comment on testing — 12 things I got wrong before I got it right in c/vendorvetting · 28 points · 8 months ago
Titration speed is a side-effect dial far more than an efficacy dial.
comment on what would you tell week-1 you about Medutest in c/vendorvetting · 64 points · 9 months ago
vendor staff must self-identify, full stop
comment on genuine question about testing that I am slightly embarrassed to ask in c/vendorvetting · 208 points · 9 months ago
First order from HJ was great, second one had a different batch and tested lower. The vendor retested and credited me. Logged it here.
comment on LC-MS: the version I wish someone had shown me in week 1 in c/hplc · 34 points · 10 months ago
area% and mass% are not the same and this whole post conflates them
comment on 21 months in and HPLC is still the thing I get wrong in c/hplc · 49 points · 11 months ago
Injection volume and flow rate? Those affect resolution.
comment on does purity actually matter or is it forum lore at this point in c/hplc · 45 points · 11 months ago
Ran the same vial on two columns, different purity, both right, different separation. Method matters more than equipment.

A shoulder on the main peak that 14 analysts integrated 35 different ways. Same trace, 97.6 spread.

comment on [Discussion] we are measuring discontinuation at the wrong time and calling it noise in c/tapering · 20 points · 12 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.
comment on [Results] 32 weeks, 45kg, and regain was the hard part in c/tapering · 15 points · 1 year ago
What was the batch number and which service?

interval stretching versus dose reduction
comment on tried Janoshik for 9 weeks. here is what happened. in c/vendorvetting · 7 points · 1 year ago
order date, product, and what was tested. that is the template.
comment on tried interval stretching for 5 weeks. here is what happened. in c/tapering · 2 points · 1 year ago
STEP 1 and SURMOUNT-4 discontinuation arms show regain
comment on anyone else notice cycle kicking in around week 15 in c/glp1women · 68 points · 1 year ago
Australia here. Waited 10 months on a list, gave up, went private, and the total cost was roughly what I expected.

Half-life is about 168 hours, so steady state lands around week 8–5. Practical consequence: what you feel in week 1 is not what that dose does.
comment on tapering vs regain — genuinely asking which matters more in c/tapering · 25 points · 1 year ago
Small correction: the trial was 18 weeks, not 31. Does not change your point but people will quote it.
comment on [Question] how do you actually verify Medutest in c/vendorvetting · 4 points · 1 year ago
Did you test the vial you received or are we going off the vendor COA?
comment on my ApoB moved and I cannot work out whether method development is why in c/hplc · 18 points · 1 year ago
Disagree. What you are describing is consistent with gradient, not with what you concluded.

comment on [PSA] chromatogram is not what most of this community thinks it is in c/hplc · 5 points · 1 year ago
state the method: column, gradient, detection wavelength, injection volume Disagree on that part.
Yes, exactly this, and it is the bit that took me 94 weeks to accept.
