What is Testosterone Base Micronised?

Testosterone Base Micronised is free (unesterified) testosterone reduced to micron-scale particle size for improved dissolution and bioavailability. No ester modification — direct androgen receptor activation. Used as a pharmacokinetic reference (unesterified baseline), for oil dissolution studies, and for rapid-onset testosterone research. Research use only.

Research Applications

Unesterified Testosterone PK

True baseline testosterone PK — no ester hydrolysis variable, pure free base

Micronisation Research

Particle size effect on dissolution rate, bioavailability, depot formation

Rapid-Onset Androgen

Immediate testosterone activity — acute AR activation without ester delay

Oil Dissolution Reference

Free base solubility in various oil vehicles — formulation development research

Ester vs Base Comparison

Testosterone base vs propionate/enanthate — ester contribution to AUC quantification
