These are my opinions.
1. Your too young to start AS. Give your self more time to train and take advantage of your naturally high test levels.
2. Winny alone for a first cycle wouldn't be my first choice. Also injecting everyday for a newbie. Something like 250 mgs/week of test, I would recommend.
3. Sounds like you may have a little more to learn as far as AS goes so give yourself time.
4. Sounds like you may have had problems with drugs or your temper before so get that under control and don't make excuses for it. Hormones can and do play a role in affecting emotions, good and bad. That along with working with and around alcohol and drunk people on a emotional rollercoaster may be hard if you can't control yourself.
5. It also sounds like your looking for us to tell you to go ahead and do drugs(AS). As some of the vets will tell you it's usually not a one time deal and like any other drugs there is alot of bad that goes with little of the good. This isn't like smoking a little weed, hormones are very powerful and can do damage to your body very easily and the results of the damage may not show up right away. Most people who have done AS have experienced side effects. Whether it be acne, sexual disfunction, depression, mood swings, bitch tits, high BP, etc along with things you can't see or fell that happen inside the body.
