There's a lot to be said for proper PCT and all that when it comes to recovery, but it's of utmost importance to get regular blood tests (before, after and on cycle) and learn your own body. This is the main reason that it's best to only run test on your first cycle. If you go blasting yourself with a bunch of compounds right out of the gate and something starts going awry, it can be very difficult to pinpoint the problem since you have no idea how your body reacts to the compounds individually. This also goes for shutdown/suppression of the HPTA. If you know that one compound really shuts you down hard and keeps your natural levels low for a while, you can avoid it in the future if you like.
As a non-aromatizing androgen, dihydrotestosterone is extremely potent. Aromatization refers to the conversion of testosterone or anabolic steroids into estrogen. High estrogenic activity causes bloating, acne, water retention and oily skin. As dihydrotestosterone does not aromatize even at high dosages, users do not face the aforementioned side-effects. Lack of water retention also has a hardening effect on muscle tissue, in bodybuilders. Being a powerful androgen, dihydrotestosterone is also responsible for a shift in the estrogen-testosterone ratio in the body. Due to its predominant androgenic component, the steroid has a stimulating effect on the adreno-pituitary functions, and causes neurological excitation in the ‘sexual orientation areas of the brain’. This in turn, spikes sex drive in males.
