Nighttime recovery is crucial for daytime performance and success. PROGENEX Cocoon, the best casein protein powder, combines just what your body needs for a deep, restorative and reparative sleep so that you wake up feeling refreshed, rejuvenated and recovered. Ready to tackle stress, rise above the daily grind, and attack your most grueling workouts.

PROGENEX Cocoon is a special nighttime formula featuring micellar casein and Metamorphagen™. As a slow digesting protein, micellar casein stimulates protein synthesis through a sustained release of amino acids throughout the night, promoting muscle building while preventing muscle wasting. This slow, steady drip of amino acids is not only critical for protein synthesis, but is also crucial for immune system support.

Train Hard. Sleep Well. Recover Strong.

PROGENEX Cocoon not only stimulates protein synthesis, it also contains the perfect amounts of Metamorphagen™—the powerful tryptophan peptide that reduces sleep interruptions while fostering deep, sound, restorative sleep so that you wake up feeling strong, rested, and fully recovered.

The precise amount of Metamorphagen™ is specially formulated to do all this without increasing drowsiness. Enabling you to maintain peak performance levels throughout the day before wrapping you in a warm cocoon of recovery come night.


The ingredients in PROGENEX Cocoon have been shown in studies to:

Stimulate protein synthesis (Tipton, 2004)
Increase lean muscle mass and strength (Demling, 2000), (Willoughby, 2007)
Prevent muscle wasting (Boirie Y, 1997)
Speed recovery (Cermak, 2012)
Improve immunity (Gregory, 2008)
Enhance satiety (Abou-Samra, 2011)
Reduce blood pressure (Cadee, 2007)
Improve Sleep (Hartman, 1982),
Boost Mood (Thomson, 1982), (Levitan, 2000)

    Very good sleep regulator, with protein. Taste is pretty good, all things considered. I found it damnably hard to keep mixed, the powder constantly settling to the bottom in a sludge. Once I put it in a spill-proof thermos I was able to keep it mixed by shaking it regularly between sips. Don’t use a blender bottle, which aren’t for hot beverages. Get a good coffee shaker than absolutely will not leak when shaken. Use the metal blender thingy from your blender bottle.

    Some increase in bruxism.

    Progenex Cocoon is an incredibly effective product. I have always been the type of person who tosses and turns for 30-45 minutes before being able to sleep, Progenex Cocoon has thrown that out the window. Within 10-15 minutes you start to feel a sensation in your body and quickly fall asleep. It’s a very restorative sleep too. There are night when I barely get six hours of sleep and I wake up feeling like I got eight. Any soreness from the previous day’s WOD is gone, you wake up feeling as if you took a recovery day and you can take on that day’s challenges with fresh muscles. Progenex Cocoon is a little sweeter than some of their other products, so water is not the best blending agent. Vanilla almond milk, soy milk or coconut milk make a better mixer. This is a drink that is intended hot. For best usage I do recommend first heating up whatever liquid you’re using and then pouring it into a coffee thermos not a blender bottle. Throw in the blender ball, shake and enjoy. Progenex Cocoon when combined with their other products can allow you to make tremendous gains in your fitness goals.

    I am a nurse and a crossfitter and i love this product. Working night shift, being a mother of two young kids and training hard means my sleep is important but when i can sleep changes from day to day. I honestly wake up less sore and more refreshed. after my night shifts i am able to stay asleep longer and fall asleep faster. i never feel groggy when i wake up and i honestly went from drinking a pot of coffee a day to drinking only 2 cups.

    Cocoon is an awesome product! As a firefighter/paramedic I work 24hrs on 48hrs off, which can really mess with your sleep schedule. Cocoon helps me reset that schedule on my days off by helping me fall asleep within about 30min of taking it. If you have troubel sleeping you wont after taking this.

    This is the best recovery drink EVER. I sleep like a baby, and the cinnamon flavored Cocoon is the best. It tastes just like warm horchata, which is surprisingly delicious. I drank a cup just now… good night soreness. zzzZ

    Cinnamon slumber tastes good but tastes like there is 100g of sugar instead of 6g. I sleep great but the last 5 sips are hard to finish because it is so sweet,

    Doesn’t disappoint! Cinnamon Slumber tastes awesome. Highly recommend it for anybody who takes their recovery seriously.

    I never wake up hungry or too light. Tastes much better than any other casein. Drink it hot for sure. My wife and I use the Starbucks milk frother and it mixes perfectly. Our bedtime ritual!

    This stuff ROCKS! I tried the Cinnamon Slumber and I slept the best that I have in months. I actually woke up to my alarm rather than several hours before. I used a Hydra Flask to mix Cocoon with hot water and didn’t notice any clumping whatsoever. The taste was great.

    I’ve only use it twice so far, but have slept very soundly both nights. First night, I used hot water, and had some mixing issues, second night, I used warm water in my mixer bottle and it was perfect.

    I love the idea of a recovery nightcap, especially now that it’s cool out! I’m a good sleeper anyway, so I can’t speak to that aspect of cocoon.
    Both flavors are meant to be mixed up hot. DO NOT mix with a little cold milk & then with hot water because you’ve just lost the battle right there. I had zero trouble blending when I put the cocoon in a blender bottle with the ball, then poured in heated water from the kettle. Lid it and shake just a couple times and then quick pour out into your mug. If you take too long to shake the bottle will explode 🙂
    Flavor? Chocolate was good. Cinnamon is super crazy ass hella sweet. I think it’d taste good either less sweet or watered down by about 24 oz. It’s like sweet cream with real cinnamon, not the red hot flavor. Another reviewer said horchata, that’s pretty close! But the sweetness is really shocking, so be ready for that 🙂

    Love Cocoon!! Silk Chocolate is pretty yummy but Cinnamon Slumber is delicious – tastes like a cinnamon roll!! Within an hour of taking it I have no choice but to sleep, and sleep hard!! Thanks for the awesome product, Progenex!

    I’m not normally proactive enough to write a review, but I’m obsessed with this product! As a grad student and crossfitter, my schedule is crazy and often I am up on my computer right until bedtime, which is known to disrupt sleep. I’ve taken Cocoon for a week now, and it has dramatically improved my sleep. I get tired within 20-30 minutes of drinking it, and fall asleep quickly. I have woken up with less muscle fatigue and never groggy. I bought the large bag of the silk chocolate and a single-serving of the cinnamon slumber, which was a great decision. The cinnamon slumber tastes like horchata (VERY SWEET), which I would drink occasionally but wouldn’t be able to handle every night. The silk chocolate tastes like Swiss Miss hot chocolate mix, which I prefer. Either way, it’s a great product! Also, I am lactose intolerant but haven’t had digestive problems…another plus!

    LOVE IT!!!!
    I tried this for the first time last night. I can’t say enough about it. I slept so soundly, which is a constant struggle for me. In addition, I’m not feeling any muscles soreness or fatigue today and I woke up feeling refreshed. My new favorite product. Can’t wait to order more.

    I liked the chocolate taste. Its kind of like a hot chocolate before bed. I do recommend you place it in a shaker bottle to mix well. I only took half the packet though in case it was too sweet. It was perfect. It did knock me out though so it does have a mild sleep aide. However, if you have difficulty sleeping this would be great.

    Really enjoying this product. The chocolate tastes good, and it does help me have a restful nights sleep. I am someone who suffers from fitful broken sleep, and I am experiencing a noticable difference since I began using Cocoon. No BS!
