Contraindications: Stanozolol is contraindicated in individuals with active hepatic impairment, prostate or breast carcinoma, hypercalcaemia, or known hypersensitivity to the active ingredient. Women of childbearing potential should not use stanozolol due to virilisation risk. Individuals with pre-existing dyslipidaemia should be aware that stanozolol produces pronounced HDL suppression and LDL elevation.
Side Effects: Oral stanozolol commonly produces elevated hepatic transaminases (ALT, AST), HDL cholesterol reduction, LDL elevation, joint dryness linked to reduced synovial fluid, and androgenic effects including accelerated hair loss in genetically predisposed individuals. Hepatic effects are dose- and duration-dependent, making blast phase length a key management variable.
Monitoring: Obtain a full blood panel — including liver function tests (ALT, AST, GGT), fasting lipid profile, and haematocrit — before beginning a blast phase. Repeat liver function tests at blast midpoint and within one week of stopping stanozolol. If ALT or AST exceeds two times the upper limit of normal, exit the blast phase regardless of planned duration.
PCT: Post-blast and post-cycle testosterone axis recovery support is required when stanozolol is used within a blast stack that includes suppressive base compounds. Standard PCT agents (SERMs such as tamoxifen or clomiphene) should be initiated after the base compound's clearance window has passed, not immediately following stanozolol discontinuation alone, as stanozolol itself is not the primary suppressive agent in most blast stacks.
