I previously ran a test p cycle and everything was fine. I made gains, pip was gone after first few shots and no fevers. Now I run test e from 2 different labs one being northern pharma so I know its legit because they're a legit company from what I know and both of them got me a big fever the day after with extreme pip. My injecting technique has been the same as with the test p. And to top it all off it has been 4 weeks and there has been 0 gains. Im thinking its something to do with the big fevers I get. Once I get some more money I will buy more test p but can anyone explain this?
