Caymus Nutrition | Intra BCAA+EAA

Kaymus Intra BCAA+EAA is a stim-free intra-workout amino and hydration formula built around one clear idea: preserve training quality while you are still under the bar, on the machine, or deep into conditioning work. Instead of relying on caffeine or dressing up the label with underdosed extras, this formula focuses on three performance pillars that matter during training: essential amino acid availability, fluid-electrolyte support, and cellular hydration.

The amino profile is the center of the formula. You get 3,500mg L-Leucine, 1,750mg L-Isoleucine, and 1,750mg L-Valine for a full 7g BCAA matrix in the classic 2:1:1 ratio. Leucine is the lead signal for muscle protein synthesis through mTORC1 activation, and 3.5g is a meaningful dose that exceeds the leucine threshold commonly discussed in sports nutrition. That matters because leucine is the amino acid most responsible for telling muscle tissue that building and repair should begin. Isoleucine and valine complete the BCAA triad, supporting nitrogen balance and helping avoid the imbalance that can occur when leucine is used alone.

What elevates this beyond a basic BCAA drink is the inclusion of the remaining EAAs: 1,000mg L-Threonine, 1,000mg L-Lysine, 500mg L-Histidine, 300mg L-Phenylalanine, 150mg L-Methionine, and 50mg L-Tryptophan. This is an important formulation decision. BCAAs alone can trigger anabolic signaling, but muscle protein synthesis still requires all nine essential amino acids as substrate. In plain terms: leucine can flip the switch, but EAAs are the building material. This formula gives you both the signal and the raw materials.

Taurine at 2,000mg is one of the strongest inclusions here. That is not a token dose. Taurine functions as an osmolyte, helping regulate cell volume and hydration status, and human data supports benefits for endurance exercise performance. During long sessions or heavy sweat loss, taurine helps maintain better cellular fluid balance, which often translates to a more stable, less flat feeling as training progresses.

The hydration side is also legitimately useful. Sodium is set at 200mg, potassium at 100mg, and calcium at 550mg, with 1,000mg raw coconut water powder for additional hydration support. Sodium and potassium work together through the electrochemical gradient and Na+/K+-ATPase system to support muscle contraction, nerve signaling, and fluid distribution. Calcium is less common in intra formulas at this level; while it is not an acute ergogenic ingredient in the same way as sodium, it is essential for muscle contraction physiology. For hard trainers who sweat heavily, this profile gives the formula real functional value.

The main transparency caveat is that formula metadata flags a proprietary blend, but the active ingredients and doses provided here are disclosed. Based on the verified actives, this reads far more transparently than many category-average amino products, which often hide exact amino and electrolyte amounts behind blend names.

What should you expect? On day 1, this feels like better session stability than a dramatic rush: easier sipping, less drop-off in output, and better hydration through the back half of training. After 2-4 weeks of consistent use, especially if you train frequently or fasted, the value becomes more obvious: reduced mid-session fade, better recovery between sessions, and more productive training volume because your amino intake and hydration are no longer afterthoughts.
