On 200mg per wk of test my range is between 700-1200ng/dl. The day after my shot I’m around 1200 and by day 6-7 I am down around 700. Anything over 800 is optimal and you can float around 1100-1200 with usually no health issues. But I would make it a point to donate blood on the regular. As for arimadex, I got away without any the first couple yrs of trt but then estrogen started elevating a tad and I began using just 1/2mg 3x a week and it keeps me in good range. As for hcg I usually just hit a whack of it every 10-12 wks for 2500iu x 2 wks, and this is mainly because it comes in 5,000iu vials and to use the standard 250iu twice/wk means the shelf life of 30 days aftet constitution will expire before I use it all. I dont want to waste it and preloading pins and sticking in freezer to prolong shelf like after constitution is a pain.
Tren in either ester can have wicked sides, long ester I have always experienced the sides to a lesser degree, but still there. If your hell bent on Tren at this point, go the short ester route and run it for 6 weeks and see how you feel. My personally opinion, at 3 cycles deep you're better off to run masteron in this stack instead of Tren. Again, you can use a short or long ester version. I seen your pics, you already have a lean build. Masteron would serve you well and compliment the test greatly too, and I've always liked a mast/test/EQ stack as well. My advice, swap tren for masteron at this point.
ofcourse you COULD, you could do what ever you want! The question is would it be worth it and the answer would be no! I would never advise someone to use an oral bulker at the end of any cycle, only a cutter or hardener. The reason for this is because when the body puts on weight it needs time to adjust to that weight, the longer you keep that weight and build muscle on it the better chances you have at keeping it. the only exceptions would be someone who is using it as a preworkout or someone that it using it for added strength such as a powerlifter.
