    Complete Lean Mass™ is perfect for anyone who wants to add muscle mass, but at the same time avoid adding unnecessary body fat. Complete Lean Mass™ is packed with high quality protein and carbohydrate sources, avoiding sugar-based carbohydrates and unhealthy fats found in most weight gain supplements. All of this ensures that Complete Lean Mass™ promotes only quality weight and muscle mass – all in one convenient and great tasting formula.

    Complete Lean Mass™ contains 338kcal, from 34g protein and 34g carbohydrate per serving and only 5g fat, which is naturally occurring in the oats and whey.


    • Contribute to the growth in muscle mass
    • Contributes to the maintenance of muscle mass
    • Rich source of BCAAs
    • Added Glutamine Peptides
    • Optimal 1:1 ratio of protein to carbohydrate
    • Low GI Carbohydrate – stable blood sugar
    • Slow and Fast Release Protein Blend


    Complete Lean Mass™ contains only the highest quality ingredients. Whey protein concentrate, milk protein concentrate and egg white powder provide a dual, fast and slow release protein blend. The carbohydrate comes from low GI ultra-fine Scottish oats, supplying sustained energy and a great source of fibre. There is zero maltodextrin or dextrose added to this product, unlike most weight gain supplements.

    Further to this, BULK POWDERS™ specify the exact amounts of each ingredient included within Complete Lean Mass™, right down to the ratio of each protein included within the Slow and Fast Release Protein Blend.


    Slow and Fast Release Protein Blend

    A protein blend of 40% whey protein concentrate, 40% milk protein concentrate and 20% egg white powder, delivers a complete collection of amino acids at different speeds of absorption. All three protein sources are popular in their own right for strength athletes. And, unlike many other brands, we are happy to detail the percentage contribution of each protein source – we have nothing to hide and are proud of this fact!

    Glutamine Peptides

    Glutamine peptides (3.8g) are an extremely popular source of Glutamine to use alongside protein. Glutamine has been included in peptide bonded form for superior absorption.

    Ultra Fine Scottish Oats

    Oats provide a healthy source of carbohydrate that fuel the body with a sustained release of energy and provide added fibre.


    Complete Lean Mass™ has been designed specifically for those trying to increase muscle and/or weight, but who don’t want to gain unnecessary fat, or those who prefer a slightly lower carbohydrate content than is typically seen in weight gainers. The calorie content of 338kcal per 85g serving sits perfectly between a protein drink and the 500kcal+ that is commonly seen in weight gainers. If you’re a real “hard gainer” looking for higher calories, then Complete Mass™ would be a more suitable choice for you.

    Great taste! Review by AAR
    The best taste compared to other protein shake products!
    Fast delivery of the product. (Posted on 06/05/2017)
    great shake Review by darthdessie
    lovely clean product, great content.
    easy to drink, can taste the oats but I like that.
    easy on the stomach too. (Posted on 18/05/2016)
    Best Flavour Protein. Love it! Review by RiotReiben
    After trying many different proteins from a variety of protein sites I have finally found a protein I can stomach! The chocolate flavour complete lean mass is by far the best tasting protein I have ever tried.

    The closet to a real chocolate milkshake I have drank, the consistency is not too thick nor too watery and its mixability is great (Only time I get lumps if through not giving it a good shake). It's the only Protein shake that I can stomach early in the morning and post workout and actually enjoy drinking.

    I have not been drinking this particular protein for long so I cannot comment on it's muscle building ability although with it's high protein content I'm expecting to have no problem with achieving my goals through this drink. Highly recommended! (Posted on 03/02/2016)
    good product Review by Logan
    would recommend to anyone trying to pack on a bit of muscle. worked wonders for me. The Scottish oats gives it a bit of a texture, and makes it slightly harder to mix, but on the face of things you really can't complain. great shake, great results, great taste. (Posted on 23/06/2015)
    Great product, good taste. Review by The Jackal
    I've been using this for a few months and really like it.

    Firstly, it delivers on the performance side and I've noticed marked improvements in my body.

    The chocolate flavour tastes pretty good compared to most supplements, but I've been mixing it with milk rather than water to give it a bit more flavour and creamier consistency.

