Contraindications: Enandrol must not be used by individuals with androgen-sensitive prostate or breast carcinoma, active hepatic impairment, polycythaemia, or known hypersensitivity to Testosterone Enanthate or any excipient in the formulation. Use during pregnancy or breastfeeding is absolutely contraindicated. Adolescents with open epiphyseal plates should not use pharmacological testosterone preparations.
Side Effects: Elevated haematocrit, erythrocytosis, acne, seborrhoea, androgenic alopecia, and injection-site reactions are the most commonly reported adverse effects. Aromatisation to oestradiol may produce gynaecomastia or fluid retention at doses above physiological replacement; an aromatase inhibitor may be required. Suppression of endogenous LH and FSH production leads to testicular atrophy and reduced spermatogenesis during the active cycle.
Monitoring: Serum testosterone, LH, FSH, haematocrit, PSA (in males over 40), and hepatic enzyme panels should be assessed at baseline and at 6–8-week intervals. Blood pressure monitoring is recommended throughout, given testosterone's known impact on fluid balance and red-cell mass. Lipid panels (LDL/HDL) should be reviewed given androgenic effects on lipoprotein metabolism.
PCT: Following cessation of Enandrol, a structured post-cycle therapy (PCT) protocol using a SERM such as tamoxifen or clomiphene is required to restore endogenous testosterone production. Timing of PCT initiation should be guided by the multi-day active window of the enanthate ester; allow serum levels to decline adequately before starting PCT agents. Consulting a licensed physician before undertaking any testosterone protocol is strongly advised.
