here's the deal... deca makes your joints feel fucking amazing... theres NO denying it HOWEVER, its temporary... its a band aid to a wound and mk has true healing... not to mention, clearly there are far more things to worry about with deca in terms of side effects... so you just have to weight if you want a more long term solution or a temporary one that could cause other side effects... look, deca is one of my favorite steroids, period but i have never been a fan of just using it for healing because its not REAL and im not a fan of masking wounds because ultimately, you end up worse off because you push it because it feels great but in reality you are making it worse... you can use mk far more long term because there is little time off required in between as deca as well...
