AICAR Dosage & Reconstitution Guide (AMPK Fat Loss Peptide Explained)

AICAR

AICAR is a metabolic research compound studied for its ability to activate AMPK, a key cellular energy sensor involved in fat oxidation, glucose uptake, and endurance signaling.

How It Works

AMPK Activation → Fat Oxidation ↑ → Glucose Uptake ↑ → Endurance Support ↑

AICAR mimics a low-energy cellular state, which activates AMPK and shifts the body toward improved metabolic efficiency, greater fat utilization, and enhanced endurance-related signaling.

Real-World vs Clinical Use

Real-World Range

Typical Use1–3 mg daily

GoalMetabolic support + endurance

Clinical / Research Context

Higher ExposureOften discussed at higher total doses

RealitySide effects and tolerability become more limiting

Real-world use generally stays in lower daily ranges for tolerability, while research discussions sometimes reference higher exposure. A gradual build is the cleanest way to assess response.

When & Where to Inject

• Subcutaneous injection
• Common sites: abdomen or thigh
• Often used in the morning or before training
• Rotate injection sites regularly
