Contraindications: Not intended for use by individuals under 21 years of age. Avoid if pregnant, nursing, or managing active hepatic conditions. Individuals with a personal or family history of hormone-sensitive conditions should not use SARM stacks. Cardarine is a research compound — not approved for human therapeutic use by the FDA or EMA.
Side Effects: Reported effects in research literature include transient increases in HDL cholesterol and mild alterations to liver enzyme values at higher doses. Animal carcinogenicity data from high-dose, long-duration studies remain a subject of ongoing scientific discussion — researchers should weigh this literature before designing protocols. Stack-specific androgenic side effects (acne, mood changes, libido fluctuation) are attributable to the SARM partners, not to Cardarine.
Monitoring: Obtain a full blood panel including lipid profile, liver enzymes (ALT/AST), and HPTA markers (LH, FSH, testosterone) before beginning any SARM stack. Repeat at week 4 and at cycle conclusion. Tracking both androgenic and metabolic biomarkers is especially important in multi-compound cutting or bulking stacks.
PCT: Post-cycle therapy requirements are determined by the androgenic compounds in the stack. Ostarine-only cutting stacks may require a mild SERM-based PCT (e.g., Nolvadex 20 mg/day for 4 weeks); LGD + RAD bulking stacks typically warrant a full PCT protocol. Cardarine does not require its own PCT but should be discontinued at the same point as the androgenic compounds in the stack.
