Pretty much agree with
IconicForm on everything. DCP does not target cortisol. Evomuse Ammo targets cortisol, and it is VERY strong. Honestly, I think it is incredibly under rated for this. I've repeated my experience on here a few times, but here it is again.
I've run 11-Keto extensively and this compound is touted as being a powerful cortisol suppressor. I've run 11-Keto at up to 1 gram per day transdermally. At one point I was taking 450 mg about 30-60 minutes before bed and the enhanced sleep was very noticeable. This was one of the "big" acute effects I've noticed when I reduce cortisol and 450 mg is about 5.5X the dose that some products use daily - I was taking in 1 dose.
I've taken Ammo as recommended, but at 2 caps pre-bed (2x the recommended dose of Ammo) the sleep was extremely similar to 450 mg of 11-KT. Now, there are hormonal effects of 11-KT beyond just cortisol, etc. and I'm not making a direct comparison that 2X the dose of Ammo = 5+X the dose of 11-KT, no way. I can't even say the cortisol effects are directly similar - I don't have blood work - but the experience was similar and I doubt any other product on the market can make that claim.
If you use 11-KT, as IconicForm points out - you really should have a PCT ready to go, even if you don't think you need it.
I am a big fan of 7-Keto DHEA also - it can be run solo without much worry and is effective and I would also recommend it as part of a PCT for 11-KT although it's not necessary.
