I'll try to keep this short while still being detail oriented.
The Good:
I had great results with the xgel(1.5g)/ABE stack. My ultimate goal was to gain strength. I put 40lbs on my bench. Went from 4x205 to 4x245. Wide grip pull-ups went from 10 to 14. Grip strength improved. Deadlift went from 12x225 to 12x255. Just to give you an idea I'm 5'8" and overall I gained 14lbs and 4% BF in 3 months. Started 158lbs finished 172. I'd say roughly 2lbs of that was water weight because over the last 2 weeks my weight has readjusted and I'm down to 170lbs.
I believe what contributed to these results was starting at a low body fat. At the end of April I started a cut for a buddies wedding. By the end of May I dropped to 155lbs at 11% BF from 160lbs. Just used caffeine, yohimbine HCL (.2mg/kg), fasted training, and IF. Life happened June and July gained 3lbs and ~2%BF.
Daily sups
6g Beta-alinine, 5g creatine, 5g taurine, 4g ALCAR, 15g-20g BCAAs, 200mg caffeine pwo. (And another 200-400 the rest of the day.), Multi, Vit c, 2000UI Vit D, ZMA
These have all been my base sups for about 10mos. A lot of these are split dosed. I also used omega3's, but stopped once I started my ABE/x-gel stack. Also added in 4Tbs soy lecithin for emulsifying purposes of the xgel.
I highly recommend you start by reading "The arachidonic acid help guide" if it's something your considering doing.
The bad:
ArA is an omega 6 systemic inflammatory. That means it can cause the inflammation of more then just your muscles. It can do it to your arteries as well. I'd have to find it again but there's a study that directly states this.
My BP was fine before the stack. Around 112/65. The week I stopped ArA and SL it was 147/75. 2 weeks later I'm still in the 135/69 range. I've been using Epic UL TD for the past week and eating beets with my breakfast daily. Added my omega 3's back in. Also taking 5g of ginger daily which is an anti inflammatory.
For the last month of the stack I could barely eat maintenance with out feeling uncomfortably full. Now, 2 weeks later, I'm still eating maintenance, a lot of them the same meals, and I'm always hungry. Even wake up with hunger pains in the morning some days.
The last month I was also short of breath during my runs and couldn't figure out why.
This is just my opinion, but I believe that ArA and SL may have messed with my lipids and/or arteries. I'll be getting blood work done next week for lipid profiles. Had a hormone panel done the last week I was taking the stack and everything came back normal.
Conclusion:
I liked the strength gains. If I can identify what caused the adverse side effects I would run it again. That may require me to run the xgels with GMS instead of SL (soy lecithin). But that won't happen for another 4-6 months.
