Good protein

Review for Maximuscle Promax Lean 1.2kg by Anonymous Reviewer on Nov 10, 2013

Bought 2 tubs initially Choc/Strawberry taste great and easy to mix unlike some others I have tried. Seems to be making a difference since I started taking it and I feel that I've gotten somewhat leaner since taking this protein (since I don't take any other products). I've just ordered 4 more tubs in all other flavours, lets see how they taste.

Review for Maximuscle Promax Lean 1.2kg by Chris from Bicester on Jun 14, 2013

This stuff is amazing! 3 weeks on my fitness levels as risen significantly, i have lost just over 2 inches around my core of fat and muscles have started appearing around my shoulders and arms. I have used the shakes and bars replacing breakfast and lunch with a shake and having a bar in-between when working out. Now I’m riding 100k bike rides and doing 40mins straight insanity works outs!

Review for Maximuscle Promax Lean 1.2kg by Stuart from East Lothian on May 30, 2013

Feel great since I started using this whilst undertaking a rigorous fitness regime. Tastes great too and prevents hunger and therefore snacking. It is a little expensive whether you view cost by comparison or the actual pounds and pence required on the upkeep but I feel the benefits far outweigh the negatives.

Seems to work well.

Review for Promax Lean by Anonymous Reviewer on Apr 19, 2013

Started using this product yesterday along with thermabol as a meal replacement. I felt so alert in the gym and managed to do 20% more cardio than usual. Not a fan of the taste but if you want a good tasting milkshake just go to McDonald's. Weighed myself this morning and I'd lost 4lb which I was amazed at. Bit pricey but will definitely buy again!

Promax Lean Review

Review for Promax Lean by Sebastian from Dartford, Kent on Apr 20, 2013

Been using this for 6/7 weeks now and must say that it has definitely helped my weight loss achievements. I was 17.5 stones when I started my exercise and healthy eating program and was 16 stones on my last weigh-in a week ago. I have a shake a day after each 30 min cardio/resistance workout, my daily calorie intake is no more than 1500 Kcal and on some days 1200 kcal. Have now included Maximuscle Thermobol for that extra energy buzz after a long day at work. Great products !!...

Review for Promax Diet by Tombo from Hull on Aug 24, 2012

I decided to attempt to loose wieght when i was at 15 and a half stone, i failed many times staying the same weight then i decided to use suppliments, i chose promax because i friend recommended it, i am now 12 and a half and beggining to see my abs coming though. Its changed me as a person, obviously personal drive was a large part of it but Promax diet gave me the edge at the gym to make it a little bit more fun? BRILLIANT product, taste brilliant with ice cold water, luke warm not so much (strawberry)

Good product

Review for Promax Diet by Tom from Edinburgh on Feb 04, 2013

I am a healthy weight as I do a lot of running anyway and have a good diet, but I started taking this a month ago with breakfast and as a post gym protein source, without adding a lot of extra calories and whilst also getting all the added extras in the power like caffeine and green tea extract. I take one at breakfast alongside a small bowl of muesli with semi-skimmed milk and it keeps me full until around 1pm which is great as before I would find myself snacking around 11. I do feel a bit leaner although weather this is simply from working a bit harder at the gym or using the product I'm not sure. The first tub I bought was chocolate flavour which I mixed with 300ml of water and I thought tasted and mixed fine. However I bought banana flavour second time round had had it for the first time this morning and I think the taste is much better. It is a very subtle banana taste which helps the shake go down really easily. I also add 5g of Maxi Raw creatine charge once a day which I find helps me to do those few extra reps at the gym. This mixes in great and you wouldn't even know it is there. I will definitely be buying this product again, although it is quite expensive I think it is worth it and with the Maxi-reward points and free delivery you are essentially saving 10% on each order.

Taste great

Review for Promax Diet by Anonymous Reviewer on Jan 11, 2013

Its only been a week since I bought it, I took it for breakfast and sometimes post workout. I got the vanilla and really look forward to having it. I found a substitute for skimmed milk, alpro light soya milk. It has less calories compared to skimmed milk and it tastes as great. I'm aiming for weight loss and this shake does help; I don't feel hungry as quickly as before. I will review again if I see any physical results. Cheers
