On the back of the package it implicitly acknowledge the superiority of animal products: "possibly the most potent non-animal product known to man"
The common paleo response encourages real food over supplementation. Personally, I find it hard to consistently get the mega-dosages of protein encouraged for helping people mask. Whey protein powder is the best protein supplement. Personally, it doesn't sit well with me. I think I have an immune response to whey. Most powders are isolate so they shouldn't contain much, if any casein or lactose. The immune response I have is likely highly individual to me. Try whey out if you haven't (I imagine you have). If nothing else, it's way cheaper (pardon the pun). My adverse reaction has kept me just eating whole foods which is probably a safer route to begin with.
Eating a large amount of protein isn't great news for longevity. The paleosphere is still low-carb centric. For muscle-building (if that's the goal, I don't know your goals), carbs are very important because they fill glycogen stores. The high levels of protein required for gluconeogenesis move folks dangerously towards protein toxicity. It's problem fine for a season but it's not a sustainable lifestyle.
"Those who are content with maintaining an ordinary person’s muscle mass can get by with relatively low protein intakes of 0.8 g/kg/day or less. But muscle-building athletes need high protein intakes, around 1.9 g/kg/day, to maximize the rate of muscle gain. If they eat low-carb, they may need even more protein. Such high protein intakes are likely to exceed the threshold of toxicity." http://perfecthealthdiet.com/?p=2712
