XTEND by Scivation is one of the most established BCAA and intra-workout brands in the supplement industry — the formula that helped define the modern intra-workout category. XTEND Original delivers 7g of branched-chain amino acids (BCAAs) per serving in the clinically studied 2:1:1 ratio alongside electrolytes, glutamine, and citrulline malate — providing a comprehensive intra-workout support formula for muscle endurance, recovery, and hydration during training. Bulldog Nutrition is an authorized Canadian and US retailer of XTEND, backed by 10+ years in the supplement industry.
XTEND Original is one of the few BCAA products to earn genuine category-leading status — the 7g BCAA dose at a 2:1:1 leucine:isoleucine:valine ratio reflects the research-supported threshold for intra-workout amino acid efficacy, combined with electrolytes for hydration and zero sugar for clean sipping throughout a training session. XTEND Pro offers a higher-protein BCAA formula for athletes who want additional protein alongside their intra-workout aminos.
Why XTEND: One of the most proven and widely used intra-workout BCAA formulas available — a category standard with decades of athlete use and strong brand credibility in serious training communities. The 7g BCAA dose is one of the highest in its category, and the zero-calorie formula makes it practical for both bulking and cutting phases.

Frequently Asked Questions
What is XTEND BCAA and when should I take it?
XTEND Original is a branched-chain amino acid (BCAA) intra-workout formula delivering 7g of BCAAs per serving in the 2:1:1 ratio (leucine:isoleucine:valine), alongside glutamine, citrulline malate, and electrolytes. It is designed to be sipped during training — supporting muscle protein preservation during workouts, reducing muscle breakdown during calorie-restricted training, supporting hydration via electrolytes, and extending training endurance. Mix one scoop in 16–24oz of water and sip throughout your training session.
Is XTEND BCAA good for fat loss phases?
Yes — XTEND is popular during cutting phases for several reasons: it is zero calorie (no sugar or fat), it provides BCAAs to support muscle protein preservation during caloric deficits, and the electrolytes support hydration which can be a challenge in a fat loss phase with reduced carbohydrate intake. Intra-workout BCAA use during a cut is one of the most practical tools for minimizing muscle loss while maintaining training intensity on reduced calories.
