Why buy Reflex Instant Mass Pro 5.4kg?

Instant Mass PRO is not a typical weight gainer, it is an ultra high-quality weight gain product made with a near 50/50 split of protein and carbohydrate.

With 54 grams of Quattro time-release protein per serving this is arguably the highest quality blend found in a weight gainer.

Quattro is unique to Reflex and consists of three different types of whey protein, pure low-temperature ultra-filtered whey protein, hydrolysed whey protein and low-temperature native whey protein isolate; these 3 super proteins are combined with pure low-temperature micellar casein to provide four of the best - Quattro!

    “ The Plus: Good amount of proteins per serving and good carbs. It hasn't yet given me any stomach trouble. Good results so far. Negatives: It might need a blender or some rather vigorous shaking to mix properly. The taste is not that great. ”

    “ Excellent product: The carbs don't all come from sugars like the other crappy cheap gainers out there. Very high protein for a shake, tastes good, didn't mix perfectly but that's not important at all, it's the ingrediants that count. I'm buying this again for sure. ”

    “ Why are you advertising this product as 80 servings?? it states on the front of the product that it only has 40 so your calculations are incorrect too and this is false advertisement! i nearly bought this product thinking i was getting a pretty decent deal only to find out i wasn't. I hope this gets corrected soon and nobody falls for the trap i nearly fell into. ”

    “ I've used several weight gainers over the past years and in my opinion reflex instant mass is by far the best high quality gainer on the market. I can quite happily give it five stars in every aspect. The ingredients are top quality with the most important aspect being the use of oats and barley as its carbohydrate source. I have previously used maltodextrin based gainers previously and have found they have a tendency to put on fat. Since using this I have only seen good quality lean mass gains. Taste is excellent although I can't comment on the strawberry as I've only tried the other flavours (not a strawberry fan). The 5.4kg bag is excellent value. Previous comments regarding lack of scoop and quality of seal have been addressed. There is now a scoop and a durable ziplock style seal which works perfectly. It is clear that reflex is a company that listens to customer feedback and improves on weakpoints which is good to know. All round 5*. James ”

    “ I've even used to USN muscle fuel anabolic as my weight gainer but I thought I'd mix things up and give this a go. I also changed my training program when I received this product to try and put on some good size. First of all, I HATE when companies use bags instead of plastics tubs! Makes scooping it out a lot harder and the re-sealable bag broke within the first few days so that was abit annoying but I have my supplements in a box in my car so it didn't effective me too much. Scoop was included as it should be. Effectiveness was really good, was taking 4 scoops x 2 a day, pre work out (stacked with decabolic creatine) and one post work out. Put on about 1.5kg really quickly, which been a hard gainer is hard enough but this product just helps you push abit further. Good size improvement on my arms and chest which people have commented on but I also think This is down to my new training program which is brilliant. Taste is good, I like the taste! Taste isn't as good as PHD synergy for example but it's bearable and doesn't make me gag like USN muscle fuel anabolic (in chocolate) did! It shouldn't be about taste anyway to be honest, just get it down your throat and train hard but if it tastes good it's always a bonus. Mix ability is fine, I just use a standard shaker with the removable mesh thing! Shake for 20 seconds and it's all mixed in well, hardly any lumps and can drink it with ease. I know most people looking at weight gainers are hard gainers trying to put on size, if so then grab this product because it really has helped me put on size! Definitely recommend, will be buying 2-3 more bags over the next couple of months before a cut prior to winter. ENJOY! ”

    “ I bought 4 x 5.4kg bags. It mixes, tastes and looks great. However compared to other gainers it is a bit on the limp side. I struggled to maintain weight with this, never mind gain. That said, I have used many gainers and this is by no means the worst. But unless you're under 80kg this is not for you. ”

