I would be very care with that. 19 Nors are very suppressive to the HPTA, not to mention the risk of proges related issues will go up. If you do, I would keep the deca very low, like 200mg and I wouldn't go crazy with the tren either. I'd probably use tren ace, in case there is a problem. If so, you can cut it out quickly. Start the tren at a low dose and see how it effects you before moving up. I'd also add caber at .5mg 2x wk.
