Optimum Nutrition MASSE SERIEUSE 12 lb.

This super high quality mass gainer really helped me put on some serious size within the past 2 months. Especially for a person who doesn't have a big appetite it really helped me to get in my calories for the day. Optimum Nutrition is the best

I did some trial and error and figured out that I start to gain mass at 4000 calories per day consistently. The only problem is that eating and cooking enough for 4000 calories can really be a drag. Luckily mass gainers were invented and Im taking full advantage! Great price for 12 LBS of muscle inducing power-powder! I sometimes have more than 1 serving per day especially the days when I'm super crazy busy. Great job ON! I'm officially a client for life!

I've always had a lot of difficulty putting on mass. It's my body type. I noticed that using this product keeps me way fuller and stronger. I bought 2 bags of this product 2 months ago and I just finished them both about a week ago. I'm happy to announce I gained 5 solid pounds which I couldn't be happier about. I kept my calories high at just about 4000 cals per day and this product made hitting 4000 cals doable. It made it possible for me since I don't have a big appetite. ON = quality for sure!

This product is what you want if you're looking to pack on muscle. At 1250 calories per serving, you will be anabolic. This product works very well

Quality gainer tastes great
