Proviron 25 (Mesterolone) is supplied as a reference compound for controlled research into androgen receptor (AR) interactions, sex hormone–binding globulin (SHBG) binding dynamics, and comparative endocrine modeling. Each tablet contains 25 mg Mesterolone and is intended strictly for laboratory and educational use.

Research Overview

In research settings, Mesterolone is evaluated as a non-17α-alkylated androgenic reference with notable AR affinity and high SHBG-binding characteristics. It is frequently included in studies that examine how ligand–receptor interactions and SHBG displacement may influence the measurable fraction of steroidal analytes in vitro, as well as exploratory work on aromatase-adjacent pathway modeling under controlled conditions.

Key Research Points

• Used to study androgen receptor binding kinetics and downstream signaling readouts.
• Referenced in models assessing SHBG–ligand competition and free-analyte fractions.
• Included in aromatase-pathway comparative frameworks (receptor-level context only).
• Non-17α-alkylated profile makes it a useful comparator in liver enzyme impact assays.

Observed Laboratory Findings (Reported in Literature)

• Consistent AR engagement with predictable assay curves at tablet-equivalent levels.
• Measurable effects in SHBG-binding competition models under fixed conditions.
• Stable performance in multi-week observation windows with reproducible data capture.

Reference Sampling & Handling

• Form: Oral tablet
• Strength: 25 mg Mesterolone per tablet
