HGH reconstitution calculator

How much bacteriostatic water to add to a HGH vial, what concentration that gives, and how many units to draw on a U-100 insulin syringe for your dose.

Vial mass

The total mg of compound in the vial as labelled by the supplier.

Bacteriostatic water

How much sterile bac water you'll add to reconstitute the vial.

Desired single dose

How much of the compound you want to take per injection.

Syringe size

U-100 syringes use the standard 100 units = 1 ml gradation.

Draw on syringe

3 units

Volume to draw

0.030 ml

Concentration

5.00 mg/ml

Doses per vial

66.67 doses

Draw to the 3-unit mark on a 100-unit insulin syringe.

A worked example

Take a 10 mg vial of HGH and the catalogue's typical dose of 330 mcg. Add 3 ml of bacteriostatic water and the vial holds 3.33 mg/ml, so one dose is 9.9 units on a U-100 insulin syringe.

9.9 units = 330 mcg

At once daily over 26 weeks that is 182 doses and 60.06 mg in total — 7 vials of 10 mg. One vial covers about 30 days at that rate, which is longer than the ~28 days a reconstituted peptide keeps in a fridge — a smaller vial wastes less. Storage on record — Lyophilized: Room temperature. Reconstituted: 2-8°C, use within 14-28 days

What the catalogue records

Typical dose: 1-4 IU daily (0.33-1.33mg); start low and titrate up
Frequency: Once daily or split into 2 doses (morning and evening)
Cycle duration: 3-6+ months or ongoing for medical GHD
Half-life: 3-4 hours (SC), 20-30 minutes (IV)
Storage: Lyophilized: Room temperature. Reconstituted: 2-8°C, use within 14-28 days

Mixing a HGH vial

What you need

HGH lyophilized powder vial (typically 10 IU or 36 IU)
Bacteriostatic water for injection
Insulin syringes (29-31 gauge)
Alcohol prep pads

Steps

Allow vial to reach room temperature (15-20 minutes)
Clean rubber stoppers with alcohol swab
Determine reconstitution volume (typical: 1mL BAC water per 10 IU)
Draw bacteriostatic water slowly, removing air bubbles
Insert needle at angle, aiming stream at vial wall - not directly on powder
Inject water slowly down inside wall, drop by drop
Remove needle and gently swirl in circular motion - never shake
Allow to sit if cloudy, then swirl again until crystal clear
Solution must be crystal clear; discard if cloudy or contains particles
Label with reconstitution date and concentration
Store refrigerated at 2-8°C; use within 14-28 days

Where this goes next

HGH — mechanism, dosing and safety — what it is, what the evidence says, and what it interacts with.
Build a cycle around it — the cycle builder runs this same arithmetic across every compound you add and totals the vials.
The general reconstitution calculator — the same tool with nothing prefilled.
