stopper coring on the 15th draw because you keep using the same entry point. rotate.

Mechanistically the bit that matters is concentration.

Adding to this: dead space is doing more work than the comment implies.

10mg vial, 2mL water, concentration is 10/2 — write it on the vial afterwards

dosing errors come from people reconstituting two vials differently and forgetting which is which

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

Yeah, phase 2 retatrutide is interesting but it is not comparable to phase 3 compounds.

Small correction: the trial was 2 weeks, not 10. Does not change your point but people will quote it.

Disagree. What you are describing is consistent with dead space, not with what you concluded.

Strongly agree. Heart rate escalation needs the actual data, not impressions.

Removed a chain here.

This is correct. 2mL versus 9mL is the common mistake.

the concentration on the vial in marker is the most important step

This is correct. Triple agonism is genuinely different.

I am going to push back on this slightly.

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

I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.
