Xtend | Original BCAA | 30 Servings

XTEND Original BCAA is a classic intra-workout amino formula built around one clear objective: deliver a meaningful dose of branched-chain amino acids, add recovery support with glutamine, and include practical electrolytes for hydration during training. This is not a stim-heavy pre-workout and it is not pretending to be an all-in-one performance formula. Its strategy is narrower and more useful for many athletes: support training output and post-training recovery with ingredients that are easy to sip during a session.

The centerpiece is the 7g BCAA complex in a 2:1:1 ratio: 3,500mg L-leucine, 1,750mg L-isoleucine, and 1,750mg L-valine. Leucine is the star from a muscle protein synthesis perspective because it activates mTORC1, the signaling pathway that helps switch on muscle-building processes. The 3.5g leucine dose is firmly in the clinically relevant range and comfortably clears the commonly discussed leucine threshold for stimulating that anabolic signal. In practical terms, this is the part of the formula most directly tied to preserving training quality when you have not eaten recently or when you want amino support around your workout. Isoleucine and valine complete the BCAA triad rather than leaving leucine isolated. That matters, because BCAAs are metabolically interrelated, and using the full 2:1:1 profile is better aligned with sports nutrition practice than using leucine alone in an intra-workout drink. Isoleucine contributes to glucose uptake signaling, while valine plays a role in nitrogen balance and may help with central fatigue dynamics in the broader BCAA context.

L-glutamine is included at 2,500mg. Glutamine has more limited evidence for direct performance enhancement than leucine, and this dose is better understood as supportive than transformative. Where it fits is recovery, especially for athletes in hard training blocks, high sweat environments, or repeated-session schedules where overall recovery demand is elevated. It is not the reason to buy the formula, but it is a sensible add-on in an intra-workout product.

The hydration support is simple and useful: 220mg sodium and 170mg potassium. These are not extreme electrolyte doses, but they are enough to make the formula more functional than a plain amino drink. Sodium and potassium help maintain fluid balance, nerve conduction, and muscle contraction. For anyone who trains hot, sweats heavily, or performs longer sessions, this is one of the more underrated parts of the formula.

Vitamin B6 at 0.64mg is a minor inclusion. It plays a role in amino acid metabolism, but at this dose it is a background support ingredient rather than a headline ergogenic.

The synergy is straightforward: leucine drives the anabolic signal, isoleucine and valine complete the BCAA profile, glutamine broadens recovery support, and electrolytes make the formula more useful during real training conditions. Transparency is a plus here. There are no proprietary blends hiding doses; every meaningful active is disclosed. That matters in a category where many amino products lean on flashy positioning while telling you less.

What should you expect? Day 1, the main experience is practical rather than dramatic: easier hydration during training, a more purposeful intra-workout drink, and less of that flat, depleted feeling after hard sessions. Over 2 to 4 weeks of consistent use, the benefit is less about a sudden performance spike and more about improved session consistency, especially if you train fasted, diet aggressively, or accumulate a lot of weekly volume. The formula’s biggest strength is that it knows exactly what it is: a transparent BCAA-plus-hydration product with a properly dosed leucine core.
