The related substances profile is way more interesting than the main peak %. A 98% with 4 peaks is different from a 98% that is one 8% impurity.

pentadecapeptide is sequence, the supply chain naming is a mess
comment on regulatory is the most under-discussed thing in c/meta in c/bpc157 · 7 points · 2 months ago
That is net peptide content, not purity. Different number, different meaning.
comment on what would you tell week-1 you about HPLC in c/hplc · 102 points · 2 months ago
Gradient goblin mode: changed the solvent composition 4 times, finally got good resolution on a LC-MS peak.
comment on cloned site vs fake COA — genuinely asking which matters more in c/scamalerts · 26 points · 2 months ago
fake COAs always have the same tell: perfect results, zero variance

no cycle-tracking data with identifying details

Week 8 for me and the honest summary is: 6kg down, fatigue manageable, and I have thought about food maybe four times today.

Maintenance for 15 months now. Weight moves within about 3kg and the dose is a quarter of what it peaked at.

a dispute resolves, edit the post and say so
comment on [Lab] SGN cagri — VendorInvestigate came back 93.7% against a claimed 98.6% in c/hplc · 277 points · 2 months ago
Yeah, the chromatogram profile matters more than the headline number.
comment on integration vs purity — genuinely asking which matters more in c/hplc · 1 points · 3 months ago
state the method: column, gradient, detection wavelength, injection volume
comment on [Results] 87 weeks, 11kg, and interval stretching was the hard part in c/tapering · 11 points · 3 months ago
Sceptical. If this were true we would see it reflected in the data and we do not.
comment on help me understand fake COA, I have read the wiki twice in c/scamalerts · 13 points · 3 months ago
Can you post the Medutest result that shows the problem?
comment on the HPLC thing finally clicked for me and I want to write it down in c/hplc · 1 points · 4 months ago
Gradient goblin mode: changed the solvent composition 5 times, finally got good resolution on a chromatogram peak.
Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

I am going to push back on this slightly.
comment on someone explain HPLC to me like I have not read a paper in years in c/hplc · 9 points · 4 months ago
instrument quality is less important than analyst consistency
comment on [Meta] the cycle rule is doing its job and people should stop complaining in c/glp1women · 4 points · 5 months ago

Yes, exactly this, and it is the bit that took me 12 weeks to accept.
comment on PCOS — my 11-week log, condensed into one table in c/glp1women · 37 points · 6 months ago
How many weeks between the two measurements?
comment on the integration question that gets asked weekly, answered properly in c/hplc · 8 points · 7 months ago
axis labels included, always
comment on someone explain regain to me like I have not read a paper in years in c/tapering · 26 points · 7 months ago
interval stretching versus dose reduction
Adding to this: tapering is doing more work than the comment implies.
