PTfootball54's SizeOn Maximum Performance Review

Overall: 8 | Effectiveness: 8 | Value: 6

After trying the Original SizeOn a couple years back, i finally decided to try SizeOn Max, and i have to say i am impressed.

Price/value: When i first looked at this, the first thing i saw was the hefty price tag. I bought this at GNC when it was on sale and it was still 40 dollars, for 24 servings...

Gaspari Size on. I'm still not 100 percent sure how I feel about this product. I bought it extremely cheap from lockout back in September and have used 5 of the 5 serving tubs. Which equates to a little over a full container. Needless to say I was not overly impressed with Size on. On to the review.

Ok.. so I got this as a deal with my superpump 250. Really good product i think. Surprisingly I have not seen good reviews on this. I honestly think it is because of how people were taking it. It worked really good for me and I think it should def be tried.

I'll break this up into energy, strength,...

I'm sure we all remember when "power" let us all know of a clearance on SizeOn. Thank God for allstarhealth! Anyway I picked up 8 of those small tubs(almost 2 tubs worth) and finally finished them all. I have some extra time on my hands and decided to write up a review.

SizeOn is Gaspari's intra...

When I first got put on to "size on" through a couple guys at the gym who spoke highly of it, I did not know whether to get the max performance or the pre contest. I just know that these 2 guys loved the stuff and said it tasted like kool aid. SOLD.

So I went with "max performance". I was already...

Mediocre Intra, but a good Creatine

Overall: 7 | Effectiveness: 7 | Value: 7

At first glimpse, SizeOn looks to be a very promising supplement: Creatine, BCAAs, Carbs, Protein. Throughout my run with it however, I didn't find myself particularly impressed or "wowed" by SizeOn.

this product is PERFECT for a winter bulk. i used an entire tub of it while i was doing more heavy lifting, with drop sets to volume. i was not doing any cardio, and my diet is spot on with bulking. i put on probably 5 lbs in a month, but my strength and fullness were the most noticeable. i was able...

Rush94's SizeOn Maximum Performance Review

Overall: 8 | Effectiveness: 8 | Value: 7

I went into taking the product with very low expectations. A tub was given to me by a friend who did not like it, so right off the bat I wasn't very excited about it. But I figured, why let it go to waste? The least I could do was try it out and share the results with all of you fine people.

I have...

I had been wanting to try a intra for awhile
due to the fact that I get very hungry during
some of my workouts which can last up to 5
hours. When this happens I would eat chocolate
& sometimes bananas. This worked for me but I
wanted something to better feed my muscles so
I chose SizeOn Max. for...
