As you have probably seen throughout the forum, everyone's opinions on this differ from person to person in terms of how they like to feel when running gear and the goal you are aiming for. From the very beginning and up until today when I use gear its to try to get as big and as strong as possible as I was a very small guy to begin with. To do that you are always looking to bulk and put on weight, so medium to high Test will always go in your favour there and with that will come water retention generally. So in return its not ideal to run that level of test if you want to cut down or remain pretty lean, & because this is what most guys are wanting to do when running gear they will run low test. Its also because many simply don't like the feeling of heavy test and also get estro sides. As the Tren level increases it generally has you more winded too when training esp if going over 450mg/wk, I find high test combats this feeling because of all the excess energy it gives you. Times when I have had bunk or underdosed Test I have felt absolutely rotten when ran alongside tren. Rule of thumb I always went by was 2:1 Test to Tren ratio. I know plenty of others who run it this way also - but many that won't go over 300 to 400mg/wk too. So its really all down to your personal goals and how you like to feel on gear.

Just thinking back many years now to when I first ever ran Tren ace - I did it 350mg/wk, Dbol 30mg ED and Test 500mg/wk and I also did proper bodybuilding training back then with arms and shoulders etc so would regularly inspect changes in the mirror lol Seriously that was the first ever time I properly felt like I was on a proper steroid cycle, the daily changes in size and definition were incredible to see. I suddenly realised how all these other guys were transforming overnight, I think you will really enjoy it.
