My friend bought optimum nutrition micronized creatine and the results are just amazing. He is using it from nearly two months and got a good muscle size and strength. All we know that creatine does water retension in muscles and provide fast water supply to muscle to grow them bigger.
The key benefit of this product is that it instantly soliblize in water and hence instantly absorbed by blood as it is micronized. Very impressed by this product.
Also its a cheapest supplement among all. Being micronized i’ll suggest you to buy this then monohydrate.
