Hi mate. I too have never used one as my test to 19nor compounds (tre/decca) has always been about 2:1. Im starting a cycle of a blend containing 50mg test p, 75mg tren a, 75mg mast p per ml. 1ml ed. 8 weeks.
As its the first time my tren is higher than test im going to add in caber @ 0.25mg 2 x per week.
I have only recently become aware of the theory of using tren/decca at a higher dose than test. Upsides to this theory seem great with the only downside being high prolactin.
also running hcg @ 250iu 2 x per week and 0.5 arimidex eod.
