how old should you be to run Topical Form.?

[brock17cf]

I just turned 18, and next track season am planning a fat loss stack for during the season. I can't take stims, and formestane sounds like it would be great- no water retention, fat loss, strength increases, etc.
Any opinions/alternatives?

My stack is going to prolly look similar to this so far:

CEL Formestane, 1 dose/ day-EOD
Lean Xtreme
Cissus Quadrangularis
Vitamin B complex
Man Vaporize

Thanks for the help!
