Been buying Ultra Peptide and Ultra Peptide Whey since about 2013 so maybe not as long but certainly as many and that is not the experience I have had with it.
I have on hand Metabolic Nutritions Musclean which I love as well and will post a pic to compare
Musclean Here Chocolate Milkshake blended quickly and poured into the glass clearly has a little foam did not detract for me at least how good this is I love their strawberry milkshake most FYI, even more than the Ultra Peptide Strawberry
but all of their flavors are very good. So this is not a knock on Musclean/Metabolic Nutrition but this is a similar type of product utilizing similar blend with shelf stable sodium caseinate sunflower oil, so I felt it was worth comparing foam wise.
And Ultra Peptide same milk's used on all of them Fairlife
Almost no foam at all/very little; this was done in a blender poured into the glass picture taken immediately
Shaken in a blender bottle here very little to no foam
Strawberry here in chocolate milk shaken in the blender bottle, picture taken immediately.
Triple Chocolate Ultra Peptide blended in a blender immediately poured into this glass and picture taken directly after.
Not saying it "Never" has any "Foam" under any condition/circumstance but I literally have taken a lot pictures of protein it does not foam any more than any other premium protein blend that I have noticed or experienced; including Metabolic Nutrition Musclean ( which foams slightly more if shaken and the same blended ), PES Select, Syntha-6, Rule1 and about 15 other brands like AI Sports on hand even.
So that has not been my experience with the Ultra Peptide
Ultra Peptide Whey however; I have had that foam up but no more than any other straight whey tho when I blend it with ice which is how I typically use "Arctic Lemonade" I believe the ice sits heavy enough to keep the foam down. I would have to sift through lot of pics but the Arctic Lemonade if shaken in a shaker has some or rather much more foam than the blends.
