How do calcalculate dosage after reconstituting?

[0bserver]

You've been taking 9.6 mg of retatrutide per week.

It sounds like you're living dangerously by not understanding reconstitution math and calculators.

Where did you buy your retatrutide, and what are you using for water?

Your not wrong. That concern is what brought me to these forums.

I got the peptides from a local friend of a friend that works in the medical field. I was given bacteriostatic water to reconstitute with.

Damn all these calculators, learn the math, it's not complicated and it radically reduces your chances of getting the calculator wrong.

Dimensional Analysis is a wonderful and under-taught basic skill.

Weight divided by volume= weight/volume

Weight/volume * volume= weight

20mg/2.5ml= 8mg/ml

8mg/ml*.3ml= 2.4mg

Or simply

20mg/2.5ml*.3ml= 2.4mg.

Weight of the vial, divided by the volume of fluid into the vial, times the volume of the measured dose equals the weight of the measured dose. Dividing by volume and multiplying by volume cancels out, leaving weight as the only unit remaining to go with the answer.

It works forwards or backwards. Yesterday I wanted to recon a 30mg vial to give a 5mg in a .20ml draw.

5mg/.20ml= 25mg/ml

30mg/ 25mg/ml= 1.2ml

Thus recon with 1.2ml, and a 5mg dose is .2ml

25mg/ml*.2ml=5mg

Thank you . I am data driven this is the insight I needed

If you are not confident with the maths involved use an online peptide calculator. It is not even close to safe to be using these drugs without knowing for certain what dose you are taking.

Also for 20mg of reta use 2ml not 2.5, much much easier to work out doses and volumes, with nice round numbers, so then 20mg = 2ml ,10mg = 1ml , 1mg = 0.1ml so 3mg = 0.3ml or 30 units. If you write it out just like I just did, it is easy to understand and harder to make mistakes, especially if you are not native to using the metric system.

At the moment you are using 2.5ml for 20mg so 20mg/2.4ml= 8mg / 1ml , 0.8mg = 0.1ml , 2.4mg = 0.3ml or 30 units

Ideally you want to work it out on a piece of paper and online and make sure they match, getting doses wrong by mistake is by far the most common way to make yourself ill with grey peptides.

Ty . This is helpful

Thanks for this. For all the times I've looked at the math, I didn't understand it until now.

I've been relying on online calculators (and like the one I use) but it never sat right that I couldn't figure it out myself. Yes, I lean towards needing to be in control.

I dont know my mg dose. Thats what I am trying to back into. These calculators should help

You have no clue how much you taking? Start fresh with 2mg for 4 weeks, then 4mg and see where you go from there. I personally like 4 weeks because it lets the R build up in your system. You do what ever you though.

Oh great.

Reta 20mg. Add 1ml bac (100 units)...every 10units=2mg. Every 5units=1mg....no need to fill the vial to the neck with bac....before ya know youll be on 8mg so 40units. I add 1ml to r30 so every 10units is 3mg, 5units is 1.5mg.... KISS (keep it simple stupid)

Thank goodness you made it here learn how its done!
