Worried about potential side-effects

[ryangmode]

Hey guys, I have been lifting for a year. I'm 5-9, 176 and have some decent lifts. I ordered the Advanced Muscle Science Anabolic Growth Kit RDe 180 Tablets. This kit is the 1-andro, 4ad, and decavol kit. However, I am worried that I will develop some side effects from a 4 week cycle. The main concern being gyno. I guess the question is, what are the risks of this happening, and what can I do to limit the chances of this happening? I did order some pct known as AD-3 PCT by Lecheek. Also, some suggest an 8 week cycle. What are your recommendations on that?
Also, will it be safe to take stim pre-workout while on cycle? Thanks guys, I really appreciate it!
