If you are not in a hurry, then better start off with SARMS in order to get gradual growth. Remember, bodybuilding is about patience, and the faster you get your gains, the easier it is to lose them. Therefore, it is best to start gradually, and use SARMS as a beginning. They are milder than steroids are, but they have no side effects, so it is much easier to cycle them. A good SARM cycle will get you conditioned for an AAS cycle, and you will get much better results. To begin with I would recommend the SARMS triple stack as described here -

Then, for a first time steroid cycle it is best to keep things simple, and do a testosterone solo cycle. It may seem like not much, but if you have never used steroids before, you will be superresponsive to them, and you will get quite amazing results with testosterone. The cycle should look like this:
Weeks 1-12
Testosterone Enanthate - 500 mgs per week split into two injections of 250 mgs during the week.
Aromasin - 10 mgs EOD from the first day of the cycle
Then, after the last pin wait two weeks (during these two weeks it is very recommended to use HCGenerate), and then start the perfect PCT. Remember, the better the PCT, the easier it will be for you to keep the gains and recover natural testosterone production. Here you will find a detailed description of the perfect PCT protocol -

In no case should you be using HCG. It can cause such side effects as suppression and gyno. And the worst of all, is that it will barely do anything for natural testosterone production. It will only mimic the functions of LH and FSH, but it will not actually stimulate them to produce testosterone naturally. Hence, your testosterone levels will increase with HCG use, but once you stop taking it, they will fall again. Hence, it is best to use HCGenerate ES as a good alternative to HCG, is it wil cause no side effects at all, and it will actually stimulate your body to produce testosterone naturally, so you will keep the elevated testosterone levels even after stopping its usage.
