AOD-9604 5mg + SLU-PP-332 5mg — Self-Injection Pen (3 Month Supply)

Opti-Lean pairs two fat-metabolism molecules in one pen: AOD-9604, the GH fragment that stimulates lipolysis without affecting blood sugar, and SLU-PP-332, an "exercise-mimetic" ERR agonist studied for raising metabolic rate and fat oxidation. Two pathways, one pen. Three-month supply (300 clicks), compounded in a US-licensed pharmacy and shipped cold-chain, refrigerator-stable. For use under licensed-provider supervision.

Prescription therapy. A licensed provider reviews every order before it ships — your free consultation is included.

About Opti-Lean Pen

Opti-Lean Pen is a blend of AOD-9604 and SLU-PP-332, supplied as a prefilled, multi-dose injection pen. Combining them in one preparation means one injection instead of 2.

In published research, these compounds have been studied for fat metabolism, body composition, energy expenditure, and endurance. Research interest is not proof of benefit, and individual results vary.

It is a prescription therapy: a licensed provider reviews every order before it ships.
