Because the ultimate goal of a steroid cycle is to increase strength and muscle size, the associated spike in estrogen which accompanies steroids such as Testosterone is considered undesirable. In order to disassociate the two effects, two classes of drug are used. Medications such as Nolvadex or Clomid target the estrogen receptors. They make it more difficult for the estrogen to exert it’s influence within the body thus allowing the testosterone to act more freely. The second class is aromatase inhibitors such as Femara. They target the aromatase enzyme itself in order to prevent the production of estrogen in the first place. Sometimes, it’s not always clear which option you should go with or even what the differences are between the two. Lets clear that up a little.
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.
In males with delayed puberty: Various dosage regimens have been used; some call for lower dosages initially with gradual increases as puberty progresses, with or without a decrease to maintenance levels. Other regimens call for higher dosage to induce pubertal changes and lower dosage for maintenance after puberty. The chronological and skeletal ages must be taken into consideration, both in determining the initial dose and in adjusting the dose. Dosage is within the range of 50 to 200 mg every 2 to 4 weeks for a limited duration, for example, 4 to 6 months. X-rays should be taken at appropriate intervals to determine the amount of bone maturation and skeletal development (see INDICATIONS AND USAGE and WARNINGS ).
