comment on what would you tell week-1 you about weekly update in c/dosinglogs · 248 points · 1 year ago
The evidence standard in c/vendorvetting gets called too strict about once a month, and every time, the thread ends with the complainant agreeing.
comment on stalled for 8 weeks at 5mg and I refuse to panic this time in c/hplc · 45 points · 1 year ago
Yeah, the chromatogram profile matters more than the headline number.
comment on lyophilised vs stability — genuinely asking which matters more in c/coldchain · 74 points · 1 year ago
Disagree but this is the good kind of wrong — it is specific enough to be checked.
comment on chromatogram: what the trials say vs what this community says in c/hplc · 144 points · 1 year ago
Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.
comment on what would you tell week-1 you about gradient in c/hplc · 21 points · 1 year ago
No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.
comment on [Question] New Zealand — has anyone got a straight answer on VendorInvestigate in c/vendorvetting · 16 points · 2 years ago
SWB order #7, New Zealand, no drama, receipts inside
comment on stalled for 24 weeks at 7.5mg and I refuse to panic this time in c/hplc · 154 points · 2 years ago
Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.
comment on [Discussion] testing is doing more work than we give it credit for in c/vendorvetting · 528 points · 2 years ago
Correct. The batch number is load-bearing information, not optional.
comment on unpopular opinion: reship is massively overrated in c/vendorvetting · 22 points · 2 years ago
Correct. The batch number is load-bearing information, not optional.
comment on the Janoshik question that gets asked weekly, answered properly in c/vendorvetting · -27 points · 2 years ago
one vendor per post, multi-vendor goes in the monthly thread
comment on [Results] 87 weeks, 36kg, and purity was the hard part in c/hplc · 69 points · 2 years ago
Strongly agree. Largest single impurity tells a different story than total purity.
