Personally I find this a great wellness stack than a fitness stack.
GO2Max is a supplement I have been using since it was launched. I do find it helps a little with improving my cardio, but it's not a necessary supplement, it's for the people that want that extra 5% improvement one barely notices.
I primarily continue to use it because the studies of the antioxidant benefits of NMN seem promising.
GLP Max is a little bit confusing to me, because I didn't noticed significant change in appetite or cravings. But I could definitely feel the impact on my gut from the probiotics, it's probably par with the most effective probiotics supplements I have ever tried. If this was on sale at a price lower than my favorite probiotics, I would definetily purchase GLP Max instead.
