Scitec BCAA + Glutamine Xpress

🧬 5000mg of BCAAs per daily dose — the 2:1:1 leucine-dominant ratio

The 2:1:1 BCAA ratio (L-leucine 2500mg / L-isoleucine 1250mg / L-valine 1250mg at the 12g daily dose) is the benchmark ratio in BCAA supplementation research. Leucine at 2500mg per daily dose provides a meaningful mTOR activation stimulus — mTOR (mechanistic target of rapamycin) is the master regulator of muscle protein synthesis that is directly and acutely activated by leucine. The 2500mg leucine dose per day of BCAA + Glutamine Xpress is positioned within the 2 to 4g per dose range associated with significant mTOR signalling in research. L-isoleucine and L-valine complement leucine’s anabolic signalling with roles in glucose metabolism, energy production and muscle glycogen replenishment respectively.

🔋 5000mg of L-Glutamine per daily dose — the most abundant amino acid in muscle

L-glutamine is the most abundant free amino acid in skeletal muscle — constituting approximately 60% of the total free amino acid pool in muscle tissue. During intense exercise, muscle glutamine concentrations decline significantly as the body draws on glutamine for fuel, immune function and acid-base balance support. Free-form L-glutamine supplementation at 5000mg per daily dose directly replenishes this training-induced decline, supporting muscle glycogen resynthesis, immune system integrity during high training volumes and the maintenance of a positive nitrogen balance throughout the recovery period.

⚡ Taurine 300mg per daily dose — exercise support

Each daily dose provides 300mg of taurine — an addition that complements the BCAA and glutamine matrix with taurine’s roles in muscle osmotic regulation, antioxidant protection against exercise-induced oxidative stress and cardiovascular support. While 300mg per daily dose is a moderate taurine addition compared to the 990mg in Scitec 100% Whey Protein Professional, it provides a consistent taurine contribution at every training session when consumed as a daily intra-workout drink.

💧 Intra-workout refreshing drink format — the consumption advantage

The powder-in-water format is specifically designed for intra-workout consumption — sipping 300ml (or more, diluted to preference) of a flavoured amino acid drink throughout a training session provides continuous BCAA and glutamine availability during the training bout itself. Unlike pre-workout capsule supplements consumed in a single dose, the intra-workout drink format maintains elevated plasma amino acid levels throughout the duration of the session — particularly relevant for longer training sessions exceeding 60 minutes where amino acid oxidation during exercise becomes a meaningful contribution to energy expenditure.

🚫 Sugar-free, gluten-free, vegan-compatible

BCAA + Glutamine Xpress is sweetened with sucralose and acesulfame K — both zero-calorie sweeteners — and contains no added sugar in the ready-to-drink format. Gluten-free per EU regulations. The amino acids (L-leucine, L-isoleucine, L-valine, L-glutamine) are produced through fermentation — no animal-derived protein hydrolysis — making the formula compatible with vegan dietary frameworks.

🎯 Goal guide

🏋️ Mass gain: 2 servings/day (12g) — 1 intra-workout + 1 post-workout or between meals. 5000mg BCAAs and 5000mg glutamine support the anabolic and recovery environment under progressive overload.

🔥 Weight loss / cutting: 1 to 2 servings/day. BCAA supplementation during caloric restriction blunts exercise-induced muscle protein breakdown, helping preserve lean mass during a deficit.

⚖️ Endurance and body recomposition: 1 serving/day intra-workout. Sustained BCAA availability during long sessions; glutamine for immune support and glycogen recovery.

Serving suggestion

Dissolve 1 serving (6g = ⅔ scoop) in 300ml of cold water. Mix or shake well. Consume 1 serving before or during training, or between meals. At the full daily dose, consume 2 servings per day. Adjust water volume to taste — a more diluted preparation (400 to 500ml per 6g) provides a lighter, more refreshing intra-workout drink for longer training sessions.

Best times to enjoy it

⏰ Before training — pre-loading plasma amino acids

Consuming 1 serving 20 to 30 minutes before training pre-loads plasma BCAAs, ensuring elevated leucine and BCAA availability from the very first set. Pre-training BCAA consumption reduces the degree of muscle protein breakdown during the training session itself — particularly relevant for fasted or semi-fasted morning training.

