Buuut you're not running tren now?
Here's just a small thought- maybe you were running bunk gear from them, and that's why you developed some gyno? I would GUESS your mast, tren and test were all really test, and your letro was bunk, hence the lumps. But, what do I know? Masteron SHOULD mitigate a lot of tren's sides, and low levels of prop shouldn't cause gyno with properly dosed letro, in my opinion. However, it's clear you're set on using these guys, so I say go for it.
As far as the cycle, I see no advantage of using Sust over cyp/enan. Never seen 200 mg primo, but, that would be a solid dose.
