The prime advantage of this product is the fact that Testosterone Cypionate can be injected once per week and it gives some very good gains in strength and size. I would bet that many careers testonon in bodybuilding and athletics were built with the long term use of this drug. I’ve used it at doses of 250-2,000 mg per week, and found that the best gains versus side effects are probably had somewhere below the 750 mg/week mark. Of course this is far below what many competitors in the upper ranks of bodybuilding use, but for the average (recreational) bodybuilder or athlete, the side effects above this dose do not constitute an acceptable trade off for the gains.
From all the forms of steroids that are available in the market you will find that there are a large number of steroids that are available in the both oral as well as injectable form. While comparing the oral and injectable form, more stability with some quality gains would be achieved by using injectable form of the steroids. But there are some higher amount of side effects associated with the injectable form. The first thing is that the user must not make any mistake while administrating the injectable form of steroid in the body. There are some anabolic androgenic steroids that are not available in both forms while there are some whose oral form is less effective than the injectable form and vice versa. Some of these steroids are being discussed here.
