Test Prop is a short ester Testosterone. In Laymans terms that means that its hits you quicker and leaves your body quicker. Test P is usually dosed in 100mg/mL and is usually injected ed or eod depending on a number of things and preferences but in the norm 100mg/eod. I would suggest that you dont start anything just yet even though your prob itching too. I have made the mistake with ignoring bros on here and I got disappointed with my results( Basically too much too soon for too long) Now I got some nasty scars on my shoulders from the cystic acne I had. Be patient and ask many questions! Good Luck!
