500 mg of enanthate has more free based testosterone than 500 mg of cypionate and 500 mg of sustanon has more than either. However, due to the irregular release of sustanon and the need to inject more frequently to take full advantage of the propionate and phenylpropionate esters and thereby make full release of the steroid itself, either enanthate or cypionate will be better choices for the first time user, who will likely want to maintain stable blood levels of the steroid while minimizing injection frequency.
Although Testosterone Enanthate has a period of action longer then few weeks, is used by bodybuilders, power-lifters and athletes. The major priority is the fact that has active chemical substance has a strong androgenic and anabolic effect. This means that any athelte can, by using Testosterone Enanthate, increase its power and weight in minimal time. The fast and considerable increase in weight is correlated with the liquids retained in organism. The weightlifters and power-lifters appreciate very much this quality of the Testosterone Enanthate.

Methatren AKA Oral Tren, Metribolone, Methyltrienolone or R1881 is an ultra potent, non-aromatizable androgen which has also been used as a photo-affinity label for the androgen receptor. It is the 17-methylated derivative of Trenbolone, ‘the meth of tren’ and is a similarly potent anabolic steroid, but with high potential for hepatotoxicity
And last but not the least important moment is proper nutrition and training. Eat a lot of protein, don’t forget about whey protein shake after training and early in the morning. Eat 5-6 times per day with small portions.
An important note on natural testosterone recovery; natural recovery assumes no prior low testosterone condition existed. It also assumes the Hypothalamic-Pituitary-Testicular-Axis (HPTA) was not severely damaged due to improper anabolic steroid use .
