Available Sizes & Variants:

440 grams intra-workout amino acid supplement - convenient for frequent training sessions.

Benefits & Features:

• Delivers amino acids to muscles during workouts.
• Contains a complete amino acid blend and hydrolysed proteins for rapid availability.
• Supports ongoing amino acid supply during tough sessions.
• Designed for daily use around workouts, it maintains amino acid availability during exercise, helping you train harder and finish stronger, even after long or back-to-back sessions.
• Manufactured to high quality standards with patented ingredients.

Trained by JP MPS Max blends complete proteins with patented additions to support training sessions. The mix includes PeptoPro hydrolysed casein, Velositol, Peak O2 mushroom complex, Aquamin minerals and AstraGin, all chosen to boost amino acid availability and nutrient delivery during workouts. Leucine is highlighted as the rate limiting amino acid for muscle protein synthesis, which this formula aims to address. Some athletes pair this peri-workout blend with magnesium glycinate for muscle function, while others use it alongside a protein powder or a pre workout drink.

The Core Ingredient Is: Leucine (Essential Amino Acid)

Leucine is one of the essential amino acids required for normal protein metabolism and tissue maintenance.

This form is free-form and is part of an essential amino acid blend used to support amino acid availability for muscle protein synthesis during activity.

What Does Leucine Do?

Leucine is involved in the initiation of muscle protein synthesis, a process that supports protein turnover in skeletal muscle. This role is consistent with guidance from EFSA on essential amino acids and their functions in normal metabolism.

Studies indicate leucine can contribute to amino acid availability during training, helping to support ongoing protein synthesis and muscle maintenance.
