I go for lower Test dosage and higher anabolics.
My reasoning? My first experience with Tren I was an absolute fucking wreck. By week 4 the insomnia was destroying me. I couldn't sleep no matter how tired I was and I was a walking zombie. Dark circles, lack of motivation, was going to the gym to basically go through the motions and I told myself I'll never touch this shit again. Then I came across a write up on the whole high Tren and low Test cycling style and I said oh what the hell, I have some left over Tren; let's try this again. I ran it and my insomnia that occurred the first time around completely disappeared which was enough for me to be sold on this idea.
I guess the other reason is I'm extremely sensitive to aromatization. The highest I've gone with Test is now, currently on cycle Test E 250mg with 350mg of Tren Ace and even on 250mg of Test E I'm having a gyno flare up that I posted about recently. I had to break into my emergency stash of Letrozole which absolutely nukes estrogen. Relying on this for now until another AI comes in soon.
End note, anyone ever has issue with Trensomnia, give the low Test high Tren a try. It sure helped me.
