I've been cycling on and off of Jack3d and I'm ready to take it once again but the problems is that Amazon for some weird reason has not stopped selling it. I've been buying it from Amazon for months but now it's gone. I need a supplement that is just as strong as Jack3d and that is also low priced just like it. Any suggestions??? I also hope that Amazon sells it since that were I buy most of my supplements. Thanks in advance!
