Hype Score
0 = legit, 10 = all hype
"It's an essential amino acid (EAA) powder with all nine amino acids, electrolytes, and some nootropic ingredients."
Consumer advice
If you're training hard and want EAA support, this product will work—but compare it to cheaper generics first (Optimum Nutrition EAA, Scivation Xtend, or basic BCAA + electrolyte combos). The nootropic additions (likely underdosed in a proprietary blend) are not worth the premium. Take it intra-workout or post-workout for best results. Don't expect dramatic muscle growth without proper training and diet. If budget is tight, whole protein powder or eating adequate protein is a better value."
Claims vs Evidence
MODERATE2 of 6 claims supported by evidence.
"support muscle growth"
Partial
EAAs stimulate protein synthesis, but growth requires training and caloric surplus.
Based on: Leucine, Isoleucine, Valine (BCAAs), all nine essential amino acids
"accelerate muscle recovery and reduce soreness"
Supported
Clinical evidence supports EAAs for recovery when used post-workout.
Based on: Leucine, Isoleucine, Valine (BCAAs), all nine essential amino acids

Electrolytes help hydration; BCAA fatigue-delay is modest and context-dependent.
Based on: electrolyte blend, BCAAs
"enhance lean muscle preservation"
Supported
EAAs prevent catabolism during fasting or deficit; evidence is solid.
Based on: all nine essential amino acids
"boost neurotransmitter production and improve focus"
Stretch
Amino acids are precursors, but doses and bioavailability unclear in blend.
Based on: Phenylalanine, Tryptophan, nootropic blend (undisclosed)

Ingredients
Based on peer-reviewed research from PubMed and Examine.com
Lysine & Threonine
Essential amino acid found in food and supplements; limited clinical evidence for most popular health claims.
Research-backed dose: No established dose from provided studies
Phenylalanine & Tryptophan
Antioxidant shown to reduce nerve pain, oxidative stress, and inflammation in diabetic conditions.
Research-backed dose: 300–600 mg daily based on study doses
Methionine & Histidine
Traditional herb with modest evidence for blood sugar control and lactation support. Testosterone effects are unclear.
Research-backed dose: 500–1800 mg daily depending on use case (lactation, blood sugar, testosterone)
Electrolyte Blend
Broccoli leaf extract shows early promise for liver and metabolic health, but human evidence is lacking.
Research-backed dose: No established dose (insufficient research data)
Nootropic Blend
Broccoli leaf extract shows early promise for liver and metabolic health, but human evidence is lacking.
Research-backed dose: No established dose (insufficient research data)
Amino acids found in protein-rich foods. Evidence for direct performance benefits is weak and inconsistent.
Research-backed dose: No established dose (insufficient research data)
Phenylalanine
Antioxidant shown to reduce nerve pain, oxidative stress, and inflammation in diabetic conditions.
Research-backed dose: 300–600 mg daily based on study doses
Essential amino acid; early research suggests gut hormone and appetite effects, but human evidence is limited.
Research-backed dose: No established dose from provided studies for oral supplementation
nootropic blend (undisclosed)
Broccoli leaf extract shows early promise for liver and metabolic health, but human evidence is lacking.
Research-backed dose: No established dose (insufficient research data)
formulation
A pill coating that bypasses stomach acid, releasing ingredients in the intestine for better absorption or less irritation.
Research-backed dose: No established dose — enteric coating is a delivery technology, not an active ingredient
