Gainer
The price is right. Taste is pleasant. Sort of thick with the recommended amount of water. 1 serving has me feeling completely full and I can eat a lot. I found I had to use a mixer for a smooth consistency, I wasn’t able to get it to mix well in the shaker bottle.

It does what it's intended to do.
Alright, when I read the other reviews for this product I invariably end up infuriated. This is a great product that provides 1500 calories at a relatively inexpensive price. This product will help you gain weight significantly faster than most other brands in the same price range. So everyone needs to stop complaining about the taste! Its not made to taste good its made to add some muscle to all you ectomorphs out there that can't gain weight to save their lives. That being said, I have tried every flavor and will provide a brief description of their tastes. Flavors: Chocolate: Second best of all the flavors that are available. It is appealing because its harder to get sick of chocolate then some of the other flavors they offer. Banana: By far the best flavor for this drink. Banana successfully tastes like a pretty good milkshake when mixed with milk but doesn't taste very good when mixed with water. Vanilla: An okay flavor, not as good as banana or chocolate but decent none the less. Strawberry: Avoid strawberry! It tastes horrible and for some unknown reason, it had a different and unappealing consistency compared to the other 3 flavors. So my recommendation is to alternate between banana and chocolate or to buy banana serious mass and add in some Optimum Nutrition protein powder which makes it taste even better. Again, I have gained 15 pounds using this stuff over the course of 2 months and my best friend has gained about 20 pounds in the same amount of time. It really does work if you take it every day. I generally take one heaping scoop in the morning with breakfast and one before I go to sleep.

Good gainer
If you're looking to add calories to your diet, these bad boy is what you need. Purchased the 12 lb bag for the value and I do want to note the serving size for this thing I almost double of other protein shakes, the scoop is enormous so it compares to a 6lb container of some other powders. I love this product because I only use one scoop instead of two and I like to make it in the blender and add ice cream or banana. I had some problems getting it to dissolve all of it in a shaker bottle so I opted for the blender method and with the vanilla flavor and adding some cookies and cream or cookiedough ice cream this is just delicious. Great way to add a massive load of calories to your diet . it has 50 grams of protein which is good but the kicker is the 1250 calories, again thats for a two scoop serving and the scoop is more a cup than a scoop. If you want a protein you can easily mix at the gym I suggest trying true mass by bsn, I like they're strawberry flavor. Otherwise for someone looking to bulk up, great product. Pros: Lots of calories The flavor is better than many, but it's a protein powder you're not drinking it for the flavor. (I tried the vanilla) Cons: the scoop is huge, I almost always use half a serving and use it to load on calories. It may take a while to get it to dissolve all the way in a mixer cup, specially if using the full two scoops. Overall great product, I keep this and a thing of true mass in hand when I'm trying to bulk up a bit during the winter, I cycle through the two based on how much I think I can down and so I don't get bored with the flavor. (also if I remembered to wash the blender, haha)

It's Working for Me - More Muscle Gain than Fat Gain
This product is working very well for me. I have been putting on mass faster than before using this product. I am not able to give figured on my weight progress due to the fact that I have not been keeping consistent track of my weight. I personally do not care how much I weigh as much as I care what I see when I look in the mirror. I could gain 10 pounds but just look like I gained fat instead of muscle. That's not what I want, and that's not what happened with this product. My arms have gotten noticeably larger (my girlfriend comments on them a lot lately), and I haven't even been doing isolation workouts for my arms. I have just been doing a lot of pushups and pullups. I have gained significant mass in my lats, and my chest has been getting bigger faster as well. I will give more updates as time goes on, especially since I will start back working out at the gym in order to do squats and other weighted workouts that I am unable to do at home. The main thing that you need to know with this product is that it is a mass gainer. While that may sound obvious, the reason I mention it is because some people complain about gaining fat around their belly while using this. If you want to keep the fat off, you can't just do mediocre workouts while taking this. You need to do high intensity cardio exercises as well depending how your own metabolism operates. I personally recommend looking up HIIT if you are not familiar with that type of training. I do not mind gaining a little bit of belly fat at the moment where my abs don't show perfectly, because I know that my primary focus right now is to gain as much mass as I can while taking this supliment. My metabolism is high enough that I am not gaining a lot of fat. I am noticing mostly muscle gain, but what little fat I am gaining around my mid section, I will be able to burn off with HIIT cardio in a short time after I bulk. Everyone has their own method. This is mine and it works for me. Feel free to leave me a comment if you have any questions. I may post progress photos later also.

