My buddy has been running test e for 6 weeks at 600week and tren a for 13 days at 100mg eod. Both are Alpha Pharma so i dont think quality is the issue. All pins are new and alcohol wipes are always used. He does however get large lumps and bruises on hus glutes. He thinks maybe the problem is reinjecting too frequently in the same spot. Hes scared to inject anywhere else cuz pip is usually horrible. The only flu symptoms are fever, lethargy and muscle/joint aches. Any imput on what the caues may be or what he should do for future reference would be appreciated. Thanks.
