Never tried Musclegelz AH, though I've wanted too. Actually my plan was to stack it and Nor Andro for my next run. But with the new turn of events with Alpha Gainz coming out with TD Nor and possibly finally landing TD Androsterone, that may change things a bit. I did try Platinum Nutraceuticals' Andro-300 (TD epiandro) before and it was ok but nothing exceptional. I highly prefer androsterone over epiandro though, epiandro makes me a bit aggressive and angry sometime which isn't an overly good thing. That and androsterone has been found to be slightly more anabolic which is always good.
For my stacks I generally like to run the andros one TD and one oral. I feel this allows for maximum absorption of each without resulting in too much TD to apply. Also, I believe certain derivatives just plain work better through TD application (4-DHEA being the big one here, TD is AWESOME but I get next to nothing by taking it orally). The DHT pros (epiandro and androsterone) both seem to work fine oral. Nor Andro is the one I really want to explore further and see if TD is the same or better than capsule form.
My original plan for future cycle was Musclegelz AH stacked with a healthy dose of IML's Nor Andro. Now though it will more than likely be Alpha Gainz Nor Andro TD and IML's R-Andro. I'm thinking TD Nor at about 300-400 mg stacked with 400 mg of IML's R-Andro to run around late winter/early spring of next year.
Side note, my current cycle is kicking ass too. Strength is going up steadily and vascularity is just insane right now. I'm hoping the high dose of Nor Andro will yield some good mass gains. Still eating very clean and slightly above maintenance for calories.
