Ultimate Nutrition Prostar 100% Whey Review

I recently bought a 5.28lb pack of Ultimate Nutrition Prostar 100% Whey Protein Powder (Chocolate Cream flavor); here is my review of it, after using it for a few days.

ultimate-nutrition-prostar-100-whey I initially thought about buying it, because thanks to a discount coupon, I was getting 5.28lb pack of Prostar 100% Whey for Rs. 4,734. In comparison, ON Gold Standard 100% Whey was going to cost me Rs. 5,758 for 5lb pack.

So not only was I saving more than 1k with Ultimate Nutrition, I was also getting 0.28lb more protein powder. This roughly translates into 6 extra servings, per container for Prostar 100% Whey at a cost of Rs. 59.17 per serving vs. Rs. 77.81 per serving cost of ON Gold Standard 100% Whey.

For someone who uses Whey Protein Powders regularly, this is a substantial saving and the fact that Prostar Whey actually has 1gm more protein than Gold Standard, just makes the deal seem even sweeter!

Since both Ultimate Nutrition and ON (Optimum Nutrition) advertise similar ingredients for these protein powders, I can only assume that both are at least comparable, if not similar.

Ultimate Nutrition Prostar 100% Whey vs. ON Gold Standard 100% Whey

Ultimate Nutrition Prostar 100% Whey vs. ON Gold Standard 100% Whey

Of course this is where the similarities end.

While ON Gold Standard 100% Whey is easy to mix in cold milk/water, Ultimate Nutrition Prostar 100% Whey takes a bit more effort and even after that, it doesn’t completely mixes and leaves a few lumps in the end (using the same shaker).

Add to that, even though Ultimate Nutrition Prostar 100% Whey uses the same artificial sweetener (Acesulfame Potassium) as ON Gold Standard 100% Whey, EAS 100% Whey and BodyTech Whey Tech Pro 24, it is a lot sweeter than others. And that along with the lumps, makes it difficult to consume.

Whether or not I end up ordering another pack of Ultimate Nutrition Prostar 100% Whey is dependent on me getting used to its taste in the long run. Add to that, I am a bit worried about higher levels of artificial sweetener in it, especially since I am consuming an extra serving of it each day to make up for abstinence from eating eggs (due to shradh and navratri.)

Thankfully I have a 2lb pack of ON Gold Standard 100% Casein coming in a day or two, so I would end up consuming one serving of it daily and 2 servings of Prostar 100% Whey and that would hopefully level things out.

Overall, I feel Ultimate Nutrition Prostar 100% Whey Protein Powder is best value for money at the moment, as long as you can overlook that extra sweet taste and inability to mix fully in cold water/milk.


  1. Well its a comment not related to review of whey protein ,
    i have consumed the whey protein some 5 years back and i felt good initially and energetic , was doing gym greatly but after some months i noticed some health issues like irritation in skin , bowel problems , tingling pain in my bones and i cannot stand for more and was helpless.
    went to many doctors but no help all tests were ok except uric acid , after few months of failure to get healthy i was asked to go for Thyroid test and it was found i am hypothyroid
    contacted Endocrinologist and they told me its very rare that a male is hypothyroid as they dont have triggers like girls to be hypothyroid , they were completely against the use of Supplement foods and suggested for natural products as they can trigger hormones .
    now taking pills for thyroxine from the past 5 years.

    so i suggest you to eat, drink milk products to get your protein intake,
    milk butter has good amount of whey protein

    • That’s quite bad Nitin. Btw did you take Whey protein or did you take mass builder or weight loss supplements as well?

      Asking because normally Whey protein powders do not contain anything else, however things like mass builders or weightloss supplements do have things which mess with hormones.

      I am an eggitarian on a diet, so it is impossible for me to meet my protein goals in limited calorie diet, unless I start eating couple of dozen egg whites each day or take protein supplements.

      I have been using whey protein powders for 3 years now (off and on) and continuously for almost a year, no issue till now. If anything, my health has improved significantly since earlier this year and I attribute quite a bit of that to increased protein intake (in which whey plays an important role).

      Oh yes, butter has 80% fat and 0.5% protein, it is also high in cholesterol.

      • I agree with Yogesh here, been using ON Whey continuously for 1 year now, along with Creatine. No side effects, but health has improved tremendously.

        For an eggetarian like me and Yogesh, it is nearly impossible to get that level of protein from our regular meals, unless eating is taken up as a job! My experience with protein has been extremely positive till now. I do drink 4-5 liters of water daily as well, that helps in keeping everything up and running too.

      • Good point Akhil. It is extremely important to drink plenty of water to keep yourself well hydrated and help remove the toxins from the body.

