I am 30 years old, 12 years lifting experience and 10 years as a PT. I have cut around 5x never with this supplement. Previously I have noticed some muscle and strength loss which I thought was inevitable. This time I thought I would try using branched chain amino acids to prevent catabolism of my muscle tissue which studies have claimed it does. I started with about 15g a day, one upon waking, one pre workout and one during workout. Over the next few weeks this did seem to slow or completely prevent muscle breakdown in a calorie deficit. I read more and more studies suggesting that more BCAAs would enhance the muscle preservation and strength so increased my doseage to 40mg for the last few weeks. Well... Some things happened I did not expect. I have more muscle fullness, INCREASED strength and think that I may have actually gained a slight amount of muscle! It also seems to have accelerated my fat loss and my recovery has been immense considering I am a natural trainer, train 6 days a week, in a calorie deficit with about 6.5 hours sleep a night. I have tried fat burners, test boosters, pre workouts blah blah etc etc but this is now my favorite supplement. A must if you are dieting IMO and want to maintain hard earned muscle.Goes Well With:Everything
Theis is a warning. Always go for a flavoured version and mix it with water. The unflavoured is horrific. It's like chewing fistfuls of aspirin. If you add it to a flavoured shake it removes all the original flavour and makes the whole thing really bitter and gag-inducing.
Effectiveness - I've used BCAA's from myprotein in the past and am very happy with the results I get from them. I always put in 110% effort on every workout and as a result have formed an intimate relationship with DOMS. Taking BCAAs lessens the duration and intensity of DOMS by a fair amount, making me able to hit that area again sooner - I train everything twice a week. I can't comment on muscle retention during cutting as I haven't had the need to cut yet. Eat right and you can just keep building lean muscle year round. Flavour - Previously I had some tropical flavour, this time I thought I'd live on the edge a little and ordered Blue Raspberry. Don't get me wrong, its perfectly palatable (if a bit too sweet and not at all raspberry flavoured), I just didn't expect it to be so...blue. I feel like I'm drinking a magic potion from World of Warcraft, and a couple of regulars have very helpfully pointed out that ink is for writing with, not drinking. It does go nicely with the lid of my MP shaker though. There's always a silver lining. Goes Well With:Water, MP blue branding, smurfs.
I ordered the unflavoured variety in the hopes it would allow me flexibility in mixing it with other things and switching up flavours. I was wrong. The unflavoured variety has a very strong distinctive taste. Bitter, salty and chemically. Mix it with water and it'll make you cry and want to remove your tongue and rip your face off as it's so disgusting. Mix it with protein, flavour drops, fruit juice etc and you'll have the same reaction with the added disappointment that you've just wasted your protein/ flavouring/juice. I can't say if it's effective as I couldn't drink a full serving. Anything more than a sip and it induces vomiting as my housemate found out. I mixed it with 30 drops of strawberry flavouring (7-10 is recommended), a scoop of strawberry whey protein and water, no improvement whatsoever, there's no hiding the taste. However the Sour Apple BCAA is quite drinkable. So I've ordered Cherry Limeade in the hopes that'll be good too. Like the sour apple mypre, unflavoured BCAA is gathering dust on my kitchen shelf awaiting the arrival of unwanted visitors as it'll undoubtedly make them leave if served as a drink.Goes Well With:Tongue amputation
Really enjoying my experiments with BCAA's - seems to be providing exactly the boost I needed for quicker recovery and preservation of muscle mass whilst dropping calories. As a girl I'm not looking to get super swole, just to tone up, lean up and bump up my muscle size without getting bulky. This product has definitely helped me to train harder and longer. I'm seeing really impressive results and increased capacity on heavy weights and reps with a significant reduction in BF% and better definition. I have watermelon flavour which is good but pretty sweet. Mixes relatively easily but needs a lot of shaking.
This BCAA product is effective, the flavoured version is always much more palatble and easier to mix than unflavoured. However I just purchased watermelon flavour and it is so sickly sweet I would never buy that flavour again. I previously had 'berry blast' flavour and I would definitely recommend that one. I don't understand why My Protein uses all these hideous additives and colourings to make the drink a synthetic 'watermelon' colour. I would much prefer to have a product with the least amount of additives possible especially one for a BCAA - I don't choose to drink it based on how appealing the colour of my drink is.Goes Well With:water
I always lose muscle with running or cardio but since I have taken this supplement it has solved this issue. I've noticed that I keep my muscle after long runs and my body fat has dropped. It works really well with intermittent fasting and lean diets.
