extreme hard gainer

Ok i am skinny, I used to be quite big, never touched roids before and dont intend on doing so, want to be all natural. Events in my life a few years ago caused me to loose alot of weight but now I am on the path to getting big again. I have been taking this hard gainer extreme for about 2 weeks nearly 3. I am eating quite abit more also, I have definatly noticed a difference and I have had comments from friends who I seen over the weekend (Who I havnt seen for about 5 weeks) that I am looking more defined in my chest and shoulders...definition is not what a I want - I want to bulk but it is very early days from me starting this stuff and it is definatly helping me....I am very exited for a few months down the line....I also have the protein 5kg aswel, Taking 1 hard gainer extreme/ 2 a day on some days, with the whey impact protein once every couple days with usually two big meals and some nibbles through out the day. I also do a high calory burning job which is roofing. So this is helping me so much thanks guys ! Taste is beautiful I have chocolate , Mixes up very fast, have had some bity bits in it but doesnt bother me, When my 5 kg is done I will be getting more :D

Extreme for a reason

Tip : Put your Water or Milk in your shaker first then add your powder. If it's still a bit lumpy then next time add 1 scoop, shake then add another and repeat. The most productive way I find to gain weight is to; Eat breakfast then have my 3 scoop shake. Then have a high protein and carb snack (for example, 1 1/2 tuna or chicken sandwich, 3 rice cakes) 3 hours after with 1 1/2 scoop shake. 3 hours later, have your high protein and carb lunch again with 3 rice cakes and 1 scoop shake. 3 hours later, have your high protein and carb snack again with 3 rice cakes and 1 1/2 scoop shake. Intense Workout 1 scoop after Half an hour after workout, another snake but now 3 scoops Now this isn't easy once you start but the more you do this the easier it gets, you have to be strict though, stick to it. You will be consuming over 1,300 calories per day in your Hard Gainer alone so it's important your are getting an extreme workout to go with this, this regime will allow you to do cardio whilst gaining muscle, cardio is the best way to workout your most important muscle - your heart so do not neglect your cardio. The healthier you heart the quicker oxygen get's to your muscle and helps recover quicker. Follow these and you will notice within 10-14 days the muscle gained.
Goes Well With:
Water or Whole Milk

Taste to sweet

The extreme hard gainer is a good product and does was it is supposed to. The only problem I have with it is that it tastes way to sweet!!

Helps if you're skinny

This stuff is really good if you're a guy like me that struggles to put on weight and doesn't eat enough food throughout the day. Also if you feel like you've plateaued with the normal Whey protein stuff and you feel like you haven't been seeing improvements for a while then try this! It really helps getting the extra calories that you need to build muscle especially if you're find it hard or tiring trying to eat loads in the day. The strawberry cream ones pretty nice actually, 3 scoops of it in a large shaker filled with water. If you were on the Whey protein before try this stuff instead of it, it fills you up but don't reduce what you're eating because of that, it may be hard for a week or two but thats what you've got to do for them gainsss!

It works

I've always struggled to gain weight. I have been using this hard gainer extreme and I am seeing results. I put in 60 grams of oats, mixed berries, 1tbs peanut butter, 1tbs coconut oil, 1tbs Greek yogurt and 3 and a half scoops of hard gainer the whole milk. It works out to about 1500 calories per shake.

Great for beginners

This product is very quick and easy to make. For myself it helped me get the nutrition I needed to bulk up. I bought 5kgs worth of this product and I helped me gain 6kg over 2 months. It is important that if you are going to be taking this product you only consume it if you are actually active. If you start to just use this as a meal replacement and you aren't getting enough steps the carbs in this will just make you fat. In my case it helped me gain a bit of weight as before I started using this I was 55kg and now I am 61kg. The amount of protein in this has helped me get the protein I needed to develop some muscle. Definitely a recommendation for someone that is maybe a little lazy and doesn't like cooking and maybe struggling to actually eat enough calories in a day. Definitely changed my life for the good
Goes Well With:
200-400ml water 100-200ml skimmed milk Or 150-300ml water 200-350ml semi skimmed milk

Read full review!!!

I’m a 21 year old male, 5’8 and my whole life been skin and bone. Recently I’ve started to use this and go gym and within 2 weeks all my family and friends have said to me they can already see I’m getting bigger. However if your like me I struggle with the taste of ANY protein shake no matter the brand of flavour (even this one) the solution is SMOOTHIES! I didn’t like this powder at first when I tried to drink it with squash. I used in a smoothie and I can’t taste it now I drink 2 a day. It definitely works 100%. This is my first ever review for any site but I thought I have to help anyone else who’s in my shoes. I use a nutribullet blender to make my shakes and in the cup I put in; 1 banana  2 strawberries  Handful of raspberries  Big handful of blueberries  Handful of walnuts  Handful of hazelnuts  1 tsp of honey Almond milk until it reaches top of the fruit. 3 scoops of protein shake. Hope this helps someone.

It works!

I've been using this product for over a month now, and honestly, it works! Ever since I started University, my stress levels risen tenfold. I was almost always stressed out due to University work and quite a few personal problems. This all caused me to lose significant weight. My friends in University noticed how skinny I've gotten, and when I met up with a good friend who I haven't seen for over 3 years, the first thing he noticed was my weight loss. It didn't feel good, at all. I'm still stressed out a lot lately, however I told myself that I need to do something to at least lower my stress levels. So I decided to exercise again more often, but I needed a mass gainer since I don't gain weight easily, and I'm a massive eater for my size. My friend suggested to check out this website, so I bought this. I got the chocolate smooth flavour, which, in my opinion, was a lot sweeter than I expected. There are also 'bits' in it, however I got used to it. However, my brother and my cousin tasted it a little and they said it tasted good, so I guess it was just my preferences in taste. I take this straight after workouts, 2 times a day, morning and afternoon. I have gained noticeable weight in 1-2 weeks, and now over a month of taking this mass gainer, I look a lot more healthier and I've gained some muscle now. In conclusion, this product really worked for me in terms of gaining mass and muscle to bulk up. I will buy this again once my current one runs out.

Been using this for 1 year+, its the best of the best

Impeccable service yet again from My Protein, I ordered late Sunday and Tuesday morning I have my products! For value & effectiveness this product is perfect, Ive seen some great gains from this and being 6'0 and pretty slim its helped me a lot. It mixes and tastes really good (smooth choc), I throw peanut butter, bcaa and nutella in to make it 1000+ cals for the gainzz. I have seen a lot of reviews saying it doesnt mix well and tastes gritty - *shake harder or make sure your protein is in a dry mixer so as not to stick to the bottom (mistake I make every other day unfortunately) *it is not prosecco, its protein power with water/milk, it is not going to mix to Michelin star perfection so stop moaning about the 'gritty/sandy consistency'!!!!
