How much BAC water to add to a 24 mg Reta vial for 4 mg weekly dosing?

Participants recommend adding 2.4 ml of BAC water to a 24 mg vial so that 10 units on a 1 ml syringe delivers 1 mg. One user notes their own vial tested at only 22 mg on the COA rather than the labeled amount. Several point to online peptide calculators as the easiest way to handle the math, while others stress checking actual content first.

What this discussion establishesWhere people disagree

Whether the vial actually contains the full 24 mg or less

Nothing here is advice.

I already know the basic steps for mixing but my question is narrower. With a 24 mg vial of the lyophilized product, how much BAC water do I need to reach a 4 mg weekly dose? Any guide I can look at?

Plenty of peptide calculators are available that will work out the numbers for you.

If the vial really holds 24 mg, did you check the COA for the actual amount? Mine came back at 22 mg. I would go with 2.4 ml.

The simplest approach is to add 2.4 ml of BAC to the 24 mg vial so each 10 units on the syringe equals 1 mg.

I find it hard to understand how someone can locate the product and BAC water yet miss a peptide calculator. This area is getting busy.

This assumes you have a 3 ml syringe for mixing and are using 1 ml syringes for the shots.

Thanks for the link, there was plenty of detail there on which peptides cannot be mixed that I had not seen before.