It's tastes like licking Hitler's armpit, this is the taste of pure evil!!! I wish I'd listened to the other reviews. It's a real struggle to take because it's like drinking battery acid. However the service I received was absolutely brilliant as always. The price is brilliant value and it arrived quickly. I can't really complain because I was foolish not to listen to the other reviews. Goes Well With:The sweat of satan.
I have had this in 'berry blast' flavour, which is quite nice. I then decided to re-order some in a new flavour 'cherry limeade' - don't. This is awful. The taste is hideous and it leaves a powdery effect in your mouth. Learnt my lesson: stick to what you know! Also, tip of anyone with IBS, this isn't the best product for our stomachs and I've since started to take BCAAs in tablet form due to the amount of sweeteners in this and have found this has helped me a lot.
Well I am 37 (getting on) and been trying to be a muscle god for over 20 years failing miserable lol. My main issues have been recovery and fatigue. I have nearly finished my first pack and well I have seen some amazing results. Recovery for is now minor issues as I have been taking this supplement before workout , after and just before sleep. The first set with these amino acids actually gave me a ridiculous buzz (dont know why) then I notice fatigue was no near what I had prevously felt. As alway got a cold and was off for about 8 days. On coming back as always I would have ridiculous chest pains on recovery and again these were practically non existent with branched chain amino acids. Again I had an insane buzz on starting training after drinking the supplement. Th buzz could be a placebo effect but I really do think that My body has probably always needed a boost. Loving training again and would reccomend adding BCAA to your diet even if you a 2 to 3 times gym goer , i am now able to go 6 days a week with no issues on recovery. I am taking IMPACT WHEY Protein Isolate as well twice a day while dieting. ******* The key to mixibility is put in a shaker with around 200 -300 ml shake well, let stand for 2 mins and cloudyness goes and it blends with any liquid.Goes Well With:Whey Impact Isolate, Water , dilute Ribena ( or any other berry cordial :)
I was quite reluctant on taking BCAA because reviews I saw all around the interwebs said it tastes like [insert bad word here]. To my surprise, it tasted good - kinda like the blackcurrant squash given to patients at hospital lol (Berry Blast). I found it gave me the much-needed energy boost at the gym to push myself to do those extra reps. It's the first BCAA I've tried ever, so I don't really have a brand comparison. I usually take about 3g-5g before I hit the weights in about 350ml of water. It mixes very well after about 15sec of shaking.Goes Well With:Water
I have trained over a long time and trained others and I have always been natural, you guys know what I mean by that. I've taken proteins and vits and eaten quite a good amount of food and that's it. I reached a good size with great strength & power overall and good fitness and flexibility. For a long while I was using protein powder for before and after training, which is good but not as good as BCAA's in my experience. Taste isn't great but I only use it in it's raw form same as my protein powder. When I started taking BCAA's I definitely saw and felt a difference in my muscle quality as time went on. I swear by BCAA's for helping prevent muscle loss if you train hard and for recovery after training. I can't say I've used it whilst training but 5g + for before training and 5g+ after training depending on your muscle size and needs. Well, this is the amounts I used with good effect. I never used BCAA's alone always with some dextrose or similar, these days I use a teaspoon of Pure Honey and Raw Organic Cacoa. NATURAL IS ALWAYS BEST. Unless your a pro and earning of course. lol. If taste concerns you too much and mixing use a capping machine to make your own caps. Had to do this before when I was taking Glucosamine powder it tasted really bad. Also a lot cheaper doing it yourself with any tablet form.
