Please help, reoccurring cycle problem!

Hello I've noticed this a couple of times now on cycle. I'm currently running tren ace eod and test 400 2x a week.
I've noticed that my muscles look smaller and depleted than they did before cycle... this is not normal as im eating a huge amount and I know my gear is reliable. I was wondering
Could this be down to high estorgen? Or any other factors it's real starting to annoy me as I should be feeling at my best but I think I look worse than off cycle! I have arimidex on hand
I can mainly notice the muscle mass lost in forearms and arms

The information you provided is not consistent with the problem you are experiencing.

If your gear is legit, you won't lose any muscle no matter what. I think it's in your head. What does the scales say? Tren is one of the most anabolic compounds available. That in itself will lead to an increase in protein synthesis. Protien is what actually builds the muscles, so if you're eating high calories as you're saying (a lot of proteprotein n as well) and taking tren and test in the doses you're saying, you're not going to lose any muscle even if you stopped working out. It's just not a possibility if the steroids are legit. Protein synthesis proves this to be a fact.
