Glad to help bro! And glad you like the log, thanks a lot man. I feel like sometimes I write too much minutiae no one cares about lol, but hopefully there's some informative bits in there too.
Unfortunately I didn't make it to pro, got close but placed 2nd by a few points. This year, I'm out for blood!
As someone who's been fat for far more of my life than not, I feel you man! My thoughts are you should go with Micro. Just my opinion based on using these supplements for years, Indigo is really good for a bulking phase where you want to pack in the carbs. If you're focusing on fat loss, Indigo would still be helpful for nutrient repartitioning, but I think you'd get more out of it in a well thought out caloric surplus. Hot Rox is a great fat burner, but I think you'd get more long term benefits from Micro-PA. Even though you're not in a "bulking" phase right now, Micro-PA will still work well and help you get some more LBM. And, with more LBM comes a faster metabolism, more strength, easier to maintain leanness and put on size when you're ready, etc. So even though Hot Rox might give you a slight advantage to fat loss right now, Micro-PA will help pack on more LBM for more permanent and long term success.
I do not take PA on non-training days, better for my wallet over time. But I take it every training day, either 5 or 6 days a week depending on my split. Another note is that while Indigo and Micro are the same price, there are 20 servings of Micro in each bottle. So if you train 5 days, that's a month per bottle. If you can swing it, I'd recommend 3 bottles, definitely at least 2, so you can take it long enough to see substantial results, also ensuring you're training in a way to take advantage of the PA. When I started taking PA, it was a few years ago when I really got more into bodybuilding style training and developing a strong MMC.
The 5/2 diet is a good way to fuel your work out sessions and provide good growth and repair, while using the 2 off days to keep insulin sensitivity and excess body fat in check. If you really want to get lean, like defined 6 pack lean, I'd recommend eventually doing a contest style diet and training routine. Not that you have to step on stage or go as all out intense with it as a competitor would, but once you get down there the first time, it is infinitely easier to stay there and put on quality muscle without going overboard. Leanness is ultimately made in the kitchen and with cardio. I highly recommend doing this at some point. As a FFB, life is totally different and awesome when you're confident in how you feel, look and know you are in total control of your physique.
Be sure to post with any additional questions man!
