Stacks of compounds should be specifically designed with your goals in mind and utilized for their intended purposes. Typically as well as my opinion, stacks should be designed with the use of test, a 19nor and finally a DHT or DHT derivative. Which right away you can see it does not include (2) 19nor compounds.
Tren has amazing capabilities in nutrient partitioning to pack on lean muscle, strength and has thermogenic effects that will aide in burning fat and keeping you lean as you grow. Tren also does not aromatise and will not convert to DHT.
Deca (not necessarily NPP) is used to put on mass and therefore will almost always cause a significant amount of water weight, there is very minimal strength gains and the muscle put on is usually very slow and minimal in comparison to Tren especially with the long decanoate ester. Also, Deca does aromatise but at about 20% the rate of Testosterone. Deca will not convert to DHT either.
Now that you’ve got that info, both compounds have the potential and will, to a degree, raise progestin levels in the body. They both can come with some androgenic sides of their own as well. This in particular is why you would not want to stack these 2 compounds. You’re sort of playing with fire and exasperating the potential of the sides from both by stacking them together. Not to mention negating their particular uses.
