HMB has been around for years and has always been expensive. This is very unfortunate considering how worthless I believe it is.
During the first few years it was available I dabbled with it off and on. Sometimes I would use it months at a time (my god I want to shoot myself for pissing away all of that cash). I was young and I bought into all the hype and marketing. I can honestly say that I've never noticed anything in the form of muscle preservation, recovery, fat loss, or any of the other things that they claim it does.
One year ago I even bought some once again just prior to a shoulder surgery I was having. I was desperate to slow down muscle loss while my shoulder healed. I figured what they fuck, it didn't work while I was training but I'll give it a go after surgery. I lost 18lbs of muscle during my recovery. I really can't imagine losing much more
Summary of the story, HMB is fucking worthless. And I’m an idiot for trying it (multiple times).
