Nandrolone might be hurting vascularity

[M302_Imola]

sure, angiogenisis is growth of new blood vessels
VEGF stimulates this growth

that had some rats, made them exercise and VEGF's effects were inhibited when they were on deca vs when they weren't.

This means the muscle builds fewer new blood vessels and therfore less aerobic ability on deca vs not.

It's important if you're say a running back or something and your aerobic ability is very important.
As far as weight lifting it's still very important.

gotcha...thanks for the breakdown. That makes since.

So deca isn't a really good steroid?

So deca isn't a really good steroid?

I didn't say that...just that if what holds true in mice happens in humans too, it might not be the best choice if you're concerned with endurance.

When you're cutting and doing a lot of cardio it might not be the best choice.

Also for people who are on HRT that includes deca, it could cause a lot of problems.

It's still a potent mass and strength builder, just more info to think about in you cycle choices.
