i havent read a lot of great in depth conversations about berberine but i obviously just need to dig more. appreciate your 2 cents.I'd personally just go with a combo of Na-R-ALA + Agmatine + Berberine. Add in Gymnema Sylvestra during a cutting phase.
Need to be smart with dosing Berberine when muscle hypertrophy is the goal though, too much and dosed at wrong times can have negative impacts on lean tissue accrual.
With the above, you'll get the GDA and nutrient partitioning effects, among other health benefits.