    • Bro u should have drank 5-6 liters of water and also check the authenticity of your product you would have taken some adulterated protein powder also go for genuine one

  2. Which is the best Ultimate Nutrition Prostar 100% Whey Or Optimum Nutrition Whey protein Tell me fast

  3. Never Buy Ultimate Nutrition Prostar,..!!! the official Importer Paradise Nutrition is selling fake, underweight dubious product.I ordered a protein Supplement from Amazon Ultimate Nutrition Prostar( I had ordered this product 3 times before as well from healthkart so I know much the content should be and what is the taste like) the official importer of this protein is Paradise Nutrition who tried to test the intelligence of the customer by sending an underweight product the product delivered was underweight more than half of the powder was missing. After numerous angry mails and calls to Amazon and the seller, and after threatening the seller with legal action, the seller agreed to a hand to hand replacement. A hand to hand replacement was done after almost 2 months of raising the issue. The seller sent a boy from his Delhi branch to collect the defective product and hand me the replacement. The boy opened the product in front of me( the defective one) the freshness seal was missing on the container and there was a duplicate seal in the lid the boy then called his Delhi office senior and they said they could not replace the product. I called the seller based in Mumbai again and threatened them with legal action the seller then readily agreed to hand to hand replacement, the replacement was done but the replaced product although does have the original seal but it has a foul smell and taste is bitter, I had asked the seller to provide me with the invoice for the replacement but he is not willing to do so. Now I am seriously considering legal action against the seller and I have seen there are many other customer’s who have faced similar concerns.

      Hello James this is Bunty Paradise Nutrition is the only authorised importer of Ultimate Nutrition Prostar 100% Whey Protein..You should have checked the hologram of Paradise Nutrition before accepting the product..Because genuine Prostar Whey contains the Paradise Nutrition on it..If you visit Ebay and check the Ultimate Nutrition Prostar Whey product listing you will find the Paradise Nutrition hologram image alongside the image of the jar..This proves the product being sold by the seller is genuine..And lastly never buy any supplements from Amazon..Most of the sellers at Amazon are dubious..Go to for further information

  4. Sanjay Mukherjee says:

    Who sells genuine On products in India. There are lot of adverse comment in Amazon against the official importers in India.

    Very frustrating indeed.



      • If you see ON’s site,They have a list of their international importers there. For India, 4 importers are mentioned there. One of them is Neuvera ventures. You can buy a genuine product from their site. I generally order it from they offer discounts and the product has neuvera hologram and a code which can be verified online on neuvera’s site for genuineness

  5. Vivek Khurana says:

    Does ON 100% WHEY GOLD STANDARD contain egg.
    Also, what about Ultimate Nutrition Prostar 100% Whey in terms of egg content.
    Actually, I am pure vegetarian so avoid egg and any kind of meat. All milk based contents are OK to me.

  9. Thanks, that was exactly my thoughts.. Finished my ON 5lb tub and now got UN 5.28lb and taste is too sweet.. Just need to get adjusted else I guess it’s a sweet value for money

  10. Hello Yogesh,

    read your post felt nice. I consume nitro tech protein but its seemz very costly wen we include are diet. So is it good n affective to ultimate nutrition .

    Awaiting for your responce..?

  11. I have started gymming since a month and i have been advised by my trainer to get this prostar protein. But my parents wants to know if there’s any harm in using this product or not? I am confused. Can you help me out?

  12. when to take this Whey Protein Powder… Before or after workout?

  13. I was a regular user of Ultimate Nutrition Prostar until recently, I faced some issues with them trying to shortchange me by selling an underweight product without the original seal, after threatening with lawsuit, I got a replacement, but the taste of the protein is really bitter even with milk, its like there is creatine added to it in large quantities, I am thinking about getting a small sample checked. Just a piece of advice don’t use Prostar, the company has filed for bankruptcy in the states and the importers in India are trying to shortchange the customer. I strongly believe don’t compromise on quality even if you have to pay extra.. If flavor is not an issue for you, you can check this website Nutrija.

  14. I had bought ultimate nutrition prostar.I have taken almost for one and half month and completed 5 28 long it will take for muscle building

    • Protein does not builds muscles. It is just a nutrient. Muscles are built with proper and regular exercise, and each body reacts differently to it and takes its own time to build up.

  15. Anil Thekkut says:

    Hi Yogesh, your article is good, I am 47 years and recently started going for cross-fit, i brought ultimate nutrition prostar 100 whey protein recently and would like you to suggest the daily dosage and timing.

    • Hello Anil,

      You really have to calculate your protein requirement based on your body weight and whether you’re trying to lose weight or trying to gain muscles. Whey supplements should only be used to supplement real food i.e. if you’re eating enough protein rich food, you will need to take a single serving. However, if your diet lacks protein, then you might need to take 2-3 servings a day.

      Best time of day to consume good quality protein is early in the morning or after an intense workout. That is when your body needs protein the most.

      Hope it helps :).

    • Are you having it in water or with milk? Try it with milk (unless you’re lactose intolerant, in which case avoid Whey) and see if it helps. If not, skip it, it looks like it doesn’t agrees with your constitution and it is best avoid taking it.
