So heres my situation. I started 6 weeks ago on a cycle of test e @400mg's a week. my biggest motivation for starting this cycle was because I had a test level check and it came back low. Long story short my doc put me on 200 mg's a month. Needless to say that was making it way worse. He wouldnt up my dose so I decided to run my own test. Anyways I have been on the 400 mgs a week and I have had great gains, a nice sex drive boost, awesome size and strength gains, feel much better. However this past week I started a different brand of test(cidoteston amps 250mg/ml) 2 at a time so i bumped it up 100mg's. And this past week I have been feeling more lathargic, less sex drive. just overall not feeling as good. Did I get bad gear? Maybe the bump in mg's is causing it? Anyone out there had this same experience that can help me out?
