Compound type: Short-Acting Testosterone Ester — AR Agonist (~2-day half-life) CAS Number: 57-85-2
What is Testosterone Propionate?
Testosterone Propionate (TP) is the shortest-acting ester form of testosterone (~2-day half-life), providing rapid-onset androgen delivery and fast washout vs. longer esters. Historically the first synthetic testosterone ester used in clinical medicine (1930s). TP is preferred in research models requiring precise control of androgen exposure windows, acute HPG axis response studies, and washout experiments. Produces identical testosterone pharmacology (AR agonism, aromatisation, 5α-reduction) to other esters with different pharmacokinetic profiles.
Research Applications
Short-Acting Androgen Research
Rapid-onset/fast-washout model for acute testosterone pharmacology
Acute HPG Axis Dynamics
LH/FSH suppression and recovery at short timescales vs. longer esters
Ester PK Reference
~2-day half-life benchmark for comparative ester pharmacokinetic studies
When is Testosterone Propionate preferred over longer esters?
TP’s ~2-day half-life makes it preferred for research requiring rapid androgen onset, precise exposure window control, and fast washout. It’s used for acute HPG axis studies, androgen window experiments, and pharmacokinetic comparisons against Enanthate (~5 days) or Cypionate (~8 days).
