I wouldn't stack RXT with JW as they both contain an AI.
Powerfull, a low dose AI (ATD like SNS Inhibit E, RXT or a 6Bromo like Rebound Reloaded) and a nettle root extract such as Activate by DS is a great one two punch. Cissus is a great addition to anything and I consider it a staple.
JW is nice in that it has the nettle extract AND an AI which helps justify the price.
