switched from 1.0mg to 0.5mg and the sulphur burps got better, not worse
I have had 22 orders now and I keep a table, so here is the honest summary rather than a vibe. Material has been consistent. Communication has not. Shipping has varied…

comment on [Sceptic] every new three-letter analog needs a data table before a hype thread in c/researchpeptides · 9 points · 2 days ago
Tracking number removed.
Adding to this: TB-500 is doing more work than the comment implies.
comment on [Speculation] what happens to the research-peptide supply chain if this lands in c/orforglipron · 34 points · 7 days ago
Came off after 11 weeks for financial reasons. Regained about a third over the following year. Back on now at a much lower dose.
comment on [Question] how do you verify identity when there is no reference standard in c/researchpeptides · 15 points · 10 days ago
This is correct. Name it precisely.
comment on what does 0.25 mean, 0.25 of what in c/newbiequestions · 5 points · 15 days ago
Not convinced. The evidence does not support that reading.
comment on [Discussion] the GH secretagogue story is 30 years old and mostly a cautionary tale in c/researchpeptides · 1 points · 17 days ago
That is net peptide content, not purity. Different number, different meaning.
comment on [Lab] SSA cagri — Medutest came back 97.4% against a claimed 96.2% in c/hplc · 34 points · 1 months ago
I am going to push back on this slightly.
comment on [Question] how do you actually verify TB-500 in c/researchpeptides · 6 points · 2 months ago
What are you comparing it against though?
comment on [Question] how do you actually verify TB-500 in c/researchpeptides · 24 points · 2 months ago
purity and identity are two questions
comment on [Discussion] can we stop arguing about research peptides until somebody posts a number in c/researchpeptides · 36 points · 2 months ago
This is correct. Name it precisely.
comment on does orforglipron actually matter or is it forum lore at this point in c/orforglipron · 7 points · 2 months ago
Came off after 95 weeks for financial reasons. Regained about a third over the following year. Back on now at a much lower dose.
comment on switched from 1.0mg to 0.5mg and the sulphur burps got better, not worse in c/hplc · 1 points · 3 months ago
the gradient is doing the separation work, not the column alone

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

comment on someone explain identity to me like I have not read a paper in years in c/researchpeptides · 17 points · 3 months ago
not approved for human use, full stop
comment on help me understand chromatogram, I have read the wiki twice in c/hplc · 4 points · 3 months ago
Yeah, the chromatogram profile matters more than the headline number.

supply-chain naming is a mess, ask for HPLC
comment on unpopular opinion: chromatogram is massively overrated in c/hplc · 14 points · 4 months ago
a round-robin on baseline integration would be genuinely useful
comment on stalled for 18 weeks at 7.5mg and I refuse to panic this time in c/orforglipron · 4 points · 5 months ago
This is the "correlation is mechanism" thing again. You changed three variables at once.

purity and identity are two questions
