The tren and test looks decent - but, I agree. 12 weeks + I liked my long tren and test cycle. But, the lower dose is key since this a long ass cycle. I'd even consider dropping the tren a tad, but 400mg is fair.
I hope you know about your ai's, hcg and prami or caber(I like having letro on hand now when running tren, this is just my preference) After 5 months of being on tren e with a month break in the middle I got some sort of gyno flare up. I know it's not from the test since I was only on 350mg per week.
Also if you want to drop massive Bf% you can run a pretty strong caloric deficit. The tren and test combo will still try to pack on LBM while you are losing fat.
As far as the var, I'd throw it in at the end - when you are the leanest. I'll be doing this on my next cycle.
Also, I can't really say the best for a long estered cycle for a cut. I was doing it & water retention was a bit of a bitch.
