First of all we say that you have to have a foundation to be able to start this way of life, that is the use of chemistry. Obviously what I'm saying is just my opinion, any guy can do whatever the fuck he wants, the same will use the gears at any age. The ideal would be to be at least twenty-five years old (I said minimum), unless you're a genetic talent and do you want to compete like most PRO, starting at eighteen/nineteen years old, or you're not an influencer and do you want to live on that (like so many stupid guys who run on YB).

Have a good economic foundation, especially because it is a fairly expensive sport and even more so using chemistry. Expensive because there are some parameters to follow: drugs, periodic health checks, diet, PCT drugs, training, supplements and more. You need knowledge of biochemistry, physiology and biomechanics, because if you do not know how to train and do not know how to eat, yes anabolics help the same and give that extra gear in the gym but the ideal would be to use them when you have already reached your natural limit and want to amplify the results with the use of gears, a good diet and a good workout.

It also takes a good psychological foundation, especially if you don't use it continuously. For example you start a cycle and then do the post-cycle, then stop, recover and then start again. These effects are commonly called "rebound" on a psychological level, i.e. seeing yourself not too big and pumped up again as during the cycle, not having all this strength and euphoria need a very strong mind to endure them. This is why most bodybuilders who enter this world then remain there forever. Usually those who start a cycle or abandon bodybuilding completely because they no longer lo see the super hero that was during the cycle and do not want to put their health on the line or he do the first cycle and continue for life (the more advanced members already know what I mean).

So what is the first cycle for? Listen well, I said what is it for!!!
It is to see how our body reacts to the exogenous introduction of these hormones. Anabolic hormones are always derived from testosterone, which is the "RE" hormone of our body. Before starting a cycle my absolute advice is to have a general medical examination, that is a complete picture of our immune system. Many people negligently do these examinations when they have already done some cycles of steroids discovering that they have some pathologies and blame the anabolics, when they were genetically predisposed and that we actually already had them before.
So before starting a cycle the ideal would be to undergo examinations such as: liver profile, lipid profile, a general profile of the kidneys to see how they are working and hormonal examinations, at least testosterone and estradiol. The latter is very fundamental in our body for many functions. Functions of neurological type, cardiovascular protection and especially in the regulation of libido. It's no use if we take more testosterone than we normally produce and then our fuck in bed doesn't work.
At this point we can start our cycle, only with testosterone. A good compromise would be 500MG per week with long ester, e.g. enanthate or cypionate for a total duration of ten weeks.

I don't want to be boring with this reading, I leave the research of dosages and estrogen control to you. I will never get tired of advising you to perform blood tests before, during and after the cycle. Deepen your research before you decide and remember that this is not a sport but a lifestyle, you cannot imitate it.
