My actual muscle gain from EQ and deca is similar. Deca tends to make me hold more water and usually makes me feel a little lethargic, but as for end results, after the cycle is over, I don't see a ton of difference between EQ and deca. Because of deca related side effects, I prefer EQ. Plus EQ seems to be easier to recover from. If you opt for the deca, be sure to use that HCG you're proposed. Anything you can do to help with recovery is well worth it, especially with deca!
