SYN – GFL “Get Fuckin’ Lean” Injectable L-Carnitine

What is GFL – Injectable L-Carnitine by SYN Pharma?

GFL by SYN Pharma is a high-purity injectable form of **L-Carnitine**, a naturally occurring amino acid derivative that plays a critical role in fat metabolism and energy production. L-Carnitine facilitates the transport of long-chain fatty acids into the mitochondria, where they are oxidized to produce energy. This makes it a valuable tool for those pursuing fat loss, improved endurance, and enhanced recovery.

Injectable L-Carnitine offers superior bioavailability compared to oral forms, allowing for faster absorption and greater effectiveness in performance-focused and aesthetic protocols.

Injectable L-Carnitine Benefits

Research and athlete use have shown that injectable L-Carnitine may support the following outcomes:

• Enhances fat oxidation: improves the body’s ability to convert stored fat into usable energy;
• Increases endurance and stamina: supports prolonged physical performance by sparing muscle glycogen;
• Improves recovery: helps reduce muscle soreness and fatigue post-training;
• Supports lean muscle retention: especially during calorie-deficit phases such as cutting or contest prep;
• May improve insulin sensitivity and nutrient utilization: useful for metabolic support during recomposition plans.

Potential Side Effects

L-Carnitine is generally well-tolerated, especially when administered within standard dosing protocols. However, some users may experience:

• Injection site irritation or mild discomfort;
• Increased sweating or body odor in rare cases (due to metabolic byproducts);
• Nausea or upset stomach (less common with injectable forms);
• Restlessness or insomnia if taken late in the day.

Contraindications

Do not use GFL if you have the following conditions without medical supervision:

• Severe kidney disease;
• Hypersensitivity to carnitine or injection preservatives;
• Thyroid conditions or hormone imbalances unless approved by a physician.

GFL Dosage and Administration

Typical research and athletic-use dosages range from **200 mg to 1,000 mg per day**, administered intramuscularly (IM) or subcutaneously (SC). GFL is best injected 30–60 minutes before physical activity for performance enhancement or taken daily during cutting protocols.

Cycle duration often lasts **6–8 weeks**, with some protocols extending to 12 weeks depending on goals and tolerance.
