I bought the 2pound optimum whey gold standard [extreme milk choclate flavour] for Rs4700 this ramazan from GNC.
I went for the 2pounder as this was a new flavour for me which I hadent tried earlier. Otherwise I buy the 5pounder which is 30% more economical per scoop
Optimum and dymatize are 2 brands in pak which dont do amino spiking with useless filler protiens
I am also using these 2 brands-- this pic is not mine however.
With the dymatize gormet elite chocolate however i add milo or coffee pwder in the shake along with milk
These brands are GMP certified
