How to reconstitute retatrutide
Three questions and you will have a number to draw to. No sign-up, nothing for sale at the end.
What does your retatrutide vial say?
The number printed on the label, before you mix anything.
What dose are you aiming for?
Your target, not ours. Lovapep does not recommend a dose.
How much water will you add?
This is your choice. It changes nothing about the dose — only how much liquid that dose sits in, and therefore how easy it is to measure.
That is 0.10 mL of liquid.
Lovapep is a tracker and calculator, not medical advice. It reports what your own numbers produce and flags when they look unmeasurable.
Whether a draw “lands on a whole mark” is a statement about the barrel and the arithmetic, not about whether this dose is right for you.
What just happened?
Two divisions. The milligrams in the vial divided by the millilitres of water you added give the concentration. Your target divided by that concentration gives the volume of liquid that holds it. A U-100 syringe barrel runs 0 to 100 units across one millilitre, so that volume, multiplied by a hundred, is the mark you stop at.
The water does not change how much compound you have. It changes how much liquid that compound is spread through, and therefore how far along the barrel your dose lands. More water means a longer, easier-to-read draw. Less water means a shorter one.
Other doses at this mix
At your concentration — 2.50 mg/mL
| Dose | Volume | On a U-100 syringe |
|---|---|---|
| 250 mcg | 0.10 mL | 10 units |
| 500 mcg | 0.20 mL | 20 units |
| 750 mcg | 0.30 mL | 30 units |