Customer Questions
  • "Hey, is this instant mass as it has a pic of instant whey. Also i have been training for bout 4 1/2 months, and taken a fair few supplements, but now taking Instant mass and pharma whey, and looking to add synegy into the mix, will that combination work? cheers "
  • "How many servings does it contain?"
    Hi Peter You gey 40 servings per bag. Kind regards Danny
  • "Is this Instant mass or whey, would hate to spend £50-60 and get the wrong thing .. Also, it says in the details its 80 servings, yet you say 40, why is this ?"
    Hi Ryan This is the mass.
  • "Do you do the banana flavour in the big bag? If not, is the strawberry flavour palatable?"
    im afraid we do not. the strawberry flavour is very nice. -AC-
  • "How long will a 5.4kg bag of instant mass last? "
    there are 80 serings. if you have 1 per day it will last 80 days, if you have 10 per day it will last 8 days. -AC-
  • "Whats the actual amount of powder for each serving as on the bag it says 136gm!?! and as they dont include a scoop its hard to get it consistant as it says tablespoons"
    each serving should be 136g. it is impossible to get it exactly right without weighing. -AC-
  • "Would this instant mass work well with reflex instant whey if not what weight gainer would?"
    yes. -AC-
  • "I have a rugby trial in 2 months and i need to gain as much weight as possible without losing speed, what would you reccomend i stack together to achieve this?? thankyou !!"
    hi lee, the instant mass is great for lean muscle gain. i recommend stacking it with a creatine monohydrate like reflex creapure to keep your explosive power. Best regards -AC-
  • "How does this product equate to 80 servings when the 2.7 kg version only gives you 20? Thanks Zohran"
    hi zohran. Reflex have put 80 servings instead of 40 as they can advise you can have a serving half the size of a normal serving. they have used this fugure for the number of servings. Best regards -AC-
  • "Hi is there any chance you can get the banana flavour in stock please? otherwise got to order off the reflex website and its alot more expensive. Regards"
    hi daniel. We will add this flavour to the next order we place with them so should have the banana flavour in stock shortly. Best regards -AC-
  • "Are the carbs in this shake fast acting or slow?"
    Hi Sam Some of the Carbs are from sugars, but the majority of them are from maltodexrin and complex carbs. best regards -IE-
  • "Hi, is this supplement better for gaining weight than the usn muscle fuel anabolic? regards"
    hi there-its an excellent product for gaining mass as its got different types of protein and its low gi -however as an all in one the usn has a few extra s in it
  • "I really want to bulk buy this product but need a new shaker. Many products on your site come with one free is there any chance I could have a promotional code for this this product so I could get the shaker with this product? Thanks in advance!"
    HI Sam, If you place your order over the phone I'm sure we can sort something out for you. Kind Regards, Josh
  • "Can you use this one whilst using the reflex instant whey?"
    hi there-yes they are fine to use together although the mass has more carbs and calories in it.
  • "When can i order this product as it is currently out of stock."
    this is due back in within the next week. Best regards
  • "When are you going to have more in stock?"
    hi there dave sorry for the delay-we have now restocked-thanks ian
  • "Is the product suitable for vegetarian? Which product is the best in the market for size and strength which is also suitable for vegetarians?"
    Hi Fahd. Im not sure whether sure whether it is as i have never used it myself, the best thing to do would be to contact reflex and ask them. however this is a very good product for putting on mass. yours in health. Mohammed Giaffar.
  • "Im going to bulk up in 3weeks and was hoping u could tell me if thhis and a slow realing protien such as pepties fusion would be a good stack or would i be better of with one stop extrme and a slow realing protien also could u recomend a weight gainer as im 12.9 and wanna get to 14-15 stone and could i stack this with tauro test"
    Dear Louis, This is a very good weight gainer, as the carbs are derived from oats and barley. In my opinion it is one of the best products out there. I would look at pure protein igf1 or pharma blend by PhD to use as a slow release. Tauro test would stack great with these two products. Dave
  • "Hello, would you please ship this product to israel? thanks"
    Dear gena, We dont ship to isreal unfortunately. Dave
  • "I noticed its changed too native whey,is this more or less effective? also why has the calories and carbs gone down?"
    Dear Jamie, it is even more effective now, the native whey is a brilliant replacement. The kcals and carbs have been cut due to the fact less sweetners and flavourings have been used. It is very pure. Dave
