Using Skimmed Milk as Supplement for Weight Gaining with exercise ?

I am plan to put on some weight through exercise and thinking to use skimmed milk powder as weight gainer supplement. There are many weight gainers products but I have high quality skimmed milk powder with 35% of milk protein. Now wants to know will it make a good weight gain supplement because if it is then will be lot cheaper than other weight gain product as well as will be reliable and authentic since I know the source of it very well.

Please give your advice.

I think it could be a great weight gain product because if its 35% milk protein then probably its one with 50% carbs and rest mineral etc..

But I have not seen anyone trying it as weight gainer because many people are adviced to use skimmed milk products when they want to loose weight. ..

Yes, you can use it but relying only on skimmed milk powder will not be a good choice, also add cereals, chickpeas in your diet if you are looking for weight gain.
