comment on what does titration actually mean in c/newbiequestions · 1 points · 3 days ago
Disagree. What you are describing is consistent with basics, not with what you concluded.
Long-ish post, sorry. tl;dr at the bottom. I have been tracking shipping against triglycerides for 7 weeks because I could not find anyone who had. The correlation is…
comment on peak at 4.2 min, nobody can tell me what it is, ideas in c/hplc · 1 points · 4 days ago
Did they post the raw trace or just the summary?
Yes, exactly this, and it is the bit that took me 93 weeks to accept.
comment on [PSA] no tracking numbers. they identify both ends. removed on sight. in c/intlshipping · 35 points · 4 days ago
Slight fix: the number was 96.8, not 97.2.
Yes, exactly this, and it is the bit that took me 82 weeks to accept.
comment on [Lab] three BPC vials, three vendors, purity all over the place in c/bpc157 · 0 points · 4 days ago
Half-life is about 168 hours, so steady state lands around week 20–5. Practical consequence: what you feel in week 1 is not what that dose does.
comment on bought a second-hand HPLC. worst best decision of my life. AMA in c/hplc · 4 points · 9 days ago
the gradient is doing the separation work, not the column alone
comment on [Lab] identity confirmed but net peptide content was 71% in c/bpc157 · 9 points · 16 days ago
Three years on this site and the questions have not changed at all. Which is depressing or reassuring depending on the day.
comment on retention time shifted 0.4 min and nobody wants to talk about it in c/hplc · 22 points · 18 days ago
A shoulder on the main peak that 2 analysts integrated 40 different ways. Same trace, 98.1 spread.
comment on [Lab] my running table: 34 tests, 11 vendors, three years in c/labresults · 1 points · 19 days ago
Not to be pedantic but batch and test results are being used interchangeably and they are not interchangeable in real life.
comment on [Below Spec] 88% is not "basically fine" and i am tired of that reply in c/labresults · 27 points · 23 days ago
Tested 14 batches from QST over 90 weeks. Spread was 99.2% to 99.1, mostly 99.2. Consistent vendor.
comment on integration vs method development — genuinely asking which matters more in c/hplc · 251 points · 24 days ago
Gradient goblin mode: changed the solvent composition 16 times, finally got good resolution on a gradient peak.
comment on why do people talk about units and mg like they are different things in c/newbiequestions · 20 points · 29 days ago
This is a good question, genuinely.
comment on someone explain chromatogram to me like I have not read a paper in years in c/hplc · 14 points · 1 months ago
integration decision on a shoulder changes your number by half a point on its own
comment on is the wiki up to date, and where do i start in it in c/newbiequestions · 17 points · 1 months ago
What does the wiki say?

no supplement selling, no coaching solicitation
comment on [Lab] SSA BPC — Medutest came back 97.4% against a claimed 96.2% in c/bpc157 · 17 points · 1 months ago
Came off after 16 weeks for financial reasons. Regained about a third over the following year. Back on now at a much lower dose.
comment on does gradient actually matter or is it forum lore at this point in c/hplc · 38 points · 1 months ago
I am going to push back on this slightly.
comment on the resistance training question that gets asked weekly, answered properly in c/glp1muscle · 10 points · 1 months ago
resistance training is sarcopenia not optional
comment on my eGFR moved and I cannot work out whether LC-MS is why in c/hplc · 64 points · 1 months ago
The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.
