Tren E Vs Tren a

E is going to have smoother blood levels and less "bang". You are probably trying to match MG and thus getting less total mg at a slower rate (blood levels rise slower) so you arent getting the sides either. Just remember that long esters can compound (add up) based on dosing schedule and if you have complications with E sides then you have a minimal week before they subside, where as with A you can stop and they subside pretty quickly. I believe you are a middle/light heavy right, with very good genetics. I dont see why you wouldnt get away with 100mg eod along with the rest of your stack and look phenomenal. Id stick with the A.  

Night sweats can be combatted by elevating carb intake a bit of having just a bit before bed. People tend to not like night sweats, but to me any sign im thermogenic is a good thing! Its a sign im burning fat in my sleep! The cough lasts maybe 60 seconds suck it up lol.

The Tren Cough is self induced. When pinning, you will trigger Tren Cough if you hit a vein. It's always a habit to pull back on the plunger once you're in the muscle. If there's blood in the syringe, you're in a vein.
