Recombinant human growth hormone.
Somatropin is recombinant 191-amino-acid human growth hormone, identical to the pituitary form. Studied for body composition, recovery, skin and longevity.
Subcutaneous, daily — morning fasted or pre-bed. 3–6 month cycles common.
1–4 IU per day for adult research; titrate up slowly.
10 IU vial + 1 mL BAC water = 10 IU/mL (0.1 mL = 1 IU). Refrigerate.
Always use bacteriostatic water (BAC), sterile technique and store reconstituted vials refrigerated unless otherwise noted.
