Hey ive been on test/deca now for a few weeks and overall i just dont feel that great.I def know the stuffs legit but i really cant feel the strentgh gains i usually do just running test alone.This is my first deca cycle and so far im up 12lbs.But im have a lot of tightness in my chest and alot of trouble breathing.I went on a bikeride yesterday and had trouble keeping up with friends i normally could blow away.Im just wondering if this is do to weight increase im not used to carrying on me or if i should be looking into something more serious.Thanks
