Agovirin Depot (Testosterone Isobutyrate)

by WikiStero.com

Agovirin Depot, also called testosterone isobutyrate, is a testosterone solution in water-based suspension. It does not have an an ester added so it acts relatively quickly.


Size and Packaging

Agovirin Depot is usually available in a box and packaged in 2ml vials (5 vials per box), each vial containing 25mg/ml of testosterone mixed in a crystalline water-based solution.

Agovirin Depot is water-based, so the steroid (which is oil-based) and the water will naturally separate when at rest. For the right dosage, you must shake the box well to suspend the active substance in the water.


Results and Side Effects

For Agovirin Depot’s results and side effects, see the page for testosterone propionate.


Additional Information

Agovirin Depot has a rather unique design that differs from traditional testosterone with oil-based esters.

Once the microcrystalline suspension is injected, crystals form a deposit in the muscle (much like regular testosterone) where they dissolve slowly and release into the bloodstream.

However due to the presence of crystals, this solution is denser and more voluminous and requires a slower injection. The manufacturer recommends using a large needle, or the injections can cause redness and irritation.


It’s preferable to use a slower injection with a traditional-size needle (size 23-25) for cycles based on Agovirin Depot and other combined products.
