Sermorelin: What It Is, FDA Status & Reconstitution Math
By James Li, Lead Editor · Updated · Reviewed
Quick answer
Sermorelin is a lab-made fragment of growth-hormone-releasing hormone that was sold as Geref, a brand that is now discontinued, so for a vial you have now the numbers that matter are the milligrams on the label and the milliliters of water you added.
Once you have milligrams on the label and the milliliters of water you added, concentration is those milligrams divided by those milliliters, and a U-100 syringe reads that volume as 100 units per milliliter, so 10 units is 0.1 mL while one milligram is 1,000 micrograms.
Blends
Optional. Extra peptides are added to the vial total.
Waiting on Input
5 mg vial, 2 mL water, 250 mcg. Example only, not a dose.

What is Sermorelin?
Sermorelin is a lab-made piece of growth-hormone-releasing hormone, and the old brand Geref is discontinued.
The calculator uses the milligrams printed on your vial and the milliliters of water you added, and it does not supply a schedule.
What is the FDA status of Sermorelin?
Sermorelin was sold as Geref, and that product is discontinued.
A discontinued brand is not a current dosing guide, so if you have a vial the milligrams on that vial are the number the calculator needs.
How is Sermorelin reconstituted?
Reconstitution means a measured volume of liquid, usually bacteriostatic water, was added to a dry vial of Sermorelin.
Concentration is the milligrams in the vial divided by the milliliters you added, doubling the water cuts the amount in each unit in half, and the calculator uses the volume you report rather than picking one for you.
How do you convert Sermorelin mg to mcg and syringe units?
For Sermorelin, multiply milligrams by 1,000 to get micrograms.
That conversion does not produce a syringe mark, because units measure volume and you still divide the micrograms you want to measure by the micrograms in each milliliter.
How should Sermorelin be stored?
Storage for Sermorelin is on its own label, covering temperature, light, and how long it may be kept after mixing.
An unopened bottle and a mixed vial are not the same case, so if the label is missing ask the pharmacist or clinician who supplied it rather than borrowing a rule from a different product.
Where can I find primary sources on Sermorelin?
For the approval status of Sermorelin, start with Drugs@FDA and the product label on DailyMed.
Those are the places that say whether a named product is approved and what its label claims, and this page does not recap studies or change the calculator because of them.
Unit math
Illustrative arithmetic only. Not a dose. Barrel columns use a U-100 scale, 100 units per mL.
| Vial mg | Water mL | mg/mL | mcg/mL | mcg in 10 units |
|---|---|---|---|---|
| 20 | 2 | 10 | 10,000 | 1,000 |
| 5 | 1 | 5 | 5,000 | 500 |
| 10 | 2 | 5 | 5,000 | 500 |
| mL | 1 mL barrel (U-100 scale) | 0.5 mL barrel (U-100 scale) | 0.3 mL barrel (U-100 scale) |
|---|---|---|---|
| 0.05 | 5 | 5 | 5 |
| 0.1 | 10 | 10 | 10 |
| 0.25 | 25 | 25 | 25 |
| 0.5 | 50 | 50 | 50 (past barrel) |
| 1 | 100 | 100 (past barrel) | 100 (past barrel) |

Whether to start, stop, or continue is a decision for you and your clinician, while this calculator converts the numbers on a label into syringe units.
Is Sermorelin worth it?
Whether to start, stop, or continue is a decision for you and your clinician, while this calculator converts the numbers on a label into syringe units.
When to take Sermorelin?
How and when to take a medicine is between you and your clinician, and here you can convert a labeled strength and a water volume into syringe units.
Is Sermorelin FDA approved?
Sermorelin was sold as Geref, and that product is discontinued.
How do I use the Sermorelin calculator?
Type the milligrams on the vial, the milliliters of water you added, and the amount you want to measure, and the syringe mark updates in the calculator.
