Retatrutide reconstitution calculator
Retatrutide ships as 5 mg, 10 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg vials of lyophilized powder. Pick the size, type the water volume, read the concentration. The molecular weight is already filled in, so the molar result is there too.

What the numbers mean for Retatrutide
Retatrutide has a molecular weight of 4731.32 g/mol (C221H342N46O68). So 5 mg is about 1.06 micromoles, whatever volume you dissolve it in. At 2.5 mg/mL that is 0.528 mM.
Each vial holds only powder, from 5 mg up to 60 mg, and no diluent. Add bacteriostatic water down the inside of the glass, swirl, and do not shake. The reconstitution guide covers the handling; this page covers the arithmetic.
Common questions
How much water do I add to a 5 mg vial of Retatrutide?
+
Any volume that gives a concentration you can measure easily. 1 mL gives 5 mg/mL, 2 mL gives 2.5 mg/mL, 5 mL gives 1 mg/mL. The peptide amount stays 5 mg whatever you add.
What is the concentration of Retatrutide 5 mg in 2 mL?
+
2.5 mg/mL, which is the same as 2.5 µg/µL. With a molecular weight of 4731.32 g/mol that is 0.528 mM.
Which Retatrutide vial sizes does the calculator cover?
+
The ones we sell: 5 mg, 10 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg. Pick a chip or type any other mass.
Where does the Retatrutide molecular weight come from?
+
The reference value on the product's Specifications tab, 4731.32 g/mol. The observed mass for the vial you receive is on its own lab report, which the QR code on the vial opens.
