    I went through a phase of purchasing their products after working out.

  7. Alex Davis says:

    I’ve been drinking Muscle Milk for over a year now in conjunction with my daily workouts, and this infuriates me.

    ADMIN – Hi Alex,

    Note, the settlement covers purchases pre-2013. I think the product was reformulated in 2012 to get rid of the nasty trans-fats.

  8. Chad Devoley says:

    I purchased hundreds of dollars worth of Muscle and Monster milk since 2007 and it is an injustice to hear that I have been mislead.

  9. Arman Arutyunyan says:

    I would like to file a claim for the full ammount as I have spent well more than $60 on this product

  10. Andrew Nguyen says:

    Since I have left high school in 2007, I have bought muscle milk at least once a month after I workout if I did not bring a protein drink.

  11. Sean Mulligan says:

    Bought a number of the ready-to-drink bottles after workouts between the end of 2011 and all of 2012. Most of the time, I’d buy them at Giunta’s Meat Farms in Farmingdale, NY after going to Retro Fitness next door.

  12. Nick Babyak says:

    Drank between one and two dozen bottles of Muscle Milk over the relevant timeframe. Thanks

  13. Oscar Tsang says:

  14. tbryant says:

    I have bought a lot of this stuff, sad to hear they have been lying about the product.

    ADMIN – Hi Tbryant,

    Note, that it seems like they reformulated the product as part of the settlement. If you look on the ingredients it no longer has the hydrogenated fats.

  15. Alex says:

    I purchased 3 of these ready-made drinks weekly over a six month period in 2010 when i first started weight training but was located in Australia, able to claim or not?

    ADMIN – Hi Alex,

    The class actions are usually open to purchases made in the US.

  16. Warren Clayton says:

    Between 2011 and 2012 these were my go-to post workout drink after track practice before I was introduced to powdered protein for my post workout drink. I would purchase them 3 times a week during this period and would like to be refunded up to $60 for my purchases during this time-frame.

    I have continued to support Muscle milk after the reformulation and am currently pleased with the current claims the company makes towards its formula.

  17. Martin Zanicky says:

    I purchased many muscle milk shakes during the time frame. I would like to be refunded.

  19. Paulina Gama says:

    I’ve been purchasing the ready-to-drink Muscle Milk during the years listed. I thought they tasted really good but sad to know now that they aren’t good for my health. I would like a refund for all the money I spent on those drinks. They’re expensive too.

  20. Keira Hand says:

    I have certainly bought the ready made beverages on several occasions, even within the last 6 months I recall purchasing one claiming to have 40g protein and a mere 220 calories, and now I am questioning this legitimacy and certainly would like to participate in this settlement claim.

  21. Dominick Balsamo says:

  27. Ron Wlaz says:

  33. Jorge De La Torre says:

    I drink lot plenty of Muscle Milk, as it is the only protein drink I have available on my college campus. I’ve drank bottle after bottle for the past two and a half years. I always thought this was a pretty reliable company, but now its making me have my doubts. As someone who watches their food intake pretty closely, this makes me not want to support this product.

    Thank you,

  36. YouPeopleAreStupid says:

    The people simply writing that you would like a refund, or would like to file a claim on the website are stupid. You think you can simply comment, “I would like to file a claim.”, and expect to get a check in the mail?

    Click on the link that says “CytoSport Muscle Milk Claim Form” and note that it says, “This is the only way that you may receive monetary reimbursement.”

    Some of you are lazy idiots.

    • nice guy says:

      I would like to file a claim too. I still drink their product, as I am a prepped, and got a lot for the big quake (or whatever). I think I should drink it now, since I learned that it is useless then.

    I would drink Muscle milk on occasion during lunch and at school where I couldn’t get a readily available traditional protein shake. In total I’d say I consumed some 5 or 6 bottles.

  42. Clayton Kline says:

    I consistently bought this product when training in high school during the latter half of the time frame.

  43. Robert Blakely says:

    I purchased well over $250 worth of muscle milk during this time. Pretty disappointed.

  44. Children says:

    Why do all of you think that posting a comment saying you would like to be refunded means anything? Apparently you never purchased any common sense…

  51. Michael Frick says:

    Drank way more than 60$ worth of the ready to drink beverages, would literally stop at 7-11 and pick one up after every workout. I believe they were over 3 dollars per and I easily drank over 100 of them in just one year for about three years total. I would definitely like to file a claim.

    I drank this for months not knowing any of this!

  75. J.Heinick says:

    My Fiancé and I purchase cases upon cases of MuscleMilk and Bars yearly. We both agree that we would like to be apart of this settlement. How could you tell someone something just to make your product look better. That’s so wrong it’s not even funny. I can’t tell you how much money we have spent on this stuff just to find out today that none of what the packages ever said was true. This company is extremely lucky nothing serious ever happened to my Fiancé or I. Or we would be doing way more than a class action settlement!!!!

  81. pamela says:

    When will they pass out the refunds.

  82. Dennis liles says:

    I purchased muscle milk products on a regular basis (daily). If you do the math I will never be compensated for what I have spent. Let’s see, three muscle milk bars daily with two shakes one in the morning and one in the evening after my workout for over a year. That’s a lot of dough

  83. Tiffany Cochren says:

    I was drinking it regularly, would like to file class action law suit

  84. Stacy S. says:

    I just happened across this and my family drinks RM Muscle Milk and have for many years – we buy the cases at Vitamin World.

  92. Anthony Calles says:

    I have purchased Muscle Milk and CytoSport products throughout my 30 years of weight training.
    I also got my son interested in Weight lifting and taught the importance of nutrition that goes along with a proper workout. I find it disheartening that a well known product that is supposed to encourage sports and fitness can totally misguide us. Please include myself and my son Dimitre in this suit. We both have accounts at Hi Health stores in Arizona as proof of our purchases.. Thank you.

  93. Dillon V says:

    I have purchased muscle milk within 2007 all the up to today very frequently. I must have spent roughly $800 within the above listed time frame. Even though it is been “resloved” I think I need to look into isopure.

  94. Terrence Lewis says:

    Hello everyone,

    I have on numerous occasion purchased the ready to drink beverage from after my fact in 2007 I was a advocate for the product not the harmful nature of the product. Every year mention I used to drink several bottles in the event I couldn’t make my own because of work. Even if nothing come of this Thanks for the heads up on the nature of this product. It was suggested to me by a bodybuilding friend who passed away in Iraq as we served together and I believed in what he believed in. I was new to the bodybuilding lifestyle.

    I used Muscle Milk protein for years until last month when I started having kidney problems and read that this specific protein contains a very high dose of arsenic and other harmful metals. One month after I stopped consuming Muscle Milk, I’m feeling better.

  97. Randy Wilson says:

    I purchased dozens of those drinks over those years for the gym. I can’t say I noticed if it helped or not. Mostly the vanilla and strawberry banana.
