I got some what lethargic from DTH/Sunami, but I wasn't in PCT like you. However, I got excellent results from my ride with the stack, and I feel it was just among other things an elevation in gh release, as I slept like a baby on it and recovery was outstanding. Once I hit the gym, it was all good. You are seriously gonna love JP8, it's even way more effective when DTH is in the mix. I can't really compare it to anything out there, as that's not even remotely fair to JP8. I was able to lower my dose of it because of the synergy of it and DTH. Overall, I didn't and still don't view the lethargy as a bad thing, given the results I achieved. I just countered it with a quick nap here and there. Good luck!!
