This is correct. The co-agonism is real.
comment on [Explainer] area% is not mass% and here is exactly why it matters in c/coa · 2 points · 5 days ago
Water content was 3.8%, acetate was 6.2%, purity was 99%, but net peptide was only 90% of the label weight. Perfectly honest, just chemistry.

confirmations are network, the exchange rate at 2 blocks is the deal

Sent one vial to PeptideMeter and VendorInvestigate. 98.4% and 98.1%. Cost me more than the vial did and I would do it again.

comment on [Question] resting heart rate up 7bpm, week 6, is that a thing in c/sideeffects · 1 points · 6 days ago
How many weeks in are you? 3 weeks is noise, 8 weeks is a trend.
comment on bought a second-hand HPLC. worst best decision of my life. AMA in c/hplc · 1 points · 9 days ago
Titration speed is a side-effect dial far more than an efficacy dial.
Adding to this: method development is doing more work than the comment implies.
comment on [Question] why does the satiety feel qualitatively different in c/cagrilintide · 1 points · 9 days ago
The research community is small on cagrilintide. Forum lore changes faster than data.
comment on [Results] 61 weeks, 34kg, one very boring spreadsheet in c/semaglutide · 12 points · 12 days ago
the 2.4mg dose is not the target, it is just what the pen goes up to

chromatogram or it did not happen
comment on [Discussion] restarting is not failing and we should say that louder in c/tapering · 84 points · 14 days ago
This is correct. Discontinuation data is real.
comment on [Question] how long were you on before you tapered in c/tapering · 27 points · 17 days ago
Genuine question — what concentration were you at?
Adding to this: regain is doing more work than the comment implies.

the GIP side does different things than the GLP-1 side, that is the point

comment on stalled for 14 weeks at 5mg and I refuse to panic this time in c/sideeffects · -34 points · 1 months ago
hair loss is real and usually reversible when you stabilize
Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
comment on anyone else notice water content kicking in around week 50 in c/coa · 6 points · 1 months ago

comment on does gradient actually matter or is it forum lore at this point in c/hplc · 19 points · 1 months ago
axis labels included, always
comment on stalled for 7 weeks at 7.5mg and I refuse to panic this time in c/sideeffects · 69 points · 1 months ago
hair loss is real and usually reversible when you stabilize
