If its Tprop, some peeps is real sensative to it. I can stand it, but it hurtz. Its not a great choice for a cycle. Better to start a cycle w/ it and Enan or Cyp, or tapper off on it to end a cycle. ITs fast acting.
Couple days and gone.
Taking a couple shots and stoping could set up a rebound hormal reaction, I'd have Nolva on hand.
I dont think you'll need it, but if I started to itch, hurt, or swell, I'd take 20mgs a day, down to 10mgs,
over 2-3weeks.
If you could lay your hands on some Enanthate or cyp, I'd switch to that, save the rest of prop to come off on.
Again you need find out what your using.
