I could not find SINFIT protein bars anywhere and the places I did find them ( online businesses) had phone numbers with customer service reps that would not answer which concerned me a great deal! At supplement warehouse it was very different because someone answered immediately and expedited my order almost instantly! Now I must add that the quality of the product along with the exceptional customer service and experience I had with this company was as is outstanding! The discount I received as well as the confidence and knowledge of the product by the person at the warehouse is phenomenal and as consumers we want the best. There is no doubt in my mind I chose the very best company!

Excellent protein bars

Tons of protein, great taste (probably the best of any bar I’ve had) and very filling. Highly recommended.
