I understand the rational behind it, but I've experienced no difference in DHEA, Prog, or Cortisol levels on it vs. off of it. I Can't think of seeing anyone else that noticed an improvement there either, but i suppose it's possible. I still use a very small amount of it to preserve some LH stimulation.
I guess there's a couple reasons I don't like it (and this is personally, I'm not saying it's the case across the board). It can be a messy drug if you are taking a AI. All of a sudden you are dealing with 3 different drugs all with 3 different half lives
Also, I don't really seem to benefit from it. If I take a shot of test cyp or test prop I can 'feel' it. I've never really felt anything off a shot of HCG (unless it drove up E2). It's like injecting water, which seems to result in improved #'s on a page. Maybe this is the reason HCG mono doesn't seem to work even when #'s look good? I don't know.
I don't doubt that it can be beneficial in some guys. But, I think you have to weigh benifits to hassle, and if that ratio isn't good then it may not be worth it in some guys.
I would for sure recommend that everybody atleast try HCG to see if there is an improvement though.
