I find the combination of these two products to go great together, compliments each other perfect! The only aspect of doing Tren E that bothers me is occasional nausea along with my esophagus feeling burning sensation. This sensation lasts for about 5 minutes then fades away. There's no getting around the Tren reaction to the body, its just part of the game. With respect to gains and results , significant increase in strength at the gym. With physical appearance, a very clean dry gain in size, not watery bloated like other steroids. You get a big SOLID APPEARANCE ! I just ordered more Tren E. I'll show my bottles once they arrive . You'll then understand, I wouldnt buy the product and in a large quantity if I wasn't satisfied with Kalpa's Tren E product. I choose the longer ester intentionally because it allows me more time to space out my pinning which is a bit of a pain. : )