With weight training and a very physical job I need a ton of calories (around 4000 a day) this mass gainer definitely helps, I find it tastes better with semi skimmed milk than water, and totals more calories consumed with 2 servings. The scoop is quite bigger, larger than what you'd used you put detergent in your washing machine, and the dose is 2 a day, you could just have one after a workout, but I have one at work around 10-11am which helps feel a gap well and being a shame is easier than food or snacks. I got the vanilla one, it tastes a tad different to the normal whey protein by ON, sweeter maybe but after a first few tries it's fairly nice, I don't use a blender just a shaker ball, and about 600ml of milk, it does a clump a bit and needs several shakes between a few swigs. Put the milk or water in first (this is common knowledge) but try and shake it hard/drink quick after dropping the powder in as the longer it fits the more it'll clump at the bottom and it's not fun trying to consume the gloop at the bottom, messy. Or just don't be lazy like my and blend it, might come out better.

Je prend ce produit depuis 8 mois maintenant. Je suis ectomorphe et j'étais très très léger(54 kg pour 1m80) J'ai modifié mon alimentation est intégré le produit dans ma routine alimentaire, je fais maintenant 70 kg. ~15 kg ! à savoir que le produit est là pour aideret ne doit pas être le seul aliment, je fais: Repas kcal estimées Collation matin ~800 kcal Déjeuner ~900 kcal Shaker après-midi 1268 kcal Dîner ~900 kcal Shaker soir ~1268 kcal Attention, le shaker a besoin de fibres + lipides car les glucides rapides (le shaker) provoque un pic glycémique (rajouter carotte,noix et huile de colza avec) Enfin, 2 fois par jour est la limite. Même parfois il faut se contenter d'un, sur le long terme et sans variété dans l'alimentation ça peut causer éventuellement causer problème Bref, ce produit m'a aider à atteindre un poids que je visais depuis longtemps ! Avec la muscu bien évidemment (je prend deux cuillères + eau pour le shaker) je recommande ! Enfin, j'ai regardé, et : Inconvénients : Élément Analyse Maltodextrine en 1er ingrédient Très haute charge glycémique → peut provoquer des pics d’insuline si pris seul (sans fibres ni lipides). Pas idéal si tu es assis ensuite. Édulcorant : sucralose 🔧 RAS en petite quantité, mais à limiter sur 2 shakers/jour. Impact possible sur microbiote. Trop de protéines d’un coup (50 g) ⚠️ On n’absorbes pas tout si tu le bois d’un trait → à fractionner sur 20–30 min ou compléter avec fibres/lipides (banane, avoine, huile de colza). Avantages : Élément Analyse Calories très élevées ✔️ Excellent pour une prise de masse propre chez un ectomorphe. Glucides (256 g) ✔️ Très haut, à base de maltodextrine → excellent pour refaire les stocks de glycogène post-entraînement. Protéines (50 g) ✔️ Mélange de whey, caséine, albumine d’œuf → très complet, absorption lente et rapide. Créatine 3 g ✔️ Bon dosage, efficace pour la force et volume musculaire. Micronutriments Contient toutes les vitamines et minéraux essentiels à 75–100 % AJR, ce qui est rarement aussi bien couvert par un gainer. Goût VANILLE J'aime bien
