I do believe the halo test is a xtren clone and is fckn Awesome. You should gain 10 to 15 lbswith in the the first two weeks! The compound 20 is a recomp type PH which is actualy a good idea while running a xtren clone. Should help keep the water off that xtren can cause. Also, you will need a clomid for PCT for xtren. It has progetsin sides and nolvadex can and will cause major sides esp gyno. Also dude said something about fishoils, this is a must when running a ph since it really helps with blood platelets. Also Hawthorne berry for your BP since xtren can also raise it. Hope this helps broski. Anymore questions just PM me and ill get you you going in the right direction.
