sustanon is the best begginer drug. i used it alone my first cycle ever. i used 250 mg for the first 2 weeks and upped it to 500 for 3 weeks and went back down to 250 mg.. till i finished my cycle. you should try that prymid cycle. as for now... stick with only one a/s save the primo for summer maybe?? only 100 mg of primo wont do shit for you. so save it till summer or maybe colllect more primo amps and do 300/400 mgs in the summer u will love it
