MOD-GRF (1-29) peptide calculator
A 2 mg MOD-GRF (1-29) vial mixed with 2 ml of bacteriostatic water holds 1 mg/ml. A 100 mcg dose is 0.10 ml — 10 units on a U-100 insulin syringe — and the vial holds 20 doses of that size.
MOD-GRF (1-29) dosage chart: units to draw
Units on a U-100 insulin syringe (100 units = 1 ml) for MOD-GRF (1-29) doses from 50 mcg to 200 mcg, by how much bacteriostatic water is in a 2 mg vial. The highlighted row is the 100 mcg dose used above.
| Dose | 1 ml water 2 mg/ml | 2 ml water 1 mg/ml | 3 ml water 0.667 mg/ml | Doses per vial |
|---|---|---|---|---|
| 50 mcg | 2.5 u 0.025 ml | 5 u 0.050 ml | 7.5 u 0.075 ml | 40 |
| 100 mcg | 5 u 0.050 ml | 10 u 0.10 ml | 15 u 0.15 ml | 20 |
| 150 mcg | 7.5 u 0.075 ml | 15 u 0.15 ml | 23 u 0.23 ml | 13 |
| 200 mcg | 10 u 0.10 ml | 20 u 0.20 ml | 30 u 0.30 ml | 10 |
A 10-unit draw fits comfortably on a 0.3 ml insulin syringe (30-unit capacity), whose 1-unit (often half-unit) markings are easier to read than the 2-unit ticks on a 1 ml syringe.
Unit math only, not a dosing recommendation. The dose range is what published protocols and trials describe; see the MOD-GRF (1-29) guide for sources.
How to reconstitute MOD-GRF (1-29)
- Wipe both vial stoppers with a fresh alcohol swab and let them dry.
- Draw 2 ml of bacteriostatic water into a syringe.
- Insert the needle at an angle into the MOD-GRF (1-29) vial and let the water run slowly down the inner wall — do not inject directly onto the powder.
- Do not shake. Gently swirl the vial until the peptide fully dissolves.
- Storage for MOD-GRF (1-29): Lyophilized: refrigerated. Reconstituted: refrigerated, use within 14–28 days.
- For a 100 mcg dose, draw to the 10-unit mark (0.10 ml) on a U-100 insulin syringe.
About MOD-GRF (1-29)
MOD-GRF (1-29), also sold as CJC-1295 without DAC, is a stabilized analog of the first 29 amino acids of human GHRH. Commonly supplied as 2 mg lyophilized vials, it produces a short, pulsatile GH release (half-life ~30 minutes) and is typically paired with a GHRP like Ipamorelin. Unlike CJC-1295 with DAC, it preserves natural GH pulsatility rather than elevating baseline GHRH tone.
Half-life: Approximately 30 minutes
Typical dose range: 100 mcg per injection, 1–3x daily (often pre-bed and/or post-workout)
Class: GHRH analog (short-acting)
Regulatory status: Not FDA approved. Research use only in the US.

MOD-GRF (1-29) calculator FAQ
Is this a MOD-GRF (1-29) peptide calculator or a reconstitution calculator?
Both. This MOD-GRF (1-29) calculator converts vial strength, bacteriostatic-water volume, and target dose into milliliters and insulin-syringe units. It does not recommend a medical dose.
How much bacteriostatic water for a 2 mg MOD-GRF (1-29) vial?
This page is pre-filled with 2 ml of bacteriostatic water for a 2 mg MOD-GRF (1-29) vial because that is a common research ratio. You can adjust the water amount in the full calculator.
How many units is a 100 mcg MOD-GRF (1-29) dose?
10 units on a U-100 insulin syringe, when a 2 mg vial is mixed with 2 ml of bacteriostatic water (1 mg/ml). That is 0.10 ml. With a different amount of water the unit count changes — the dose chart on this page lists 1 ml, 2 ml, 3 ml mixes.
How many doses are in a 2 mg MOD-GRF (1-29) vial?
20 doses of 100 mcg. The number of doses depends only on vial strength and dose size — adding more or less water changes the volume of each draw, not how many draws the vial holds.
Does this MOD-GRF (1-29) dosage calculator give medical advice?
No. It only performs unit math. Dosing, titration, and whether MOD-GRF (1-29) is appropriate are clinical decisions that should be made with a licensed healthcare professional.
