Gaspari Size-On Maximum Performance is designed as an intra-workout carb/protein/amino complex with a creatine blend. A big thanks to Cray and Cryo for turning me on to this shizzle. That said, let’s get into the review..

----- Ingredients 7.5/10 -----
I’m not going to post the whole profile as it’s rather large and you can easily look it up. This is a 66g/180 calorie per serving hybrid complex carb in a prop blend along with whey hydrolysate, creatine, aminos, etc. Ingredients that stand out (for me) are pterostilbene - an insulin secratogue, whey hydro for di and tri peptides, 5g of l-leucine, sustamine (l-alanyl-l-glutamine), glycerol phosphates and the LOLA . Overall, a well thought out mix of growth and recovery triggers. I seriously just wish it wasn’t in a prop blend. I also personally don’t feel the creatine blend is much of a value add for me but for someone who isn’t taking creatine elsewhere then it’s not a bad addition since it does contain Creapure as the primary creatine. In any case, I’m deducting 1 point since there’s no way of telling how much of any of these ingredients we are actually getting.

-----Taste & Mixability 7/10 ------
Both taste and mixability are, at best, acceptable. It is not the easiest powder to get to mix, and it tends to foam, but if you put it in a shaker with adequate water it will eventually dissolve. I use the grape cooler and it was on the sweeter side unlike some other grape flavors that tend to be more tart. When using it an an intra, I just used a bit more water to mellow out the sweetness. It also takes a bit to get used to the smell. But all these things are relatively minor in my personal rating system; what really matters is effectiveness.

----- Effectiveness 9/10 -----
You can be as critical as you like about the clinical effectiveness of some of the ingredients but one thing that Size-On does deliver on is performance. Given the ingredient mix, its not hard to see why this gets tagged as a bulking agent - 180 calories designed primarily to illicit an insulin spike. I do know one thing, if you want to build muscle and strength then you cannot skip the carbs. We all focus on protein and are willing to spend enormous amounts of money on whey products or so called “muscle builders” but I had no idea how much I was hampering my progress until I started adding serious carbs into my training nutrition.

And Size-On can be used post workout. I have switched from using this as an intra to using it post workout and the results have been great. I guess it all depends on preworkout nutrition and workout style but for me it’s more effective post workout and I just cut the carbs elsewhere during the day.

Recovery with Size-On was much better than anything I’d experienced with other recovery supplements such as adding l-glutamine to my protein shake or mega dosing bcaa’s.

Strength and energy increased, primarily due to the addition of a quality carb source to my training nutrition (and increased greater than what I saw with carb sources like maltodextrin). In the past I have been very frustrated with loss of strength while trying to cut, but with Size-On, I get a great carb hybrid which is allowing me to moderately reduce bf while still add muscle and increase strength.

----- Value 6/10 -----
I got like 20 of the smaller tubs during an insane deal from Allstarhealth, so I’m rating this using the normal retail price which comes in just under $2.00/serving. That is one expensive carb when you compare it to oats or maltodextrin. However, I do think that it is just effective being taken in a half dose post workout and for that method, it comes in at just under $1.00 per serving and definitely would bump the value up a point to a 7, or maybe a 7.5. Of course, you have to compare this to whole food carb sources and as such, it’s always going to be a more “luxury” type purchase.

-----Overall 8/10 -----
If you are looking for something to help trigger some real success when combined with serious lifting, and willing to spend a bit more money, then I think this is a fantastic product to try out. If you are a casual lifter then I think you’re money is probably better spent elsewhere. I particularly like that fact that it is versatile enough to be either an intra or post workout carb source. I also love the fact that you don’t have to use a full scoop and that greatly improves the value. All in all, this is now an addition to my “staples”.

I've taken this supplement for 2 cycles: each cycle consisting of 4 tubs (15 weeks each). First off, tastes amazing - looked forward to taking every day... Artic Lemon especially - tastes like lemon meringue pie... :) Didn't mind sipping through it while I worked out.

