Sermorelin Acetate reconstitution calculator

Sermorelin Acetate at a glance

5mg vial + 2.5mL BAC water = 5 units = 100mcg — Frequency: daily — Best taken: evening or bedtime, fasted

What it does

• Growth hormone-releasing hormone (GHRH) analog — a shorter, earlier-generation relative of CJC-1295.
• Previously FDA-approved (as Geref, since discontinued) for diagnosing growth hormone deficiency in children.
• Well-established mechanism with fairly consistent community dosing, unlike many newer peptides.

Raising growth hormone can unmask previously hidden hypothyroidism and shift how the body converts thyroid hormone — that is documented in hypopituitary patients on growth hormone replacement, not in healthy people using secretagogues, and how often it matters here is unknown. GH also raises blood sugar, working against insulin and other diabetes medications. Talk to your prescribing doctor before combining, especially if you take thyroid or diabetes medication.

Notes

The 5mg reference vial mixes to 2mg/mL. Larger vial size options are capped at ~3mL BAC water instead of diluted further, so they come out more concentrated (fewer units per dose) than this reference size. Community protocols commonly cycle GH-secretagogue peptides like this one — typically 8-12 weeks on followed by 4 weeks off (up to 12 weeks off after higher-dose runs) — since continuous use may reduce pituitary receptor sensitivity over time. This app defaults to daily/ongoing use; whether and when to take a break is a question for your prescriber.

Side Effects

• Injection site pain or redness in ~1 in 6, resolving in 1-2 weeks.
• Headache, flushing, dizziness, or drowsiness — brief.
• Mild nausea after the first doses.
• Rare: vivid dreams, insomnia, joint stiffness, water retention.

Sermorelin Acetate vial sizes and concentrations

Standard water for each Sermorelin Acetate vial size in the Dosify Me data, and the concentration it gives. One unit is 0.01 mL on a U-100 insulin syringe.

^* This size is conventionally mixed more concentrated rather than diluted further — fewer units per dose than smaller vials of this peptide.

Syringe units for the listed quantities, by vial size

Worked example for Sermorelin Acetate

1. The example vial: 10 mg of Sermorelin Acetate, mixed with 3.00 mL of bacteriostatic water.
2. Concentration: 10 mg ÷ 3.00 mL = 3.33 mg/mL.
3. One syringe unit is 0.01 mL, so it holds 3.33 mg/mL × 0.01 mL = 0.033 mg (33.33 mcg).
4. Example quantity: 100 mcg = 0.1 mg.
5. Volume: 0.1 mg ÷ 3.33 mg/mL = 0.03 mL.
6. Syringe reading: 0.03 mL × 100 = 3 units.

Frequently asked

How many units is 100 mcg of Sermorelin Acetate?

At 2 mg/mL (the standard mix for vials up to 5 mg), 100 mcg of Sermorelin Acetate is 5.0 units on a 100-unit insulin syringe (0.050 mL).

How many units is 200 mcg of Sermorelin Acetate?

At 2 mg/mL (the standard mix for vials up to 5 mg), 200 mcg of Sermorelin Acetate is 10.0 units on a 100-unit insulin syringe (0.100 mL).

How many units is 300 mcg of Sermorelin Acetate?

At 2 mg/mL (the standard mix for vials up to 5 mg), 300 mcg of Sermorelin Acetate is 15.0 units on a 100-unit insulin syringe (0.150 mL).

How much bacteriostatic water do I add to a 5 mg vial of Sermorelin Acetate?

2.50 mL, which gives 2 mg/mL. Larger vials hold at most 3 mL of water, so they are mixed more concentrated and need fewer units per dose.

How much bacteriostatic water do I add to a 10 mg vial of Sermorelin Acetate?

3.00 mL, which gives 3.33 mg/mL. This size holds at most 3 mL of water, so it is mixed more concentrated and the same dose is fewer units than from a smaller vial.

How often is Sermorelin Acetate taken?

Daily. Evening or bedtime, fasted Typical cycle: ~8 weeks on, ~4 weeks off; repeat 2×/year.
