Injected testosterone should be used with ALL cycles. Other steroids shut down your natural testosterone, so you need to supplement to make up the difference or you'll get boner problems. If you wanna use Winny, you need to use Winny and test. Also run an AI on cycle (Arimidex or Aromasin) and HCG. Also have Clomid and Nolvadex for PCT when you're done.

Have used yet, but that's what they all say. Hope to start soon.

Also make sure you're done growing because steroids will stop your growth (height-wise)
