how long after letro to cycle? help

[El Gallo Negro]

Ive been holding off on a test e tren e cycle for awhile due to gyno (lumps and sensitivity). Should i start and run letro in the beginning of the cycle and get into nolva everyday or will that be a problem due to the tren. OR should i just run letro and finish off with nolva to avoid estrogen rebound then wait? if so how long should i wait? been doing the research but really want to hear from you guys. thanks fellas

Why is Tren and Letro a problem as the poster tells?
I happen to have just started Letro, and am takin tren, so curious

letro isnt the problem, from what i ve read its solid product but there is countless threads going back and forth if nolva is bad while on tren and can actually work against you in fighting gyno. are they just talking about pct or does that include on cycle
