The Ronnie Coleman glutamine XS is an excellent product as it taste as described. No taste at all. When I stop taking it, I do feel more sore. So taking it helps to reduce soreness and recovery.*

Muy buena oferta, se disuelve muy bien en agua ni siquiera se nota que mezclaste algo, no deja grumos ni residuos en el fondo y deja un ligero sabor a agua carbonatada*

Like all glutamines in the market. Yes, of course, they are first class and the amount of consumption is also small, which is very good*
