Oldest testosterone preparation. Fastest onset. Used in research requiring rapid testosterone elevation. High injection frequency limits clinical practicality.
Pure unesterified testosterone in aqueous suspension. No ester = immediate absorption. Half-life measured in hours (~2–4h). Fastest onset of all testosterone forms. Water-based — more painful injection than oil-based esters. Same AR mechanism as all testosterones.
No ester; 2–4h half-life; immediate onset; water-based suspension; daily/twice-daily dosing.
Research data is not a treatment plan. If you are considering Testosterone Suspension, the questions that matter are whether it suits your history, your labs and your goals. That is a conversation with a licensed physician, not a lookup.
