Testosterone Base (100mg/mL) is the non-esterified form of testosterone, known for its immediate activity in research involving rapid hormonal response and direct androgen receptor engagement. Without ester modification, this compound offers the shortest possible onset and duration of action, ideal for acute-phase studies.
Testosterone Base is structurally identical to endogenous testosterone, allowing researchers to investigate direct receptor binding, gene transcription activation, and metabolic breakdown without interference from ester hydrolysis. Apextra Labs supplies this preparation as a sterile suspension or oil-based injectable solution at 100mg/mL for maximal accuracy in acute dosing models.
