Gaspari SizeOn Intra-Workout

Gaspari SizeOn — The Original King of Creatines

SizeOn is one of the most iconic intra-workout formulas in bodybuilding — the original award-winning creatine product, now evolved into a complete hybrid formula combining high-quality whey protein hydrolysate (clinically proven to absorb faster than free-form aminos), a premium multi-form creatine blend and an amino acid matrix. It's what serious trainers have been using to fuel sessions and accelerate recovery since the Gaspari golden era. 24 serves in Wild Berry Punch, Grape Cooler, Orange Cooler and Lemon Ice, in stock at TopDog Nutrition.

Key Benefits

• Whey hydrolysate — faster absorption than free-form amino acids for rapid intra-workout delivery.
• Premium multi-form creatine blend — covering multiple creatine pathways for strength, power and cell volumisation.
• Amino acid matrix — complete amino support for endurance and recovery during the session.
• Intra-workout timing — designed to be sipped through training for continuous fuelling.

Where It Fits

SizeOn replaces standalone creatine, BCAAs and intra-workout aminos with one product — sip it through your session and follow with a protein shake after. If you want a pure creatine option instead, browse the creatine range.

Directions

Mix one serve with 400–600ml of cold water and sip throughout your training session. For best results, use consistently on both training and rest days — the creatine component works through saturation, not single-dose timing.

Frequently Asked Questions

Can SizeOn replace my post-workout protein shake?

It covers the intra-workout window extremely well; following with a dedicated protein shake post-training is still recommended for optimal recovery, particularly if your total daily protein target needs topping up.

Is this the same formula as the original SizeOn?

The original SizeOn's creatine reputation has been evolved into a more complete hybrid formula — the creatine heritage is intact but the formula is more comprehensive than the original.
