Summary
Gaspari took Sports Nutrition to the highest level with SizeOn, the original intra-workout creatine drink. As clinical research advances, so does Gaspari Nutrition which is why SizeOn has now evolved into the Ultimate Hybrid Intra-Workout Whey Hydosylate Creatine Formula. SizeOn now uses a high quality whey hydrosylate that contains over 50% di and tripeptides as well as a large array of anabolic promoting ingredients such as a high dose of L-Leucine (5 grams) to allow for unparalleled support in athletic performance, skeletal muscle recovery, explosiveness and most notably, immediate increases in muscle size while you are still training.
Furthermore Gaspari Nutrition researchers have harnessed the power of pterostilbene - our patent pending and brand new insulin secretagogue - picked specifically to work in concert with our universally acclaimed and patent pending Outlast carbohydrate blend. This powerful combination initiates and promotes muscle volumization and anabolism to levels never seen before in a sports nutrition product. To top it off, we also included LOLA, our cutting-edge, ammonia scavenging amino acid salt of L-Ornithine and L-Aspartate to help battle fatigue. The bottom line is that Gaspari Nutrition has once again outdone itself and yet again redefined what an intra-workout supplement should be - a category of product we created years ago!
What is the difference between SizeOn Maximum Performance and SizeOn Pre-Contest?
SizeOn contains the revolutionary Outlast carbohydrate complex for maximal performance in the gym and recovery and it contains pterostilbene - our patent pending, naturally occurring insulin secretagogue - which helps to push those carbohydrates (and amino acids and other nutrients) into skeletal muscle cells to maximize glycogen synthesis, cell volumization and myogenesis. This formula is geared towards an athlete looking to "bulk up as fast as possible." SizeOn Pre-Contest does not contain the Outlast complex nor pterostilbene.
What is the difference between the new version of SizeOn and the original?
The new version of SizeOn contains high amounts of whey protein hydrosylate, leucine, along with more carbohydrates as well as pterostilbene to support insulin levels already within normal range. All in all, it is a much more advanced product based on cutting edge research.
Can SizeOn only be used by bodybuilders or can athletes looking to build muscle mass and enhance their recovery use it as well?
SizeOn can be utilized by anyone wishing to speed their recovery, build muscle mass, and increase performance.

great stuff
Jason Gwyer on 4th September 2010
Tried the old stuff and the new in both grape and lemon, as for taste this intra workout supplement aint gonna win any accolades. BUT for doing exactly what it says on the tin its a five star anabolic revelation. Mental focus, drive and ability to attack the gym are all up in turn the muscle fibres are shredded and quality growth is apparent from day one, just wish they did it in a bigger tub!!
Great product

Q & A
- Q. hi could you take this product twice a day? would i see any extra benefits?
regards - A.
SizeOn is meant to be taken on training days while you train. Mix one scoop in 20-30 ounce cold water and sip throughout your workout.
- Q. im looking to gain weight by packing on the muscle, i currently use maximuscle cyclone before and after training, i was just wondering if it would be ok to use size on whilst im training then take cyclone straight after my workout. Would this be ok? thanks for your time. John
- A.
Yes this would be fine.
- Q. Dear support,
I use support drinks during my weightlifting workout to get enough carbohydrates and keep myself hydrated. I just came to know that Gaspari SizeOn is also used during workout. I am thinking to replace support drinks with “Gaspari Nutrition SizeOn Maximum Performance” supplement. The only issue I am confused with is that it contains curtain, vitamins and other amino acids and I already use other supplements with same ingredients. Will “Gaspari SizeOn” be over dosage then?
I use following supplements daily:
Protein:
Optimum Nutrition Gold Standard 100% Whey (Includes Glutamine and BCAA)
Optimum Nutrition Protein bars (Wholly Oats! Bar, Whey Crisp Bar, Granola Bar)
Creatine:
BSN NO-Xplode
BSN CellMass
Multivitamins:
AST Multi-Pro 32x
Greens (Contains over 4000 mg of Barley Juice Powder per serving and it includs vitamins, minerals, anti-oxidants, amino acids and enzymes)
Please advise, is it ok to add ” Gaspari SizeOn” on top of above mentioned supplements? - A.
You'd be fine as the vitamins are minerals are in moderate doses which with your intense training you will be exposing yourself to free radicals which is where these vitamins, anti-oxidant mixes come into play and help you out. Size on is brilliant intra-workout and would be considerably better than a support drink be that Lucozade or powerade.
- Q. i use myofusion at the moment, if i was to buy size on max, when should i take myofusion and when should i use the size on, its it a good idea to take the size on during training and then still take the myofusion straight after?
- A.
SizeOn is to be started right as you start training but the ingredients lend themselves to being an effective pre-workout product also, so you could start it several minutes before you train. Sip it slowly, don't down it.
Yes, still take your Myofusion straight after training. Also, if you are trying to make gains, definitely have some carbs with or just after the Myofusion. - Q. Hello, I am currently on Bio Rhythim Kre Alkalyn, I am about to purchase real mass for my weight gianer by gaspari, wud there be any point in purshaing gaspari size on ? Some of the review say it is bascially a creatine drink? as i am currnetly more than happy on kre alklayn and do not wish to change. so would there be no point in buying the size on ?
- A.
Real Mass is a great weight gainer and will ensure you get the calories you need to grow. Kre-Alkalyn is a fairly mild creatine product, so adding in the SizeOn for during training will likely enhance you results. It contains a large amount of leucine, hydrolysed whey and other very effective ingredients for maximizing recovery and muscle mass, so it's not just a creatine product (the old version was basically a creatine product so maybe that's where the confusion lies).
- Q. Hi,
I am about to add "Gaspari Nutrition SizeOn Maximum Performance"in my daily routine and wondering if you can guide me if its ingredient meets my requirement.
If the product is suitable for vegetarians than its ok for me but if it is not then I want to confirm followings.
Basically I am looking for a “Hillal” product. In case if you are not familiar with term “Hillal” then here is the definition.
If it passes the below mentioned requirements then I will consider it “Hillal” and it will be ok for me.
Product do not include Swine/pork and its by-products
* Animals improperly slaughtered or dead before slaughtering
* Animals killed in the name of anyone other than (God)
* Alcohol and intoxicants
* Carnivorous animals, birds of prey and land animals without external ears
* Blood and blood by-products
* Foods contaminated with any of the above products - A.
This is Hallil by your definition
- Q. Hi,
Is it safe to take Size On along with Muscle Fuel Anabolic. I have previously used both products but on separate occasions and wondered if I was ok to combine the two.
Thanks - A.
Yes, it's fine to take both together.
- Q. Can you tell me when the grape or berry flavours will be in stock please? Thanks
- A.
It's very difficult to say. The importer has been a bit inconsistent lately but should be soon.
- Q. Does this product contain creatine or will i need to take creatine alongside this? Thanks
- A.
SizeOn does contain creatine but you have to take it every day (not just after workouts) to get the effects. You could take another type of creatine product on "off" days.
- Q. if i train 3 times in a week,sometimes 4 times ,should i take size on only in the training days or take one servingit every day?thx
- A.
Taking it on non-training days would help for sure. It would give you more muscle-building ingredients more often!
