Tren is weird for sure. But Im curious what your test lvl was at prior to dropping it the 250mg/week. Chances are the sides went away bc SOME not all people respond better to tren when test is low. When I run tren, i have to have my ratio of tren to test at least 1:1 or pref high test, low tren (usually I do 750 test and 4-500 tren, and low mast). My buddy on the other hand gets unbearable sides unless he run his tren 2:1 to test. or even closer to 3:1. Hes currently doing his summer cut cycle at 300mg test, 750mg tren, 800mg mast
I was going for a 12 week cycle of bulk into recomp/cut, so the plan was to do:
4 weeks test:tren 350:350
4 weeks test:tren 250:500
4 weeks test:tren 800:200 (mast prop at 400mg)
In the end I did the first 4 weeks but really struggled with sides and motivation. It was awful, I barely went in the gym and when I did I was lethargic and useless. Even considered a PWO (which I never take because I am ridiculously stims sensitive).
In week 5 I upped it to 600mg tren 250 test and felt better after a week. From week 7 I've been doing 125mg test, 200mg mast, 500mg tren every 3 days and feel like a god. So ratios are at 1:4 on test to tren and 1:2.5 on mast to tren. Love it, and other than sweating and occasional shortness of breath, I'm "side less". Even gyno is easier to control like this.
