LA Muscle Tubs
In line with LA Muscle’s Green Policy and reducing carbon footprint, LA Muscle is using a “ONE SIZE” tub for most supplements. This is to reduce the use of plastic tubs by having tens of different sizes for various products and having to over-manufacture plastics. As a result, you may find that in many LA Muscle supplements, the tub is much bigger than the total size of all pills. You are still getting the exact number of pills/capsules/powder you have paid for, however there will be extra space at the top, giving the impression to some people that the tub is not full. This is solely because of our commitment to reducing the need for making extra plastic tubs. LA Muscle does not use cotton wool to fill up the extra space because cotton wool can attract microbes. Your safety AND the protection of the planet are big parts of the LA Muscle ethos.

Asked by Abdallah Husain on 5th August 2016

Hi Abdallah, it contains simple carbs.

I saw that taking Fat Stripper Intense alongside this is a good way of minimising fat increases from the mass gainer. I was wondering whether the gainer + Six Pack Pill Extreme, Fat Stripper Intense, and Norateen Extreme together would be good?
Asked by Dominic Weir on 27th July 2016

Hi Dominic, yes you could take all of those products in that combination.

Hi LA.....I m looking at gaining muscle mass and I m struggling with stomach fat.......will mass gainer make me fatter ??
Asked by J Evans on 3rd April 2016

Hi, when using mass gainers usually some size will be added which includes some fat but you can take a fat burner alongside it to keep the fat increase minimal. For a lean mass bulk you can go for Complete.

Can this suitable for skinny guys that find it difficult to gain mass??
Asked by ryan Milligan on 27th February 2016

Hi Ryan, yes this would be very beneficial and will help add mass.

Hello Do you take this everyday or just on training days? Thanks
Asked by Khian Mility on 19th October 2015

Hi Khian, you would need to take this every day to get the required calories to add size.

Hi Liam, yes you can.

Hi, Ive been using mass gainer for a while when i first bought it you used to get a smaller size scoop but now you get a shovel like scoop. because your supposed to have two scoops to get 1200 calories, which scoop am i supposed to use? Thanks
Asked by Phillip Doyle on 21st November 2014

Hi Phillip, the mass gainer has the larger scoop so you will need 2 scoops for one serving.

i bought some Mass Gainer and it says take 2 scoops i tryed it a couple of times and it gave me the runs can itake 2 of the small scoops and if yes will i need to take it more often to make up the calories
Asked by Richard badloe on 18th November 2014

Hi Richard, the smaller scoop is not recommended for that product as you won't get the required calories. You can halve the serving amount to 1 scoop (150g) and have it with around 400-500ml of water. If you have 2 servings like this per day then you will get the recommended calories.

Hi James, yes as it's similar to a protein powder it can be taken all year round if you wish to do so.

300 gram does not fit into a la shaker. It also does not mix welll???????
Asked by JANET MCKINNON on 1st May 2014


You should blend the mixture in a blender as this will ensure it will blend effectively. After it has blended wait for around 30 seconds and pour out the drink into you shaker. You can also add some ice to make it more refreshing. This should do the trick.

Hello can I combine LA Whey Mass Gainer with eclipse, nuclear creatina and norateen extreme! I am bit concerned about the amount of creatine that the combination will add to my body! I'm using the first month of nuclear creatine!
Asked by Artur Santos on 13th April 2014

Hi Artur, yes you can use all of these products together if you wish to. The amount of creatine absorbed per day from the servings is completely safe. Combined with a strict diet and intensive training program you should see great results in no time.

do i still need 2 scoops a day of explosive creatine if i take it alongside this product as i contains creatine aswell. thanks
Asked by John Evans on 30th March 2014

Hi John, yes we would recommend you continue to take the Explosive Creatine as a pre-workout.

Does it contain any creatine?
Asked by Asad Ahmed on 27th March 2014

Hi Asad. Yes each serving contains 600mg of Creatine Monohydrate.

I would like to know why do you have to so much water with only two scoops?
Asked by Asad Ahmed on 26th March 2014

Hi Asad, the 2 scoops amounts to 300g so 700ml of water is required to make the texture smooth to drink.

I'm interested in finding out about how much of the carbs in this is made up of sugar, if any?
Asked by Liam Gordon on 21st March 2014

Hi Liam, our products do not contain sugar. The sugar content of the carbs is made up of Steviol glycosides, which are a natural form of sweetener and are responsible for the sweet taste of the leaves of the stevia plant.

Hi, I both eclipse and norateen extreme! Regarding protein which one should I go for? La whey gold or La whey mass gainer? My goal is to get big! And please, how to take this combination in and out of the gym! Thanks
Asked by Artur Santos on 11th March 2014

Hi Artur, LA Mass Gainer will help you increase your overall size however if you are looking for an increase in size of purely lean muscle mass then we would recommend LA Whey Gold. Either of these can be taken with Norateen Extreme for optimum results. Please send an email to for more information on the combination of these products.

Hi, I reguraly buy LA Whey, however I am trying to bulk up does the mass gainer contain lactose? as I am lactose intolerant and I find the LA whey being lactose free is perfect for me. Thanks, Michael
Asked by Michael Waggett on 9th March 2014

Hi Michael, the LA Whey Mass Gainer, similar to LA Whey, does contain milk however it has been triple filtered to remove all impurities and allergens. If you have been taking LA Whey with no issues then you should be fine with the Mass Gainer.

Asked by Christopher Dawson on 6th March 2014

Hi Christopher, the Mass Gainer has a smooth soft taste and great mixability. It has been developed to be a very effective mass gaining formula and will not cause bloating.

How long does this last (how many servings)
Asked by Graeme Simpson on 5th March 2014

Hi Graeme, The Mass Gainer has 12 servings per tub, which is 300g (2 scoops) per serving. Depending on your calorie requirements, you can half this and use one scoop per serving, which would be 150g and would provide 24 servings.

could you confirm how much soya this has compared to bronze way as the soya was overpowering for me, if it tastes more like the trastional whey protien you sell then i would invest, do you have a money back scheme as its new and isnt tasted/tested yet?
Asked by Tom Smith on 5th March 2014
Hi Tom, The La Whey Bronze has the most soy protein. LA Whey Bronze has both Soy Protein Concentrate and Soy Protein Isolate in the protein blend, whereas the Mass Gainer has no Soy Protein Concentrate / Soy Protein Isolate but only Soy Lecithin that helps to make the Whey Protein Concentrate disperse better.

hello thanks for that, when you say smooth, do you mean its more like the traditional gold whey you provide as the taste of that i like but if its like bronze whey this would be an issue, just want to know as i will pre order if taste is confirmed.
Asked by Tom Smith on 5th March 2014

Hi Tom, the mass gainer tastes smooth as it has great mixability and a nice taste to it. All of our powders will vary slightly due to the active ingredients however you should be satisfied with the product.

what does la whey mass gainer 3.6kg do from la whey 2.2kg.
Asked by Thomas Finnerty on 5th March 2014

Hi Thomas, Mass gainers contain a significantly larger amount of calories than regular whey protein. Mass gainers are geared more-so towards those who are looking for a quick/convenient shake for a type of meal replacement. The calorie and macro-nutrient content (protein, carbs and fats) make it suitable for those who are looking to add more calories to their diet. Whey protein can be taken any time to increase your protein intake.

Hello, I found the soya intake from bronze whey very over powering, what does the mass gainer taste like as I have noticed it has the same ingredient of soya letchin? Thanks
Asked by Tom Smith on 4th March 2014

Hi Tom, the mass gainer has a nice smooth taste and contains very little soya protein.
