Agree with Leela.
For the record on HPW diet, was created by Peggy Brewer using Wombaroo brand high protein supplement (WHPS), bee pollen, eggs, honey, and water, following her recipe in amounts, prep, serving, and storage of batch.
Summery:
EN manufactured, or sold a product using another brand of high protein supplement and used the HPW name due to popularity. Made, to my knowledge a "kit" form that included HPS & bee pollen, as well as an instant variety. Again, not the Wombaroo brand, I'm not sure of the name of the brand now first hand, but I was at first believing it was the same as HPW and used the "kit" initially).
Peggy Brewer also created & manufactured a high protein supplement and used it in new diets, she also formulated, called HPW Plus, which is following the then referred to OHPW recipe using her brand of HPS; as well as HPW Complete, which is an instant powder.
There was much confusion, so Peggy trademarked her company/brand name Critter Love. So now OHPW is now Critter Love Original or as I like to call it CLO. The other HPW diets, Plus, Complete, and I believe there are other varieties are also named "Critter Love" replacing the "HPW" part, so as I love acronyms they would now be CLP & CLC.
My Personal Thoughts:
Not sure in what order the other brands of HPS were created, nor how many that are not Wombaroo, but they're out there and I believe, based on much reading up on the matter that either CL or Wombaroo brand HPS is of best quality, due to the fact that I know extensive testing/and use of these products was conducted. The other brand I don't know much about, but I have used them prior, at first due to lack of knowledge, then once again for temporary use due to severe lack of funds. I personally feel the EN brand is lesser in quality, but for short-term use is better than some other cheaper diets out there.