    Would recommend. (Posted on 27/04/2015)
    Decent shake Review by Cillian
    When taken do not eat anything after, shake is filling and you get a sicky stomach if you eat after drinking it. But seems like a good shake, gains will start kicking in hopefully! (Posted on 17/04/2015)
    Love it! Review by TAYLOR
    I've been taking Lean mass for about a year now and i love it. The chocolate flavour is great, it's not too sweet at all, and can genuinely say tastes as good as a nesquik.

    I was taking complete mass before but wanted something with a little less carbs to keep me lean and this has definitely worked wonders and helped me gain clean weight

    I actually enjoy taking this shake daily.

    Have been recommending this to all my pals. (Posted on 11/02/2015)
    Great Review by adam
    Works well! (Posted on 23/11/2014)
    More Flavours please! Review by David
    When is bulkpowders going to add more flavours to this range? The Complete Mass already has banana, chocolate peanut and chocolate cookies. C'mon bulkpowders, get a move on! If anyone else want more flavours, voice your vote on here! (Posted on 26/10/2014)
    Great Supplement Review by Hugh
    This is a great tasting supplement in chocolate flavour. It's sweet, but you can just water it down a little more if you find it sickly. It ticks all of my boxes as far as macros go (recovery and growth), and it really is a great product for anyone who wants to add some size to their frame and stay away from the hardcore mass gainers. Highly recommended! (Posted on 13/10/2014)
    Good but flavours Review by Aisha
    I do like this product...and it is very filling. However, I am not a fan of chocolate and I found the strawberry a bit sickening....that is just my preference though. I just wish there was mare flavour variety....or even just an unflavored option. (Posted on 11/08/2014)
    Good Review by Ant C
    Just finished 5kg of strawberry, mixes very poorly even in my blender(wouldn't mix at all in my vortex shaker ) it is a very gritty texture when drunk & tastes like crap. Just letting you know my honest opinion , I will be ordering the chocolate one to try hope that is better. I also ordered 1kg of peanut butter that on the other hand was amazing ! (Posted on 08/06/2014)
    Almost 5 star Review by David
    This is a great product except that at the end of drinking the shake, there is always a mouthful of gritty oats that isn't fine! Otherwise I would have awarded it five stars. (Posted on 29/05/2014)
    a***** Product Review by Rees-MMA
    This has got to be the best protein powder out there! I thought with it having carbs, I would put on weight, I WAS WRONG!!! If you work out regularly you cut fat and build muscle plus you recover alot quicker so better workouts all round. (Posted on 22/05/2014)
    Good stuff Review by John
    I really like this product. It's a little sweet (Chocolate flavour) compared to other protein I've used, but you get used to it. It tastes like a more like a milkshake than a protein shake.

    I use it post workout, for the price you won't find better. (Posted on 27/03/2014)
    Brilliant Review by Steven
    Been using this for over a month now, mixes fine, the chocolate is good in taste but could be a little less sweeter. Since using this product I've felt an improvement in my training and it has reduced my weight and gained muscle. Would recommend to anyone who wants to improve their lifestyle... (Posted on 10/03/2014)
    Clean, lean bulking Review by Peter
    Having put on a little too much too quickly with the standard mass gainer, I opted for this. It tastes as good as and has a much tighter carb:protein ratio.

    Good steady gains which hopefully won't require too much of cut when ready.

    Only problem it that it tastes so good, drinking oats too quickly can lead to indigestion. Great stuff! (Posted on 29/01/2014)
    First shake down... GREAT TASTE! Review by O.R.P
    First shake down... GREAT TASTE AND REALLY FILLING! Chocolate flavour definitely is the way forward. However if it was just 1% or 2% less sweet I'd be happy.

    Great shake, great customer service, now all that's left is to see how it helps my progress in the gym! (Posted on 24/12/2013)
    Good Review by Artur
    I've done 2.5 kg in one month after workouts. Weight has remained exactly same but definition of muscles more visible. I did a lot of cardio sessions but still look like fat down muscles up. Can not complain. (Posted on 16/11/2013)
    Chocolate flavour Review by Gavin
    I took a punt and bought 5kg of this stuff. My current goals are fat loss and muscle gain.

    Just had it for the first time now for breakfast. Absolutely delicious! Nice consistency. Love it! Surprised how filling it was actually.

