Hey bro, GH alone isn't going to produce huge muscle gains the way AAS will or the way GH and AAS will. You want to combine it with AAS. As for which AAS, Test should be the base of your cycles. If you have had issues with acne, there are ways to fix that. If you want to use gear, I would figure out how to control acne. First thing is dose. You can get a good effect using a low dose of test. Side effects get worse, the more of a drug you use. So if you can figure out how to use 250mg of test and not break out, you are in good shape. You can build cycles around that, adding other "low acne" drugs into your cycle, while using test as a base.
An accutane cycle can fix ance problems long term, changing the amount of oil you produce. It might be worth while looking into this. Visit your Drem or I believe you can buy it online through Naps. If you buy it online, do a lot of research so you understand how powerful of a drug it is and know how to stay safe. I would use it at a low dose and get blood work done, if not through your Dr, through a private lab online.
Then you can always add some var into your cycle if you like. Otherwise, you can do short var cycles through your GH program.
