Does epicatechin blunt muscle building effects of lifting?

[Drewjistu1000]

I came across this study earlier today that says that Epicatechin reduces igf-1 probably by turning on AMPK. Both of these functions would be negative for muscle building, correct? Should I stop taking it before my workouts? https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3095141/
