Main Information

SYN MASS AMINO 555 delivers a broad spectrum of injectable amino acids tailored for muscle hypertrophy, cellular repair, and athletic recovery. It includes key anabolic drivers likeL-Leucine, L-Isoleucine, and L-Lysine, combined with Glutamine, Arginine, Citrulline, Ornithine, Glycine, and Taurin — supporting everything from protein synthesis and nitrogen balance to joint regeneration ad immune modulation. This makes it a versatile tool for bodybuilders, athletes, or anyone recovering from training plateaus, injury, or intense metabolic stress.

Can be used as a standalone recovery aid or stacked in muscle-building programs.

Scientific Background

SYN MASS AMINO 555 is a broad-spectrum injectable amino acid blend formulated to support muscle hypertrophy, post-exercise recovery, and connective tissue regeneration. It is built on the combined effects of essential and conditionally essential amino acids, each selected for their role in anabolic signaling, tissue repair, and metabolic recovery.

Amino acids were first isolated in the early 19th century as the building blocks of proteins, but their unique physiological roles were uncovered progressively through the 20th century. By the 1970s, researchers had identified specific amino acids—like Leucine and Glutamine—as regulators of muscle metabolism and immune resilience. Modern injectable formulations, like SYN MASS AMINO 555, are designed to deliver these nutrients directly into the bloodstream, bypassing digestive breakdown and allowing for rapid bioavailability in performance or recovery states.

The BCAAs L-Leucine, L-Isoleucine, and L-Lysine drive muscle protein synthesis and nitrogen retention. Glutamine helps maintain gut integrity and immune function during physical stress [2]. Arginine and Citrulline enhance blood flow and nutrient delivery via nitric oxide production [3]. Ornithine aids in ammonia clearance, reducing fatigue, while Glycine supports collagen synthesis and connective tissue healing [4]. Taurine contributes to cellular stability, electrolyte regulation, and antioxidant defense [5].

SYN MASS AMINO 555 is ideal for use during plateau phases, injury rehab, or high-frequency hypertrophy training where rapid recovery and anabolic efficiency are essential.

Usage Instructions

SYN MASS AMINO 555 is an injectable amino acid complex formulated to support muscle building, recovery, and tissue regeneration. It is intended for subcutaneous (subQ) or intramuscular (IM) administration, depending on the desired absorption speed.

Route: Subcutaneous (e.g. abdomen, flank) or intramuscular (e.g. glute, deltoid)
Needle size: 29–31G (subQ) or 25–27G (IM)
Timing: Use in the morning, post-training, or on rest days for recovery support
Cycle length: 4–6 weeks of use, followed by a 1–2 week break if needed
Storage: Store refrigerated at 2–8 °C. Do not freeze. Use within 30 days after opening

Can be used alone or stacked with other injectables (e.g., SYN POWER BOOST or B-vitamin support) depending on training goals.

Dosage Information

Muscle Growth / Hypertrophy Phase

1 mL, 3–5× per week post-training or on high-volume workout days
Ideal when combined with protein-rich meals and resistance training

Recovery / Overtraining Support

0.5–1 mL, 2–3× per week on rest or deload days
Supports tissue repair, nitrogen balance, and systemic recovery

Rehabilitation / Injury Recovery

0.5 mL daily or every other day for 2–4 weeks
Combine with collagen-supportive nutrients or physical therapy protocols

Always inject slowly and rotate sites to avoid irritation. Massage the area gently post-injection if subQ.

Important Warnings

Do not use if allergic to any amino acid in the formula or if you have a known metabolic disorder involving amino acid metabolism (e.g., maple syrup urine disease, PKU)
Not recommended during pregnancy or breastfeeding unless prescribed
Use caution in individuals with kidney dysfunction, especially when on high-protein diets
May cause mild injection site soreness, tingling, or flushing in some users
Do not combine with other injectable amino blends without professional guidance
Discontinue if you experience unusual fatigue, rash, or persistent discomfort

For training-related recovery and performance support only. Keep out of reach of children. Use under supervision in structured cycles.
