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
