Protropin is a synthetic (man-made) version of human growth hormone (HGH), a naturally occurring substance thats produced by the pituitary gland which primarily stimulates growth in children. Protropin is approved for use in children who have certain conditions which restrict normal growth and development, such as a growth hormone deficiency due to reduced natural HGH production, kidney disease, Prader-Willi Syndrome (PWS), and Turner's syndrome. Protropin was most often used in adults to treat both growth failure and weight loss caused by acquired immunodeficiency syndrome (AIDS).
As of late, synthetic HGH in general has taken on yet another role, that of a modern day Fountain of Youth. Its multi-faceted cell restorative and revitalizing properties have spurred many clinics to market HGH as an anti-aging hormone.
Protropin is a sterile, white, lyophilized powder intended for subcutaneous injection after reconstitution with Bacteriostatic Water. It comes in a 5 mg Protropin vial containing 5 mg (approximately 15 IU) of somatrem, lyophilized with 40 mg of mannitol, and 1.7 mg of sodium phosphates (0.1 mg sodium phosphatemonobasic and 1.6 mg sodium phosphate dibasic). Each 10 mg Protropin vial contains 10 mg (approximately 30 IU) somatrem, lyophilized with 80 mg mannitol, and 3.4 mg sodium phosphates (0.2 mg sodium phosphate monobasic and 3.2 mg sodium phosphate dibasic).
Bacteriostatic Water for Injection is sterile water containing 0.9 percent benzyl alcohol per ml as an antimicrobial preservative, thats also packaged in a multi-dose vial. Phosphoric acid may be used for pH adjustment.
For bodybuilding/athletic purposes Protropin is used to stimulate the growth and skeletal muscle, and for the strengthening of connective tissue. It also contributes the metabolism of macronutrients (fats, carbohydrates and proteins), as well as individual vitamins, minerals and lipids. It can be effectively used as a stand-alone product, or run concurrently during both bulking and cutting cycles.
Initial adult therapeutic dosing is based on body weight, and is typically 0.005 mg per kilogram (0.0023 mg per pound) of body weight once a day, after which increases are made as necessary. Bodybuilders and athletes generally administer performance enhancement dosages ranging from 1 to 6 IU/day, among which 2-4 IU is average, for 3 months to an indefinite amount of time.
Among Protropins common side effects are: abnormal or decreased touch sensation; blurred vision; burning, crawling, itching, numbness, prickling, "pins and needles", or tingling feelings; dizziness; ear infection or other ear problems (in patients with Turner's syndrome); nervousness; pounding in the ears; severe headaches; irregularly fast or slow heartbeat; early onset carpal tunnel syndrome and; gynecomastia.
Its rare side effects include: abdominal pain or bloating; actual changes in vision; depression of skin at place of injection; limp; nausea and vomiting; pain and swelling at place of injection; pain in hip or knee and; skin rash or itching.
The Chinese versions of synthetic HGH are usually less expensive, but also of poorer quality.
Protropins anabolic effects can be easily augmented by athletes and bodybuilders by adding it to anabolic steroid cycles comprised of compounds like Halotestin, Stanozolol, Oral Turinabol, Deca-Durabolin, Primobolan, testosterone (cypionate, propionate, and enanthate), Anavar, and Trenbolone.
