Fluticasone propionate is a synthetic (man-made) corticosteroid that is used on the skin (topically). The naturally-occurring corticosteroid is cortisol or hydrocortisone produced by the adrenal gland. Corticosteroids have potent anti-inflammatory actions and also suppress the immune response. Similar drugs include betamethasone dipropionate (Diprolene), clobetasol propionate (Temovate), halobetasol propionate (Ultravate), betamethasone dipropionate (Diprosone), desoximetasone (Topicort), halcinonide (Halog), amcinonide (Cyclocort), triamcinolone acetonide (Kenalog), fluocinolone acetonide (Synalar), hydrocortisone butyrate (Locoid), hydrocortisone valerate (Westcort), and mometasone furoate (Elocon). The FDA approved topical fluticasone propionate in December, 1990.
Underground labs create Testosterone Propionate in numerous approaches. As is in human nature, some producers will look to maximize their profit on the expense of the consumer by employing less expensive oils, significantly less filtration due to lack of sophisticated equipment. To expedit filtration and dissolve reduced high quality raw supplies, some labs use Guaiacol, Benzyl Salicylate, Octyl Salicylate, or Ethyl Oleate – which are damaging to the human body. By employing these methods they are in a position to have a cheaper solution compared to larger high quality competition.
