  • 4.6/10  Bad Taste

    By Kristin on Thursday, May 5, 2016 11:23 AM

    Effectiveness: 5/10

    (-)  Tastes Bad

    How did you use it?:Before Exercise

    "I ordered the powder form of L-Arginine rather than the capsule form and I'm regretting that decision. This product has a horrible taste and there was no other option for flavour (I got unflavoured, the only option available). I tried it with just water, then mixing it with juice and then my protein shake but it didn't help. Would recommend the capsule route to avoid disappointment.

    I only took the product three times so cannot comment on it's effectiveness so I gave it a middle grade of 5.

    As to the value, I put 1 because I will be trying to get my money back or throwing it out."

    Would you buy this product again? No