    My rating is based purely on taste, after one shake obviously I can't comment on results. But other reviews should give an indication of that. (Posted on 01/09/2013)
    Solid product Review by Daniel
    I've started using this as part of a weight loss / muscle gain program I have been following. The product mixes well, tastes decent, and if you are lucky get a slight chewy bit of oat sometimes to liven the shake up ! Much prefer chocolate to strawberry personally. Easy to drink, and has had the desired effect for me, bodyfat is reducing (with hard work) and I have a much firmer, toned physique. No side effects, and doing the job! 5 stars for me. (Posted on 09/08/2013)
    Very Convenient Review by Cormac
    Very convenient product for getting carbohydrates and protein, tastes ok. (Posted on 08/06/2013)
    Complete Lean Mass Review by D
    Personally I love this stuff... chocolate is nice with skimmed milk and totally does the trick. Thanks guys!!

    Great formula. (Posted on 30/05/2013)
    Solid Product Review by Jake
    I bought a 5kg pouch of this back in late November to help me add some protein & clean carbs to my diet without spending huge amounts on food. I have just finished the pouch 2 days ago, having 3 shakes a day on training days, 1-2 on non-training days -meaning it has lasted me nearly 4 months! Superb value for money, great taste and quality ingredient profile - really helps if taken pre and post workout and all my lifts have increased in strength since adopting this protocol with CLM. Will definitely be purchasing again in the near future :) (Posted on 21/03/2013)
    Avoid Strawberry Review by Alex
    First impressions are that this product is nutritionally very good. Only been using for a week so can't comment on results yet.
    Would suggest choosing chocolate as I chose strawberry and don't find the taste great. (Posted on 27/01/2013)
    Great taste and mixing Review by Jordan
    I bought the 5kg Chocolate Cookie flavour.

    And oh my god, it's just delicious, it mixes perfectly with water, it tastes perfectly good, and It gives great recovery.

    It's a great product, the only issue I had was with the packaging (5kg), it had a small hole in it making the product falling on my floor. Fortunately I fixed it up with duct tape.

    Anyway, 5 stars deserved, I'll buy again. (Posted on 16/11/2012)
    Odd pricing Review by Pete
    When you compare this to the Mass gainer its technically identical but the dosage is smaller, yet the price is an extra £5, can you explain please?
    good product, complex carbs but a little strange pricing. You could just buy the mass gainer and have smaller scoops.

    Note from BulkPowders: Thanks for the review Pete. Complete Mass contains 29.9g protein and 49.1g carbohydrate per 100g. Complete Lean Mass on the other hand contains 40.3g protein and 40.2g carbohydrate per 100g - making Complete Lean Mass higher in protein and lower in carbohydrates. This is where the additional cost comes from and explains why it is more suited to someone looking to add lean mass. (Posted on 24/08/2012)
    Too sweet Review by C Smith
    I purchased the strawberry mass gainer and I was disappointed with the taste. The taste was way too sweet and artificial for my liking. I have tried mixing with milk as well as water. Due to the sweetness I have been forced to purchase unflavoured whey to mix it with.

    Note from BulkPowders: Thanks for your review! We feel that a 1 star rating based purely on taste is a little harsh, but we will take your comments oregarding the sweetness on board also! (Posted on 12/08/2012)
    Taste ok but better mixed with bit of Peanut Butter Review by Graham
    Excellent Delivery.

    Choc Lean Shake

    I have made some gains thanks Lean Protein shake :)

    I will try Strawberry flavour next time :) (Posted on 29/06/2012)
    We'll see:) Review by Arvydas
    The first thing, extremely quick delivery!
    Taste is great (I ordered strawberry) and it's mixing very well.
    How it's works, I`ll see in a few weeks:) (Posted on 23/05/2012)
    buy now!! Review by dean
    it works! piled on 2 stone using this powder. awesome with home made protein bars too. (Posted on 27/04/2012)
    Choc cookie Review by darren bray
    Mixes well, tastes very nice just the right hint of sweetness. And has good macros. (Posted on 11/04/2012)
    Fantastic Product Review by Richard Williams
    Great product. Has just the right ratio of good quality carbs and mix of all types of protein to gain lean mass. Had previously been mixing oats with whey protein seperately but no need to now this product is on the market. Comparable with Sci-MX Lean Grow or USN Muscle Fuel but much better value. Strawberry flavour tastes great also! (Posted on 11/04/2012)
