The Complete Sustained-Release 8-Hour Protein Formula

Phase8 is designed to do one thing - feed your muscles the highest quality blend of protein available. Each serving of Phase8 delivers a 26-gram blend of proteins taken from multiple sources with variable digestion rates. The multiple release rates of amino acids feeds your muscles for 8 hours - that's prolonged delivery of key musclebuilding blocks, making Phase8 the perfect protein for any time of the day - or night.

8-Hour Sustained-Release Protein Absorption

The main protein component in Phase8 has the unique ability to release amino acids in your bloodstream for 8 hours after taking it.¹ Because of these sustained-release properties it's a highly anabolic and anti-catabolic protein that helps create a musclebuilding environment for longer periods of time.

6 High-Quality Protein Sources

Overall, Phase8 contains protein sources designed to digest at different rates - putting your body in the perfect state for repair and recovery.

Calcium Caseinate 77

Other multi-phase protein formulas contain protein derived from plant sources, such as brown rice or even soy, and are often loaded with fat and carbs. Phase8 contains high quality milk-derived protein and has half the fat and carbs of the leading competitor.

Phase8 Multi-Phase Protein Delivery Digestion Rates

Protein Blend in Phase8 - Super Fast - Fast - Medium - Slow - Super Slow—8 Hrs!

Best-in-Class Taste

Phase8 was flavored by one of the world's top flavoring houses by protein flavoring experts in order to taste better than any other protein on the market.

Take Anytime: Morning, Pre-and Post-Workout and at Night

Phase8 contains a unique blend of proteins that allows you to take it whenever you need it. The multi-phase protein delivery supplies the needed quick release of amino acids for post-workout amino acid delivery, the medium release protein phase for between meals and the slow-digesting protein phase for night time use - making Phase8 the perfect choice for any situation.

Good product

The Taste Is ok, not good and not bad. What matters is the slow digesting process that helps build and save muscles. It mixes not very well with spoon maybe it will be better with a blender.

First impressions were pretty good. It mixes well and, although it has more of a chemical, artificial taste than the ON stuff I usually use, that's not the sort of thing I'd mark it down for - it was after all, significantly cheaper than ON's version. Before I explain the problem then, I should be clear that I haven't made ANY significant changes to my lifestyle since I switched to this from ON. My diet and training regime have remained the same, as have my meal timings etc. So herein lies the rub ladies and gents: This product will turn you into a walking dirty bomb. 30-40 minutes after taking it there is a tremor deep in my bowels; I try to hold on but I just can't take it anymore, and the noxious gases flow forth from my darkest orifice like glycerine clouds from a vaping hipster. Whether it is effective as a meal replacement remains to be seen - it's been relegated to the back of my cupboard as a 'backup protein.' But for those working out to make themselves more attractive, please bear this in mind: if someone you're interested smells this coming out of your other end, you're never getting any. Not ever. Really, ever.
