Muscle building Gainer
Brilliant weight gainer for muscle building. Has a great protein profile. The quality of the product is very high and well packed. Although it has huge serving portions you can always adjust to what you need to meet your requirements.It dissolves well and tastes really good compared to a lot of others I’ve tried. It has a smooth texture after just a few shakes in a bottle and goes down nicely.

Good value and effective
Excellent product, good price.Other similar products I have tried have a sickly sweet synthetic flavour, more expensive and seemingly less effective.Nice taste that isn't overpowering or very sweet. Good consistency when mixed (I don't mix it very well or shake that much and the few clumps I get aren't at all off-putting)Despite the calories and well rounded ingredients I wouldn't think of this as a replacement and am pleased to see that it isn't marketed as such. Rather, if you are training or just generally busy with stuff this feels like an additional surplus/boost to improve your growth and overall health. I am not a big fan of protein powders, meal replacements, pre-workout etc and this feels like it sits somewhere nicely inbeteeen those.I would highly recommend this product to anyone that wants a well rounded powder to supplement their diet.

Please read review. Nice taste and mix but questionable ingredients
PLEASE READso as a weight gainer shake , mixability and taste wise I think it's great.Unfortunately the main ingredient is maltodextrin . Which they say is a carbohydrate source , but in fact your body sees this more like a sugar and this spikes your blood sugar way more than table sugar. In fact almost double.This item for that reason will help you gain weight , but I doubt much of it would be muscle.I've given 4 stars because it's not bad , but if you are informed on ingredients you will understand maltodextrin is one you are best to avoid.Dr Berg does an interesting video on it if anyone would like a dr's opinion.

Bought this as I couldn't get my normal order. This shake is awful! Got the chocolate flavour, it does not mix in a shaker. There was a good half a scoop clumped in the bottom. I put it in the blender and obviously it sorted it. Taste test time. Wish I bloody hadn't. It tastes somewhere between plastic and petrol. DO NOT WASTE YOUR MONEY.I will deffinetly pay more attention as to when I'm running low on my usual stuff.Fyi - MUSCLETECH MASS TECH EXTREME 2000 is the one to go for. Mixes perfectly and tastes amazing. 10/10

Tastes bad but effective
Tastes awful, makes you very bloated, however should be good in the long run with 1000 calories and 60g of protein, just do not drink before a run

Impressed. Notice results
This is a great product. Has good flavour without to much sugar. Mixes well and It disgests really well. Can have with milk and i have to say the flavour is really nice. Water is just as good to definatly worth the price.Ive been taking for few months and have noticed a difference. Ordering the 5.2kg one will get most for your money.

Fantastic experience overall. Will recommend to friends and family.
For a full serving mix 300 g (approximately five heaped 60ml measures with 700 ml water in a suitable shaker cup or blender, mix until smooth. This product is intended for adults performing high-intensity exercise. When just starting with this product, you may find it beneficial to begin with half the quantity before slowly increasing to the full serving in order to make it fit into your personal calorie plan. Consume Instant Mass® Heavyweight between meals to maintain a positive nitrogen balance, or drink 20-30 minutes after a workout for optimal results. Alternatively, take Instant Mass® Heavyweight 45-60 minutes before bed to contribute to muscle maintenance overnight. Once mixed, consume the shake immediately and don't leave to stand. For a shake that is more calorie-heavy and creamier, try the product with semi-skimmed milk.
