This should be stickied!
Ok, let's clear some of this up:
Advanced will work at high and low BF levels, but is going to mostly target VAT and help control cortisol. It can be used at any bodyfat, but from a cost-benefit standpoint it's probably best for those with VAT problems or those looking to control cortisol. It should only be used around the core area.
series will work at high and low BF levels, but is mostly going to target SAT and reduce "stubborn" fat problem. From a cost-benefit standpoint it's probably best for those at lower BF levels (sub 12%). That isn't to say it won't do ANYTHING if you're higher, probably more that it's not really designed to do something at high BF's that will leave you really pleased. CAN be used on the chest, even as a pre-workout on targeted muscles, and even on the legs (be very careful where you get it on you at though).
The products CAN be combined. The best way to do that is to use after showering (preferably with exfoliating soap like Java Lather, but this is not a necessity for use).
2. Dry off.
3. Apply .
4. Allow to "dry" (I usually brush my teeth now)
5. Apply series (Smolder or OG).
Matt has said AA over Eviscerate works way better than the other way around. Something about the carrier.
I've used them solo or together. Together is the most effective way, but isn't something that everyone wants to do and that is quite understandable.
AA can be quite effective though even on lower bodyfats. One good example of that is Mr. Cooper. He really enjoyed it and he wasn't at a high BF%.
