On the black market, enanthate is probably the most commonly found ester of testosterone available. Currently the most popular products include the 200mg/ml Mexican generics from the veterinary firms Brovel and Tornel. Both come packaged in 10 ml vials, and offer excellent value for the amount of steroid included. Loeffler has offered a striking new product recently, a 250mg/ml enanthate in a similarly sized vial. Although not the highest dose of this steroid ever produced, it is certainly the only legitimate product containing 250m1 to be found in a container of this size. Primoteston from Mexico, Testoviron® from Schering in Spain and the French product Testosterone Heptylate Theramex also circulate inside the . as well. Heptylate is not a unique ester of testosterone as described by other writers, as in fact it is simply another word for enanthate. Occasionally amps from other regions surface as well, which is to be expected with this ester as it is more widely produced than any other. The actually number of enanthate products made would be difficult to catalog here, and any comprehensive list would be almost impossible to keep current. The typical US black market price for a single 250mg ampule regardless of manufacturer is usually around $10-15.
A 2006 study determined that 1-testosterone has a high androgenic and anabolic potency even without being metabolized, so it can be characterized as a typical anabolic steroid. 1-Testosterone binds in a manner that is highly selective to the androgen receptor (AR) and has a high potency to stimulate AR-dependent transactivation . In vivo , an equimolar dose of 1-testosterone has the same potency to stimulate the growth of the prostate , the seminal vesicles and the androgen-sensitive levator ani muscle as the reference anabolic steroid testosterone propionate , but, unlike testosterone propionate, 1-testosterone also increases liver weight.
