Does it compromise aerobic capacity like Tren? How are the back pumps?
Keep in mind, I was pinning Dien-e so I can't tell you anything about pred nutritions TD versions or anything. I only ran it 4 weeks and had to stop my cycle short. Life just got in the way a bit and felt like I was wasting gear so I just decided to call it and stop. I never noticed a drop in aerobic capacity, but I was also taking Cardarine which helps massively. On tren, the difference with and without Cardarine is night and day. I'll never run tren without it again.
No back pumps at all. Only thing that ever gave me back pumps personally was either Trest or Mithras. However, everyone is a bit different because I never got back pumps from Msten, but I know some dudes who said they did.
Dien should give nice leaning effects like tren without some of the bad sides like inability to sleep
