I've been researching my first cycle as well for the past few months. Some useful advise that I received was to pay attention to the dates of the threads you are reading. If you are pulling advice given in a thread from 5-10 years ago, you might be getting bad or outdated advice.
I'm obviously no expert, but the most updated information seems to agree on the following:
1) First cycle is best to run test only so you can narrow down the source of side effects, and ramp up gain on subsequent cycles with additional compounds
2) It's a lot easier to fine tune your AI dosage on cycle rather than panic when you get gyno and have to treat it on an emergency basis. Most consider an AI essential.
3) HCG greatly assists with recovery and PCT. You are 24 - are you not concerned about your gonads or the possibility of having kids someday?