🏋️ During training — intra-workout sustained delivery (primary recommendation)

Sipping BCAA + Glutamine Xpress throughout the training session (over 45 to 90 minutes) provides continuous plasma amino acid replenishment during the period of active amino acid oxidation. For sessions exceeding 60 minutes, intra-workout BCAA consumption is particularly effective at maintaining the plasma leucine levels needed for continuous mTOR signalling and muscle protein synthesis.

☀️ Between meals — inter-meal amino acid maintenance

On rest days or at times of day when the next meal is more than 3 to 4 hours away, consuming a serving of BCAA + Glutamine Xpress provides a zero-calorie (when mixed with water) amino acid contribution that maintains plasma BCAA levels and supports muscle protein synthesis without disrupting dietary phases or caloric targets.

Q1 — What is the 2:1:1 BCAA ratio and why is it the standard?

The 2:1:1 ratio refers to 2 parts L-leucine for every 1 part L-isoleucine and 1 part L-valine. This ratio mirrors the approximate natural proportions of BCAAs in high-quality animal proteins — including whey protein — and is the ratio used in the majority of peer-reviewed BCAA supplementation research from which efficacy evidence is drawn. Leucine is prioritised at double the isoleucine and valine content because leucine is the primary activator of the mTOR signalling pathway that triggers muscle protein synthesis — the biochemical mechanism most directly associated with BCAA supplementation’s performance benefit. Higher-ratio products (4:1:1 or 8:1:1) provide more leucine per serving but less isoleucine and valine, reducing the breadth of the BCAA effect beyond mTOR signalling.

Q2 — Why combine BCAAs and glutamine in the same product rather than using separate supplements?

BCAAs and glutamine are the two most consumed amino acid supplements in the sports nutrition market — and their combination is particularly logical because they address complementary and synergistic mechanisms. BCAAs (particularly leucine) drive muscle protein synthesis — they are the anabolic stimulus. Glutamine supports the recovery infrastructure — immune function, nitrogen balance, glycogen replenishment and the maintenance of the cellular environment in which that protein synthesis can occur. Consuming both simultaneously — as a single intra-workout drink — ensures that both the anabolic signal and the recovery substrate are available throughout the training session at the moment of greatest relevance.

Q3 — Is BCAA + Glutamine Xpress suitable for vegans?

Yes. The amino acids in BCAA + Glutamine Xpress (L-leucine, L-isoleucine, L-valine and L-glutamine) are produced through microbial fermentation — a process that uses plant-based fermentation substrates rather than animal protein hydrolysis. The taurine is also synthetically produced. The sweeteners (sucralose, acesulfame K) and acidity regulator (citric acid) are synthetic and vegan-compatible. The formula contains no animal-derived ingredients, making it fully compatible with vegan dietary frameworks.

Q4 — How does BCAA + Glutamine Xpress compare to adding extra BCAAs to a protein shake?

Protein shakes — including Scitec 100% Whey Protein Professional (22g per 30g scoop) — already contain naturally occurring BCAAs from their whey protein matrix (approximately 4g BCAAs per 22g protein from the 15.6g BCAAs per 100g declared). Adding BCAA + Glutamine Xpress provides BCAAs and glutamine in a free-form (already dissolved in water) format that reaches plasma faster than the protein-bound BCAAs in a shake, and provides a simultaneous 2500mg dose of free-form L-glutamine that no standard protein shake delivers at equivalent levels. The ideal use case is BCAA + Glutamine Xpress as an intra-workout drink during the training session, with a protein shake consumed immediately after — covering different timing windows with optimally formatted amino acid sources.

Q5 — With 100 single servings per 600g bag, how long does it last?

At 1 serving (6g) per training day — the most common protocol for athletes who consume it as an intra-workout drink — 100 servings provides 100 training days of supply. For a typical 5-day-per-week training schedule, this represents approximately 20 weeks (5 months) of supply from a single 600g bag. At the full recommended daily dose of 2 servings (12g), 50 daily doses provides approximately 10 weeks of supply at the same 5-day-per-week frequency.
