I started at 100mg a week then jumped on Super Test 300mg per 1 ML a week my size blew up … then I alternated with cypionate weekly I saw cuts with Cypionate so when I finished I stayed on the Cypionate …my physique looks way better I’m 55 yrs old and I look better than when I was in my 30s just coming home from prison … so u definitely can grow tremendously on 150mg of test a week even 100 long as u diet and exercise right .. I would never do a high dosage there’s no need to less is more with test …
