Sermorelin reconstitution table
What different amounts of water give you, for each quick-pick vial size. This is arithmetic, not a recommendation: the right amount of water is whatever makes your measurements easy and matches any instructions you were given.
| Vial | Water | Concentration | Per unit (0.01 mL) | Per 10 units (0.1 mL) |
|---|---|---|---|---|
| 5 mg | 1 mL | 5 mg/mL | 50 mcg | 500 mcg |
| 5 mg | 2 mL | 2.5 mg/mL | 25 mcg | 250 mcg |
| 5 mg | 3 mL | 1.67 mg/mL | 16.67 mcg | 167 mcg |
| 10 mg | 1 mL | 10 mg/mL | 100 mcg | 1 mg |
| 10 mg | 2 mL | 5 mg/mL | 50 mcg | 500 mcg |
| 10 mg | 3 mL | 3.33 mg/mL | 33.33 mcg | 333 mcg |
How the math works for Sermorelin
A 5 mg Sermorelin vial holds 5,000 mcg. Mixed with 2 mL of water, that's 5,000 ÷ 2 = 2,500 mcg per mL. One unit on a U-100 syringe is 0.01 mL, so each unit holds 25 mcg. More water spreads the same 5 mg across more units; less water packs it into fewer.
mcg per unit = concentration ÷ 100
Units to draw = amount (mcg) ÷ mcg per unit
What is Sermorelin?
Sermorelin is a synthetic version of the first 29 amino acids of growth-hormone-releasing hormone (GHRH). It works by prompting the pituitary gland to release the body's own growth hormone.
Frequently asked questions
How much water do I add to a 5 mg Sermorelin vial?
There's no single right amount. Less water makes each unit stronger and harder to measure; more water makes each unit weaker and easier to measure. For a 5 mg vial, 1 mL gives 50 mcg per unit, 2 mL gives 25 mcg, and 3 mL gives 16.67 mcg. If your Sermorelin was prescribed, use the amount in your prescription instructions.
How many mcg of Sermorelin are in one unit?
It depends on the vial size and how much water you add: mcg per unit = (mg in the vial × 1,000) ÷ (mL of water × 100). With a 5 mg vial and 2 mL of water, that's 25 mcg per unit on a U-100 syringe.
Is Sermorelin FDA approved?
Published sources disagree on sermorelin's current FDA and compounding status, so it isn't on our FDA status tracker yet. If it was prescribed to you, your prescription label and pharmacist are the authority.
