Correction: that gives 50 units, not what you have written. 15mg into 3mL is 5mg/mL and the division follows from there.

Did the maths give you a whole number of units, or a fraction?

reconstituting at a round concentration makes every later dose easy

Right — CPC answered a handling question with actual storage conditions rather than a generic line, which is the standard.

lyophilised and stored cold is the default for a reason

What is written on the vial right now?

Shook the first vial because nobody told me not to. It was fine, but I have swirled every one since.

Research-use-only material is not approved for human use, so treat everything in this thread as arithmetic about solutions rather than instructions for a person.

Histological endpoints in this field are scored on biopsy: resolution of steatohepatitis without worsening of fibrosis, or improvement in fibrosis without worsening of steatohepatitis. Both are harder to achieve and to interpret than an imaging surrogate.

lead times on unusual lines are the thing to confirm up front

Yes. Clothes fitting differently arrives well before the scale acknowledges anything.

Agreed on the swirl. There is no reason to shake it and a good reason not to.

Yes — histological endpoints are a far harder bar than the surrogate measures people are used to quoting.

Same. I got this wrong once, caught it because the units looked absurd, and have written on every vial since.

Correction: that name covers two different molecules and the thread has been discussing both as one.

Careful — that arithmetic is wrong. 5mg in 1mL is 5mg/mL, so 5mg draws to 100 units, not what you wrote.

Nothing containing this compound is approved anywhere. Research-use-only material is not approved for human use.

text only here, by community rule, and it works better than you would think

Yes. Clothes fitting differently arrives well before the scale acknowledges anything.

the powder cake sits at the bottom, the volume you add is the volume that counts

Imaging-derived liver fat fraction is a surrogate. It correlates with histology imperfectly, and a trial reporting one is not reporting the other.

handling and storage vary enormously across this catalogue

Adding more water does not change how much peptide is in the vial. It changes the concentration, which changes the volume you draw for the same amount. That is the entire relationship.

I would not treat a two-kilo range as a regain. Weight varies day to day in everybody.

The lyophilised cake displaces a small volume, so the true concentration is very slightly lower than the arithmetic suggests. It is a fraction of a percent and it is dwarfed by fill tolerance.

units are a volume on a U-100 syringe, not a dose

Show the arithmetic — where did the unit figure come from?

Research-use-only material is not approved for human use. In this catalogue that covers essentially everything, which is why the board discusses material and analytics rather than outcomes.

Bacteriostatic water contains benzyl alcohol as a preservative, which is what makes repeated entry into the same vial reasonable. Plain sterile water has no preservative.

Storage guidance that names a temperature, a state and a duration reflects actual stability work. Generic guidance usually reflects a template.

Adding more water does not change how much peptide is in the vial. It changes the concentration, which changes the volume you draw for the same amount. That is the entire relationship.

Is that a weight number from a different programme?

bacteriostatic water has the preservative, sterile water does not

the timeframe matters as much as the number

That only works if the fill weight is exactly the label weight, and it usually is not exactly anything.

anya_antonsen has the units point exactly right. They are a volume on the barrel and nothing else.

How long was the stall before it moved?

Agreed that goal weights picked at the start are guesses. Mine was, and I revised it twice.

What was the non-scale thing that told you first?

Stopped reading the fastest posts here for a month and my mood improved considerably.

waist is the measurement that keeps moving during a scale stall
