Testosterone cypionate a generic name for TEC Sachet is the most popular and most used testosterone. Testosterone Cypionate, like enatanthe, is an oil-dissolved injectable form of testosterone with strong androgenic and anabolic effects. TEC aromatizes quite easily which means that the conversion rate to estrogen, similar to enanthate's, is relatively high. Several athletes are of the opinion that Testosterone cypionate stores more water in the body than Testosterone enantathe does. The muscle buildup during the application along with the inevitable loss of strength and muscle mass after discontinuing use of one product, are the same with the other. Testosterone cypionate can be combined with many anabolic steroids and thus making it an excellent mass steroid. As with Testosterone enanthate the dosage range is 250-1000 mg/week although several athletes inject megadoses.
