I have seen people run it both ways, low test high tren or the same dose for both. Especially your first go with tren, i would run test around 300, same with your tren. Thats what I will be doing maybe in 10 months or so. Get some primi or caber to help with the sides from tren if you got them. If you start seeing gyno and your on an Aromatase inhibitor (AI) with the test, than you know its the tren. Or if your little man dont work, or pushin rope as some would put it haha, you would sure want to have something on hand to control the release of progestogens.
