Efectiv Nutrition Peptide 120 Capsules With 2400mg PeptiStrong and Vitamin D3
Efectiv Nutrition Peptide is a two ingredient capsule formula. Each four capsule serving delivers 2400mg PeptiStrong and 75µg vitamin D3. The 120 capsule bottle provides 30 servings.
PeptiStrong is a peptide network discovered by Nuritas using AI and produced from hydrolysed fava bean protein. It is the dose used in the published clinical work, where two studies reported improved power output by up to 130%, increased performance by up to 54% and a 47% increase in strength recovery, alongside reduced muscle soreness and suppressed plasma myostatin. A third study reported muscle protein synthesis rates four times greater than the same amount of whey protein during remobilisation. The references are listed in full on this page.
The vitamin D3 is vegan, sourced from lichen rather than lanolin, at 75µg or 1500% of the nutrient reference value. Vitamin D contributes to the maintenance of normal muscle function, contributes to the maintenance of normal bones, and contributes to the normal function of the immune system.
Peptide suits hybrid athletes, functional fitness and HYROX style training, and anyone adding PeptiStrong to an existing stack in capsule form rather than powder. It is vegan friendly, contains no known allergens, and results still depend on consistent training and adequate protein intake.
