Contraindications: Maste 150 is contraindicated in individuals with known hypersensitivity to Drostanolone Propionate or any component of the oil vehicle. Not for use in women of childbearing potential, pregnant or nursing individuals, or males with confirmed prostate pathology. Individuals with pre-existing cardiovascular disease, polycythemia, or significant hepatic impairment should not use this product.
Side Effects: Androgenic effects including accelerated male-pattern hair loss, increased sebum production, and potential virilisation in sensitive individuals are the most commonly reported adverse effects. Lipid profile disruption — particularly suppression of HDL cholesterol — is expected with androgen administration; baseline and mid-cycle lipid panels are strongly advised. Haematocrit elevation may occur with sustained use; haemoglobin monitoring is recommended during extended contest prep cycles.
Monitoring: Pre-cycle bloodwork should include testosterone (total and free), LH, FSH, lipid panel, haematocrit, liver enzymes, and PSA. Mid-cycle assessment at weeks 4–5 of a contest prep block allows dose adjustment decisions to be made on objective biomarker data rather than subjective physique alone. Blood pressure monitoring at least every two weeks is recommended during high-frequency EOD injection phases.
PCT: Endogenous testosterone suppression is expected following exogenous androgen administration. Because the propionate ester clears within approximately one week of the final injection, post-cycle therapy (typically a SERM-based protocol such as Tamoxifen or Clomiphene) can be initiated promptly after competition. Duration and protocol intensity should be guided by bloodwork confirming LH/FSH and endogenous testosterone recovery trajectory.
