No man, i would suggest for you to not touch steroids.
First you have no idea what you are doing. You need to do some research. You cannot do a cycle of steroids without doing a proper PCT in order to get your balls up and running again. You didnt even mention a Post Cycle Therapy so do a lot of research on that.
Next, you dont run Letro on cycle, it will lower your estrogen way too much and you need estrogen for your body to function and build muscle properly. Again you should know this if you are fucking with steroids. I would suggest you look into Aromasin or arimidex for on cycle.
3rd, do you even lift?(Not joking) Alot of people want to jump right into steroids the minute they start working out. they forget that you need experience and knowledge in the gym. Diet and training are the most important aspects when it comes to getting big.
If you havent been lifting seriously for atleast 1-2 years and have your diet and training regime down packed, taking steroids will just be a waste of your time.
So if you do have alot of experience in the gym, thats good, but your still not ready for steroids. You got a lot of research to do my man.
