GAC — Glutamine, Arginine, and Carnitine — is a triple amino acid injectable that supports fat burning, muscle recovery, immune resilience, and nitric oxide production. A staple in high-performance and weight loss protocols.
Each component of GAC contributes a distinct and complementary set of benefits. Combined in an injectable form, they work synergistically for metabolic, performance, and recovery support.
The most abundant amino acid in the body. Essential for immune function, gut health, and muscle preservation.
A precursor to nitric oxide — the molecule that dilates blood vessels, improves blood flow, and drives cardiovascular and sexual health.
Transports fatty acids into the mitochondria where they are burned for energy — making it essential for fat metabolism and cellular energy production.
GAC is commonly used alongside GLP-1 therapy (semaglutide, tirzepatide) to enhance fat utilization, preserve lean muscle during caloric restriction, and support metabolic function.
Athletes use GAC to improve blood flow, reduce recovery time between sessions, and preserve muscle mass — especially during high training volumes or caloric deficits.
GAC pairs naturally with TRT and peptide protocols. Arginine's GH-stimulating effects complement sermorelin and ipamorelin, while carnitine supports the metabolic improvements from hormone therapy.
Glutamine is a primary fuel source for immune cells. Patients recovering from illness, surgery, or stress benefit from glutamine-driven immune support via GAC.
GAC stands for Glutamine, Arginine, and Carnitine — three amino acids combined in a single injectable formula. Each contributes complementary benefits: glutamine for immune and gut support, arginine for nitric oxide and blood flow, and carnitine for fat metabolism and energy production.
Yes. GAC is a non-controlled amino acid formulation available to patients in all 50 states via telehealth. No Florida residency required.
Carnitine directly enhances the transport of fatty acids into mitochondria for fat burning. Arginine improves blood flow and nitric oxide levels, which supports exercise performance and metabolic efficiency. Combined, GAC is a useful adjunct to GLP-1 therapy and other weight loss protocols.
Typically 2–3 times per week via subcutaneous or intramuscular injection. The frequency depends on your protocol goals. Dr. Paul will recommend the appropriate schedule as part of your overall plan.
GAC is well-tolerated in most patients. Some may notice mild injection site discomfort. Arginine can occasionally cause mild GI upset at high doses — uncommon with injectable forms. No significant adverse effects are expected in healthy adults at standard doses.
GAC is available via telehealth nationwide and fits naturally into most of our protocols. Book a free 15-minute consultation to discuss whether it's right for your program.
