Ingredients Label
Active Ingredients
Insutropin Matrix
This matrix is a mixture of carbohydrates that are both fast and slow-releasing.
This provides you with a steady stream of energy throughout your workout.
Whey Protein Hydrosylate
Whey protein hydrosylate is a quickly-absorbed form of whey – a milk protein.
It can significantly increase muscle growth and repair (1).
BCAAs
“BCAAs” is the group term for the amino acids leucine, isoleucine, and valine.
Taking them can reduce the production of stress hormones during exercise, and help you to recover faster (2).
L-Ornithine-L-Aspartate
L-ornithine-L-aspartate is a combined version of two amino acids.
It has shown promise in reducing fatigue in patients with liver damage (3).
Ornithine on its own has also demonstrated great fatigue-reduction effects in healthy people (4).
Creatine
Creatine is a strength-boosting compound that’s found in small amounts in animal food products (5).
The best-researched form is monohydrate, but other forms may have better absorption and effects.
It needs to be taken daily, at a dose of about 3-5g.
Who Takes It?
Athletes wanting to improve their workout quality and reduce muscle breakdown will benefit from Size-On.
How to Take
Mix 1 scoop (66g) with 600-700mL water, and consume during your workout.
Side Effects
Creatine can cause stomach cramps if taken without sufficient water. It can also cause a slight increase in water weight.
Pros
- Creatine and BCAAs in one product
- Reduces fatigue levels
- Great-tasting flavouring options.
Cons
- Proprietary blend doesn’t tell us whether or not it’s an effective dose of creatine.
Conclusion
SizeOn serves a bunch of functions to improve the quality of your workouts, as well as muscle growth and repair.
Unfortunately it’s a proprietary blend, which doesn’t tell us if effective doses are used.
The flavours are great, and it’s enjoyable to sip on while working out.
