I have two major issues with this, and I'm just going to come right out and say them so maybe you have some undestanding as to why you're not getting very much positive feedback.
1. You're 18, this is pretty self explanatory... But i've seen 18 year olds get good feedback from the board so long as they don't do what you did. Which is number 2.
2. You started a cycle without doing any research at all it seems like. your "guy" most likely just wants to make sales and doesn't give a flying fish about your health. You came on here for guidance, which is fine. But you should have done it BEFORE you started your cycle. To come on here and ask about "tweaking" your cycle and post cycle therapy (pct) after you've already started makes no sense at all. These are things that need to be finalized before you take that first injection. This is where DISCIPLINE comes in to play. Sure, you can be committed to something at 18... But you clearly lacked the DISCIPLINE to hold off until you had a cycle nailed down.
All that being said... Stick around, read the stickies and the older posts. All of the information you seek is in there. The guys on here are great and have tons of valuable information. So long as you follow the rules and are smart about things like AAS, you will fit right in.
