This aims to give you a full amino acid profile for general recovery and protein support, but the doses are spread thin. The entire blend totals 2,800 mg across 4 capsules, which means individual aminos like **L-Leucine** (205 mg), **L-Glutamine** (204 mg), and **L-Arginine** (276 mg) land far below their studied clinical ranges — leucine needs 2,000–3,000 mg to trigger muscle protein synthesis, and glutamine research uses 5,000–15,000 mg.
The blend includes protein isolates (whey, soy, casein) as amino acid sources alongside free-form aminos, plus 13 mg of **Vitamin B6** to support amino acid metabolism. You're getting a broad spectrum of all essential and non-essential aminos, but the amounts reflect what you'd get from roughly a few grams of protein.
If your goal is targeted support for muscle recovery, sleep, or any specific amino acid benefit, the individual doses here are too low to match what clinical research has studied. This functions more as a general amino acid top-up than a performance supplement.
