never post a calculation as advice without stating the concentration

Two vials, two different concentrations, forgot which was which, almost made a 2 times error. Now I label everything.

Not to be pedantic but mg/mL and insulin syringe are being used interchangeably and they are not interchangeable in real life.

Which state? Rules vary.

long-acting amylin is co-agonism, different satiety profile

no images, none, not even redacted ones

This is correct. The co-agonism is real.

Slight fix: the number was 96.8, not 96.2. Decimal point, but a fairly consequential one.

dead space is real and the syringe matters

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.

regulatory claims need a citation to the actual rule, not interpretation

Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.

Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.

API transparency is the question that separates good compounders from sketchy ones

the 503A/503B distinction is load-bearing, do not blur it

Strongly agree.

Yes, exactly this, and it is the bit that took me 40 weeks to accept.

503B compounding is different from 503A, different rules, different legality

not approved for human use, full stop

Came off after 9 weeks for financial reasons. Regained about a third over the following year. Back on now at a much lower dose.

The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.
