Fat Loss Principles

This infographic breaks down 15 core fat loss principles in a simple, easy-to-understand format. It covers calorie balance, the difference between weight loss and fat loss, maintaining muscle, protein, daily movement, high-volume foods, liquid calories, consistency, plateaus, environment, and building habits that support long-term progress.

The Correct GLP-1 Dose
General

The Correct GLP-1 Dose

This infographic explains the idea of finding a GLP-1 β€œsweet spot” rather than automatically chasing stronger appetite suppression or higher doses. It highlights four signs of an effective balance: quieter food noise, normal hunger cues, the ability to meet calorie and protein goals, and manageable side effects.

Units Are NOT Dosage
Getting Started

Units Are NOT Dosage

Units measure volume on the syringe; dosage measures the weight of peptide you actually draw. Shows how 25 units equals 1.25 mg, 2.5 mg or 5 mg depending on concentration, plus the quick formula: units x mg/mL / 100.

Always Use a Fresh Needle β€” Every Injection, Every Time

Why a new sterile needle every time protects both you and your compounds: infection risk, dull and burred tips, inaccurate dosing, scar tissue, and the cross-contamination that happens when one needle moves between vials. Pen needles count too.
