HGH 191AA Dosing Protocol: 10 IU Vial — Daily Dosing Schedule & Supplies
Recombinant human growth hormone (HGH 191AA) dosing guide for the 10 IU compounded vial, with concentration calculations and reconstitution steps.
Quickstart highlights
Recombinant human growth hormone (somatropin, 191 amino acids) is identical to endogenous pituitary GH.
Concentration: 10 IU/mL (10 IU vial + 1 mL bacteriostatic water).
At 10 IU/mL: 1 IU = 10 units, 2 IU = 20 units, 4 IU = 40 units on a U-100 syringe.
One 10 IU vial provides 10 daily doses at 1 IU or 2.5 doses at 4 IU daily.
Monitor fasting glucose weekly at doses ≥2 IU/day — HGH causes dose-dependent insulin resistance.
WADA-prohibited in sport; not approved for off-label wellness use by FDA.

Cycle progress
Reconstitution steps
Draw 1 mL bacteriostatic water into a 3 mL syringe; inject slowly down the vial wall — do not inject directly onto the lyophilized pellet.
Allow to dissolve naturally (do not shake); gently swirl if needed — 1–3 minutes.
Final concentration: 10 IU/mL. At this concentration, 1 IU = 10 units on a U-100 syringe.
Label with date and concentration; refrigerate at 2–8 °C immediately. Use within 28 days.

Protocol overview & cycle notes
Achieve GH-mediated body composition improvements (fat loss, lean mass gain) and anti-aging effects through precisely dosed daily subcutaneous HGH injections, starting at 1 IU and titrating based on IGF-1 response and glucose tolerance.
Cycle length: 16 weeks on.
Off-cycle: 4–8 weeks off per cycle; check IGF-1 and fasting glucose before resuming.
Storage & handling
Injection & tracking tips
Inject subcutaneously on an empty stomach in the morning (pre-breakfast) for optimal GH/lipolysis synergy; alternatively, inject in the evening 2+ hours after last meal.
Use a short, fine-gauge needle: 29G–31G, 4–6 mm length for subcutaneous abdominal injection.
NEVER inject into a vein — strictly subcutaneous administration only.
Tracking
Logging helps you and your provider spot patterns and adjust dose or timing.
Check fasting glucose weekly for the first 8 weeks — HGH causes insulin resistance at doses ≥2 IU/day.
Measure IGF-1 at baseline and every 4 weeks — target upper-normal range for age (<250 ng/mL for adults over 40).
Track body composition (lean mass, body fat %) via InBody or DEXA every 8 weeks.
