I recommend this product

Good Product. Good Price

I have purchased the larger quantity of this product over several years. The price for the product in the 1kg and 5kg is good with the 5% or 10% discount code. BulkSupplements does not give discounts on quantity sizes greater than 5kg so purchasing sizes greater than 5kg is not recommended. The product easily dissolves in milk or water and does not have objetional taste (fairly tasteless) so it is easy to consume in a pre/post workout shake. I believe it is best combined with BCAA, other amino acids, and Protein powder for most effectiveness.
