Hey bro, I have checked it out with AR Nutrition. Here is what they said:

"Due to its molecular form, Peptide tends to clump. We suggest to take the peptide with a protein beverage so that the peptide will bind with the other amino acids. As for mixing, it depends on the protein your using. Some proteins are more soluable than others and that will depend if you need a blender. Try our Xtreme Protein. It is a Whey isolate blend - high quality, great taste and instantized, so it mixes with a spoon. Also, the peptide does not compete with the other amino acids - so you get the most out of the product."

Hope this has helped,
