About Sermorelin

Sermorelin is a growth-hormone-releasing hormone analogue.

Previously FDA-approved (Geref, since discontinued). Now dispensed by compounding pharmacies on prescription.

Units per 1 mg of Sermorelin

How many units on a U-100 syringe hold 1 mg, for each vial size and water volume. 1 mg is a round reference amount for scaling, not a dose: multiply or divide to match the dose on your prescription, or use the calculator.

Questions

How do I calculate Sermorelin units on a syringe?

Divide the mg in the vial by the mL of water added to get mg/mL. Divide your prescribed dose by that figure for mL, then multiply by 100 for units on a U-100 syringe. For example, a 3 mg vial with 2 mL of water is 1.5 mg/mL, so every 10 units holds 0.15 mg (150 mcg).

How many units is 1 mg of Sermorelin?

It depends on the vial size and the water added. With a 3 mg vial, 1 mg is 33.33 units after 1 mL of water, 66.67 units after 2 mL of water, 100 units after 3 mL of water. The lookup table above covers the other vial sizes.

Is Sermorelin measured in mg or mcg?

Sermorelin vials are labelled in mg. If your prescription is written in mcg, divide by 1,000 to get mg, or switch the dose field to mcg. In a 3 mg vial mixed with 2 mL, one unit on the syringe holds 0.015 mg (15 mcg).

How much bacteriostatic water do I add to Sermorelin?

Follow the amount on your pharmacy label. The volume of water does not change how much Sermorelin is in the vial; it only changes how many units a given dose takes up. Enter whatever amount was actually added.

What Sermorelin dose should I enter?

The dose written on your prescription. This page converts a dose into syringe units and does not recommend one.