I purchased the unflavoured version as i'm not too fond of the idea of consuming artificial sweeteners too often unless it's Stevia. I noticed that the flavours available were all strong sour citrus flavours, which i thought was interesting. Of course the logic behind this became all too clear once I had experienced the pleasure of the scent and taste of the unflavoured version. The scent can only be described as beef monster munch soaked in feline urine. Mercifully, the taste is far less exotic and is simply extremely bitter. Which of course explains the aforementioned citrus flavoured alternatives. Gods be praised, as the taste can be masked by just a small amount of orange juice. However, any attempts to hide this foul beast with water or milk will prove futile. As for the effectiveness, I have been consuming this for a few weeks and it dawned on me the other day that I have not been feeling anywhere near as achey after my workouts. I feel like I have been recovering faster too. At first i thought i may have been slacking but the truth is i have been working out harder than ever. Seems like this beast may be beautiful on the inside after all. Perhaps I will get a flavoured version next time. Goes Well With:Orange juice
TRIED A SMALL BAG OF THIS IN BLUE RASBERRY TO SEE IF ITS ANY DIFFERENT TO TAKING THE "HUGE" BCAA TABLETS. WELL I WILL START WITH THE FLAVOUR BLUE RASBERRY IS VERY SWEET BUT TASTES AMAZING LIKE BUBBLEGUM PANDA POPS I DRANK AS A CHILD MMMMM, AFTER MY FIRST TASTE I WENT AND BROUGHT 2X 1 KG BAGS OF THIS STUFF! HAVE NOW BEEN USING THIS FOR A COUPLE OF WEEKS HAVING 2 DRINKS A DAY SIPPING ONE WHILST WEIGHT TRAINING AND MIXING WITH 500-600ML WATER, I FIND THIS IS 100X BETTER THAN TAKING BCAA TABLETS, NO SORENESS WHILST TRAINING AND NO SORENESS AFTER TRAINING AT ALL WHICH MEANS I CAN TRAIN CONFIDENTLY EVERY DAY WITHOUT WORRY OF ACHES AND PAINS! WOULD RECCOMEND THIS 100% TO ANY SERIOUS GYM GOER CAN NOT COMMENT ON OTHER FLAVOURS BUT THE BLUE RASBERRY IS 10/10 FOR ME THANKS MY PROTEINGoes Well With:WATER 500-600ML HARD TRAINING
Even after reading the reviews of the unflavoured version, I thought I'd give it a go. Really curious about what BCAA's will do for me, short term the effects seem to be pretty good; woke up wondering if I'd really worked that hard yesterday, because I wasn't that sore. Looking at my notes though, I would normally have been in pain. Sample of 1, but still, promising. Now, on the flavour. I absolutely can't stomach sucralose, so flavours weren't an option. It was unflavoured or nothing. It's not great. It's kind of gross actually. But the smell is worse than the flavour, so having it through a straw from a shaker helps a lot (Not something I'd want to be seen doing in the gym though, so having it before workouts rather than during) A splash of a tart fruit juice helps, a little. If you want to have something that you can take swigs of during a work-out, and you have any functioning taste buds, I'd say the unflavoured one is not your best option. But if you want bcaa without additives and you're happy to down 200 ml not great tasting liquid before or after a workout, then this is absolutely doable. Goes Well With:a straw, a pinched nose and the need to avoid additives
Has this product enhanced my gym performance? Does this product taste incredible? Does this product make me look like I know exactly what I'm doing in the gym when I shake my BCAAs into my water?! Yes, yes and absolutely yes. Love this product - I always get the Peach Mango flavour because it tastes like delicious juice. Noticed an increase in performance and decrease in fatigue when sippin' on my BCAAs during a heavy workout so I highly recommend these. Summer bod here I come. Goes Well With:Just water.
Great product and can see and feel the effectiveness however unflavored is tastes horrible and struggle to finish it all as i cannot bare the taste, recommend to get a flavor!!
I've been using this no fuss, to the point powdered form for a couple of years now. I don't see the point in all those flavoured products or having it in capsules, it is what it is, as powder, shake it with some water and drink it.... I recommend this to anyone. I find this product especially useful as I don't eat meat, so despite all the careful attention to my nutrition it is still hard to hit all my needs in terms of amino intake.
Sour apple flavour is not as sour as i had hope, it is far to sweet, almost slickly. the apple flavour is there but its meant to be sour apple, that makes your lips smack and pucker, not apple so sweet you can barely drink it. please make it more sour/tarte.
This powder is extremely effective at what it is designed to do, and really helps me to maintain my muscle mass during cutting periods. Having recently just completed a cut, coming down from around 89KG - to 81KG, Branched Chain Amino Acids really helped me to maintain my muscle size, density and strength. Even managed to squeeze more reps out on the 50KG dumbbells! Yes, a lot of my weight was probably water retention, but I lost that and maintained easily with this product. Consuming one serving as soon as I wake up, one before/during my workout, one serving after and one before bed with Casein I find this really aids my recovery. I opted for the unflavoured version as being a student, every saving of money helps and the taste shouldn't bother you, just get it down and quit whinging!
