Welcome back, MicroSlash! It's always nice to see familiar names come back. Glad things are on the up and up for you, as well.
Indigo-3G would definitely help. It's pretty impressive in terms of improving body composition and carb tolerance. If you use it, just make sure you do eat plenty of carbs, especially peri-workout, as this will yield the best results. Gotta eat 'em for it to use 'em.
Outside of that, you know workout nutrition is where it all starts. Have you tried Plazma yet? Plazma before and during your workout with Mag-10 post is awesome. I also like to pulse with Mag-10 throughout the day. (I found pulse feasting to be super simple while providing real results.)
With your diet dialed in, that would be an excellent jumping off point. You can always add in Hot-Rox to kick start fat loss again.
Again, welcome back! Oh, and there are also dedicated Biotest forums now too.
