Tren is an awesome compound...
With that said, dont complicate it. Keep Caber/Adex on hand.
I have run TestP/Tren A/Winny. When i was on the winny, i didnt have much of an issue with prolactic/estrogen side effects. As soon as i came off i started noticing my nipples getting sore/pointy. At that time i started caber/adex, and the sides went away. I also keep letro, in case of an emergency.
If you are trying to lose weight follow a T-3 protocol, and do not eat like an animal. If you arent getting the muscular results you want, eat more. Only you will know how much to eat on this cycle. There is nothing we can really tell you.
Since you have ran Deca, you will notice the same sides with tren. Since you are looking for fat loss, 75mg tren/100mg/prop ED would be ideal, however, that will ultimately depend on your diet and training (I know, its cliche, but true).
Watch your Blood Pressure and prepare to be a pin cushion.