I've been training over 15 years so I didn't anything too much from it. Slightly increased my strength but nothing dramatic (based on my years of gym experience). It did increase my weight by around 10 pounds after a month. No this was not new muscle, but just the water being retained inside the muscle cells.

Compared to the new Maximum Performance stuff (which has Isolate peptides and costs a lot more), I just added 10-15 grams of Leucine powder to my shaker bottle when taking. In my opinion this created an even more potent formula and the carbs/sugars in the Size On helped Drive the amino acid into my muscles (along with the creatine) while I lifted. For $30/kg for Leucine (lasts months) well worth it.

Overall a good product. It's still just creatine so don't expect ridiculous results. Keep in mind my training background I didn't have much room for new muscle growth as I'm near my genetic limit.

If you're training well, eating 4+ solid meals each day (plus 2 shakes/day) then this would be the next supplement I'd add to your program. Again, add 10-15 grams of Leucine (or WPI) to the shake to reap more benefits.

Bought the Maximum Perfomance blend, and worked well enough. Far too expensive though, came out to almost $100 cuz California loves high sales taxes. Love how one tub works out to a 1 month cycle, which is a problem for other powders. Tasted great, but you kinda hafta miz it with at least 30oz of water. Anything less and it will come out somewhat bitter, and you might have overflow problems in your shaker cups. After you shake it wait a good while before you take you first drink cuz it gets a crazy big head(foam), and opening it prematurely will be rather messy. I take it intra-workout(while you workout), and it works good in that respect. I got a little bloated at times, but nothing a good hearty belch won't fix. The scoops though are huge, which was just a little odd to me. I got good size gains from this, but no real strength gains. Weight started to increase steadily, going up a good pound or so about every week or so. Don't know if it was just me or the SizeOn, but I would get mean munchies in the evening. The weight started to level off towards the end, and I went from 205lbs to 209.5lbs. It's a good product, but there are better products for less money.

I had always looked at this product for years whenever I was looking for a new creatine and only recently had I just finished my 1st tub of it, and boy did it deliver.

Effectiveness 9/10- The name for this product is perfect because you literally put size on while on it. I was using this during my workouts and took Carnivor as a post workout protein for the past month and a half and off that stack I've gained I'd say 7-8 pounds. Also recovery is good with this I rarely felt sore while drinking it

Taste/mixability 8/10- I had fruit punch it was a little on the sweet side but outside that it was very good had no real issues with it. Mixed very easily to.

Value 9/10- At the place I go to a tub of creatine or protein is anywhere from $35 to $40 and I think for the supplements that deliver like this one thats a fair price.

Overall 9/10- With how well this product worked for me I am actually mad at myself that I held off this product for at least 3 or 4 years. Outside of N.O synthesis, which is a post workout creatine I took in high school, this stuff is the best creatine I've taken. Does as advertised in my opinion

Hey I finished up my 3rd tub of this and I figured i would finally post a review about it. I just want to start out by saying this is a great product that i recommend to anyone who is looking to safely but a little size on. I've always been fond of Gaspari products I've really had no negatives to say about the products.

First off I see a lot of people saying that this product is a little pricey. I do agree that this is a little pricey but when you figure in the results you get and compare it to what you would spend on a lesser product and HOPE to get the same results i personally do not mind dropping an extra 20 bucks to get a quality supplement. With that being said, the larger tub i got for 46.99 with a discount dropping it to 40.00$ This lasted me a month and two days. I think that this is a great price for that.
Price: 8/10

Result wise, i was excited beyond belief. I put on about 5lbs with this that i kept. I would say i put on around 8lbs 3 of which fell off. I intook roughly 1.5 gallons of water while on this so i attribute the 3 lost pounds to myself. I like to be hydrated what can i say. This product also helped me get my weights up. My strength was solid throughout. My bench went from about 5 reps of 275 to about 4 reps of 285 while i was on this. I dont exactly attribute that directly to the supplement but it sure as heck didnt hurt.
Results: 9/10

I stacked this supplement with Gaspari's Myofusion peanut butter chocolate protein. This to me was an easy choice because if you bought the size on you got the protein for 10 bucks so it was an easy choice.

