The best Primo 100 (Primobolan) cycle for lean muscle growth typically lasts 8-12 weeks and is favored for its mild yet effective results. For beginners, a dosage of 400-600 mg per week is common, while advanced users may go up to 800 mg. Primo 100 helps maintain muscle mass while burning fat, making it ideal for lean gains without excess bulk. It's often stacked with Testosterone for enhanced effects, promoting muscle hardness and improved definition. Always follow proper dosing guidelines and consult a healthcare professional before starting any cycle.
