5mg vial + 2mL BAC water = 4 units = 100mcg — Amounts listed in the Dosify Me data: 100-300mcg per injection, once daily or 2-3 times a day — Frequency: once or 2-3x daily — Best taken: morning, fasted

Amounts and schedules here are listed from the Dosify Me compound data (sources below). They are not recommendations: Dosify Me does not tell you what dose to take, so follow your prescriber.
Every vial size below is mixed to the same concentration, 2.5 mg/mL, so the syringe reads the same number of units for a given dose no matter which vial you bought.
| Vial | Bacteriostatic water | Concentration |
|---|---|---|
| 5 mg | 2.00 mL | 2.5 mg/mL |
On a standard 100-unit (1 mL) insulin syringe, at the concentration above:
| Dose | Syringe units |
|---|---|
| 100 mcg | 4.0 units |
| 200 mcg | 8.0 units |
| 300 mcg | 12.0 units |
Amounts listed in the Dosify Me data: 100–300 mcg. Frequency: once or 2-3x daily. Timing: morning, fasted.
All vial sizes reconstitute to 2.5mg/mL (25mcg/unit) so the syringe reads the same regardless of 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.
Check one row of the table above: 100 mcg is 0.1 mg; 0.1 mg ÷ 2.5 mg/mL = 0.04 mL; 0.04 mL × 100 = 4 units.
Anecdotal and early-research reports, kept apart from the evidence above. Not clinically established.
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.

At 2.5 mg/mL (the concentration every vial size mixes to), 100 mcg of GHRP-2 is 4.0 units on a 100-unit insulin syringe (0.040 mL).
At 2.5 mg/mL (the concentration every vial size mixes to), 200 mcg of GHRP-2 is 8.0 units on a 100-unit insulin syringe (0.080 mL).
At 2.5 mg/mL (the concentration every vial size mixes to), 300 mcg of GHRP-2 is 12.0 units on a 100-unit insulin syringe (0.120 mL).
2.00 mL, which gives 2.5 mg/mL. Other vial sizes use proportionally more or less water so the syringe reads the same.
Once or 2-3x daily. Morning, fasted Typical cycle: ~8 weeks on, ~4 weeks off; repeat 2×/year.
Dosify Me does this math for you. Pick the compound, your vial size and dose, and the app draws the exact syringe reading, keeps your schedule and reminders, and logs every dose — privately, on your phone.

Figures come from the Dosify Me compound database for GHRP-2: concentration is the vial amount ÷ the water volume, and syringe units are the volume in mL × 100 on a U-100 syringe.
