contraindications: Nandrolone Decanoate is contraindicated in individuals with prostate carcinoma, breast carcinoma, nephrotic-stage kidney disease, active hepatic impairment, hypercalcaemia, or known hypersensitivity to nandrolone or the sesame/arachis oil vehicle. Pregnancy and breastfeeding are absolute contraindications. Individuals with a personal or family history of thromboembolic events should not use injectable androgens without haematological clearance.
side_effects: Androgenic effects including acne, accelerated scalp hair recession in genetically predisposed individuals, and virilisation in women. Cardiovascular: adverse shifts in HDL/LDL lipid ratios documented by NMR lipid profiling; left ventricular wall thickening with prolonged supraphysiological exposure. Endocrine: HPTA suppression requiring managed PCT. Prolactin elevation is specific to 19-nor compounds and may require dopamine agonist management (e.g. cabergoline) in susceptible users. Injection-site reactions including transient warmth and minor bruising are expected with repeated ampoule-based dosing.
monitoring: Baseline and on-cycle bloodwork should include: full blood count (haematocrit and haemoglobin), comprehensive metabolic panel, lipid profile, serum testosterone (total and free), estradiol (LC-MS/MS method preferred), prolactin, and PSA in men over 35. Monitoring intervals of every 6–8 weeks during active stacking protocols are recommended by sports medicine practitioners. DEXA or body-composition assessment every 12 weeks aids objective tracking of lean-mass response.
pct: Post-cycle therapy should begin after adequate plasma clearance of all long-ester compounds in the stack. Nandrolone Decanoate's active half-life necessitates waiting approximately 2–3 weeks after the last ampoule before initiating SERMs (tamoxifen or clomiphene). Prolactin must be tested before SERM therapy commences; elevated prolactin detected post-cycle indicates cabergoline is needed concurrently. Full hormonal panel reassessment at 4 and 8 weeks post-PCT guides return-to-baseline confirmation.
