Getting ready to start SL Primo 300 a week for 10 weeks and Test Enan at 500 a week for 10 weeks also. My question is my buddy just finished a Primo cycle and has 10 100 mg Schering amps left over should I add them to my SL Primo and make it 400 a week?I know the chemical make should be the same but I have never mixed two different brands together at once what would you all do?
