Clear Protein + Collagen

Unbelievable chocolate taste, I eat it at the office, it curbs my hunger and keeps my blood sugar from spiking.

Jean

Fast delivery and above all the product is top notch, no aftertaste and mixes perfectly. I take it with my shaker or in a small glass of water. I took the 187g but next time I'll take the 317g.

I recommend Collagen Mango Flavor, an inter-cosmic hit. The taste of mango is magnificent for drinking throughout the day.
