Proeft wel eerder naar een speculaas mix chocolade, maar nog steeds heerlijk en merk zeker wel veranderingen.

Goede gainer

Review by Michel on Nov 9, 2022
Gebruik deze al een tijdje naast het wielrennen en doet wat het moet doen. Eerste week was even wennen/doorbijten. Smaak is goed, het mengen (met water) werkt voor mij het beste door gewoon de aanbevolen hoeveelheid aan te houden, teveel wordt waterig en te weinig lost slechter op. Al met al, top shake!
