If you could pick just one, test aside (since anyone with a brain will use test as a base!)
what would you pick? I would have to say either winstrol or EQ for me...
great lean gains, not a lot of sides, etc. personally I avoid super strong androgenic's like Suspension or Anadrol, to me it's pointless being swelled up like a balloon with a moon face. I prefer lean gains that look good.
