best protein

Review by masa on Jun 13, 2022
Fast, lean, tasty, and easy on the stomach. It is expensive but worth it. It’s also easy on the stomach than most WPIs I’ve tried.

Nare bijwerking

Review by Zoë on Aug 16, 2021
Wellicht goed product maar ik ga hier heel slecht op, binnen 5 minuten moet ik op de wc, niet fijn! Dit was voor mij niet een goede investering en jammer dat er geen test verpakkingen verkrijgbaar zijn.
