This is a great question that, unfortunately, cannot be answered in just a couple hundred words. There are important issues that focus on educating one's self prior to embarking on such a course of action, particularly the downsides of using steroids – the side effects, the proliferation of fake gear, getting off of them, getting blood work done, etc. And, the fact that buying, selling and transporting them is (in America) still a felony, not to mention banned by all sports federations. All very important salient issues that require a lot of space to do justice.
The packaging of the sis vials is definitely one of the best I've seen, only second to the likes of alpha pharma. Thankfully the contents didn't disappoint either, I swapped from another brand of tren e which I was very happy with mid cycle and used at the same 500mg/wk dose, the oil is nice and smooth with no pip and I continued to get all the benefits and side effects I have come to expect of a good tren e........for me, namely acid reflux on the sides (the caber I got from MR keeps the rest of the tren sides at bay) and strength, aggression in the gym, muscle hardness, veins like a road map.