Taste: This is where this product sets head and shoulders above others. Now i will say that i think i got the best taste. I took Grape. The best comparison i can give is that it was identical to the blue tootsie pops. I mean serious i would sip on this if they sold that taste as a water flavorer. It was just a great easy taste to put down. My buddy however got the fruit punch and absolutely Hated the taste. He couldnt even finish it he had to get another tub of different flavor. The grape however, gets a 10+
Taste 10/10

Would i take this again?
Absolutely i would and will. I'm deciding i need to put on more size so I am preparing to start my first PH. But this product is something that I will get on after that cycle. Not a doubt in my mind i will jump all over this. And i advise you too as well.

This is my first review so i hope that y'all find this helpful any questions of something maybe i didnt cover or y'all need answered i will be glad to answer.

To start I want to say I love Gaspari nutrition supplements. They usually deliver in quality and I think its a great company overall.

Effectiveness 9/10
Size on is awesome in effectiveness. It is loaded with carbohydrates to keep glycogen stores full while you are working out, 6 grams of bcaa and over 6 grams of creatine. The blueberry flavor tastes great and is enjoyable to sip on while lifting

Value 8/10
40 bucks for a month of servings really isn't great at all but its a good product so I had to try

Overall 8/10
Pretty good product. Lots of creatine, does make me bloated a little. Its got a lot of leucine which is a bonus and is great for adding endurance and recovery to workouts

Size on is dope. You take it during your workouts for better recovery and performance.

Ingredients: Full of creatine monohydrate, carbohydrates, and bcaa. Each scoop has like 5 grams of bcaa which is very beneficiall

Overall 9/10
Very effective but also pricey. A bottle of 30 servings is 45 bucks

Excellent product.

Lets start with sides and/or cons.

This stuff gets you bloated. Creapure is simply monohydrate which will get you bloated. This is also a very pricey product but it does in defense have a heavy profile.

Size on is to be taken intra workout. Plenty of carbs for energy, loaded with bcaa especially leucine which is a huge bonus, along with creatine and some b vitamins.

I without a doubt noticed strength gains while stacking size on intra workout. This stuff was like 45 bucks for a month of scoops which is pretty pricey but do able.

Overall 9/10
Great creatine/intrafuel product I recommend!

SizeOn is one of those products that you don't realize how good it is until its gone.
When I first started using Sizeon, I didn't notice a difference. The only major difference I saw was my size and weight. I gained a solid Lb a week on this with a good DIET. I also appeared to gain some decent muscle after using two tubs back to back.

However, I soon realized how much SizeOn really did do once it was gone. After it was gone I noticed my energy during workouts was not as high. My muscles fatigued quicker and I needed more rest between sets.
My strength gains slowed down as well.
As I was using this during a bulk, my weight gains slowed down as well even though my diet stayed the same.

Its an Overall pretty good product, I just wish it wasn't as expensive. If you buy the stuff, please eat right and drink enough water!! I've used 3 tubs of SizeOn, the first tub went to waste because I was an idiot and did not eat nearly enough. If you eat right and train hard, this SUPPLEMENT will do exactly what it claims to do. Just look for it on sale and I'd recommend it...

Let me start by saying Gaspari is a great brand and most of there products are of good quality.
I don't respond particularly well to creatine for the most part, but this one was the most effective for me. I had some muscle growth, improved endurance, and didn't see a lot of bloating.
The biggest plus for me on this product is the taste, I understand that no one is gonna buy a product for it's taste but dang this stuff tastes GREAT!
And of course, like almost everyone has said, it's only true con is it's price, but hey you get what you pay for and it's worth it.
I would definitely recommend this product to anyone who wants to see good improvements in a short amount of time! (Just don't expect the results to be on par with anything like a test booster or roids.)
