included, always

comment on purity — 8 things I got wrong before I got it right in c/hplc · 42 points · 1 year ago

Removed a chain here.

Adding to this: chromatogram is doing more work than the comment implies.
