I have done my first and only cycle. My cycle designed by a pro trainer working with Chelsea. He said me I do not need any pct. Before the cycle I am 170lbs with 12%bf and 11 weeks after the conclusion of the cycle 195lbs with 6.5%bf. I can run much much longer, my strenght coupled and my stamina rises to the sky. I can go even much longer and harder in the bed.My cycle was for 15 weeks. I haven't done my blood check. because i can't go to hospital. Do i need a pct. My cycle is:
