Pharmaceutical Name: Testabol Enanthate Chemical name: Testosterone Enanthate Chem. Abstr. Name: 4-androsten-3-one-17beta-ol Molecular Structure: CH26H40O3 Molecular Weight: 400.6 Product Desription: Qualitatively similar to testosterone and its esters in physiologic activity, testosterone enanthate has the advantage of prolonged effect. In hypogonadal males, the effect of a single injection of 250 to 500 mg of testosterone enanthate was observed to be maintained for 2 to 4 weeks, which is 2 to 4 times longer than the effect produced by a comparable dose of testosterone propionate. Presentation: Each 10 ml multidose vial contains 250 mg per ml. Starting in January, 2006, the flip-off tops are beige coloured and have Testabol Enanthate stamped on them. On Testabol Enanthate produced between November, 2005, and January, 2006, the flip-off tops are orange coloured and have Testabol Depot stamped on them. Older vials, before November, 2005, have green coloured generic flip-off tops.
