SYNPRO BCAA 40 is a balanced injectable blend of Leucine, Isoleucine, and Valine formulated to reduce muscle breakdown, support anabolic signaling, and enhance recovery.

Main Information

SYNPRO BCAA 40 provides injectable-grade branched-chain amino acids (BCAAs) in the optimal ratio to support muscle protein synthesis, reduce catabolism, and enhance recovery. Leucine, the primary anabolic trigger, activates the mTOR pathway, stimulating muscle growth and repair. Isoleucine and Valine contribute to muscle energy balance and endurance. This formula is especially useful during cutting phases, fasted cardio, recomposition, or any state of caloric deficit or overreaching. BCAA injections offer superior bioavailability over oral powders and bypass digestive degradation — ideal for maximal efficiency.


Scientific Background

SYNPRO BCAA is a targeted injectable blend of the three branched-chain amino acids (BCAAs): Leucine, Isoleucine, and Valine. These essential amino acids have long been recognized as critical building blocks for muscle protein synthesis, energy metabolism, and recovery regulation—particularly in physically active individuals or those under metabolic stress.BCAAs were first isolated and structurally identified in the early 20th century, but it wasn’t until the 1970s and 1980s that their role in exercise metabolism and muscle preservation began to be studied in depth. Researchers discovered that, unlike other amino acids, BCAAs are primarily metabolized in skeletal muscle rather than the liver—highlighting their direct relevance to sports performance and catabolic protection .

What Makes SYNPRO BCAA Unique

  • Combines the full spectrum of BCAAs in injectable form for maximum bioavailability
  • Supports muscle preservation, anabolic signaling, and training performance

Ideal for use in:

  • Fasted workouts or cutting phases
  • Recovery from injury, illness, or overtraining
  • Neuromuscular support during endurance or cognitive fatigue

By delivering BCAAs directly into circulation, SYNPRO BCAA bypasses gastrointestinal breakdown, ensuring faster uptake, higher tissue availability, and immediate metabolic impact when it’s needed most.

Usage Instructions

SYNPROBCAA is an injectable blend of Leucine, Isoleucine, and Valine, designed to support muscle recovery, performance, and anti-catabolic protection. For best results, it should be used around periods of intense training, fasting, or nutritional depletion.

  • Injection Route: Subcutaneous (abdomen or thigh) or intramuscular (glute or deltoid)
  • Needle Size: 29–31G (subQ) or 25–27G (IM)
  • Storage: Refrigerate at 2–8 °C. Protect from light.
  • Reconstitution: If provided as lyophilized powder, reconstitute with bacteriostatic water according to label instructions

Dosage Information

Pre-Workout (Anti-Catabolic / Fasted Training)

  • 0.5–1 mL, injected 20–30 minutes before training
  • Ideal for low-carb sessions, cutting cycles, or morning workouts

Post-Workout (Anabolic Recovery)

  • 0.5–1 mL, injected within 30 minutes post-training
  • Supports muscle protein synthesis and recovery

High-Stress or Catabolic States (e.g., overtraining, illness)

  • 1 mL daily for 5–10 days, then taper to maintenance (2–3×/week)

May be combined with glutamine, electrolytes, or ATP-based injectables for enhanced recovery

Important Warnings

  • Do not exceed 1 mL per day unless under professional supervision
  • Use with caution in individuals with kidney dysfunction, maple syrup urine disease (MSUD), or rare amino acid metabolism disorders
  • Not intended for use during pregnancy or breastfeeding
  • Mild side effects may include site irritation or fatigue if taken without adequate hydration or carbs
  • Ensure adequate hydration and electrolyte balance during use
  • Use sterile technique and rotate injection sites to avoid irritation

Discontinue if signs of allergic reaction, dizziness, or prolonged fatigue occur.
