win/test

hello guys, im as green as they get with steroids so i have a few questions. First i want to state that as i am only 18 and have plenty of gains to make in my training naturally i am not even considering using for a few years. My friend is starting a 10 week cycle of win/test Im not sure on the amounts but in general is this a good combo?? hes already pretty big 5’9" 250lbs fairly low bf% and says hes going to gain some weight a lean up. He said he paid 500 bucks for it, is that normal for a 10 week cycle?? i realise i dont have amounts but in general? Finally i was wondering if anyone knew any good sites/resources/articles for the basics of steroids ie what each drug does, amounts used, side effects how to cylcle etc etc. Thanks guys
