I would say an oral like anadrol or dbol, but testosterone suspension hits me within minutes and I see results that day. For the orals it takes a couple of days. Everyone's chemistry is different. I'd like to see your answers.
Dbol for me. Anadrol doesn't fully hit me around week 4 thatsbwjy I run it forb8 weeks. Week 4 is when I start getting nasty back pumps im on superdrol right now and its taking its time
I used to love sublingual Methyltestosterone before fights, these days 20mg of chewed Halotestin kicks fast. Especially useful when depleted, just to grind out a workout that feels satisfying.
