NutraBio Growth Peptides
NutraBio's stimulant-free muscle builder and recovery aid, with 2,400 mg of PeptiStrong and 2,000 mg of dileucine
Growth Peptides is what NutraBio calls its Muscle Accelerator: a capsule formula built to support muscle growth and recovery for people who train hard. A 7-capsule serving has 2,400 mg of PeptiStrong, a peptide ingredient made from fava bean protein, and 2,000 mg of DL-185 dileucine, which is two leucine amino acids joined together. NutraBio adds 50 mg of AstraGin to support nutrient absorption.
The peptides come from food protein, and NutraBio describes the formula as non-hormonal and stimulant-free. Both main ingredients match amounts used in research: in a small 2021 study, 2 g of dileucine raised muscle protein synthesis in young men while 2 g of plain leucine did not, and PeptiStrong was tested at 2.4 g a day for strength recovery in a 30-man trial funded by its maker. Each bottle has 196 capsules, or 28 servings.
