Sterandryl Retard, a.k.a. testosterone hexahydrobenzoate, is testosterone with a hexahydrobenzoate ester that's both short and fast-acting. Sterandryl Retard is often referred to as Test Hexa, or by its Portuguese name Testormon Depositum. Rarely seen independently, Test Hexa is probably best known for its inclusion in Spectriol, a steroid blend that includes Methandriol Dipropionate (20 mg), Nandrolone Phenylpropionate (15 mg) and equal parts (10 mg) of testosterone propionate, cypionate, and hexahydrobenzoate.

More specifically, testosterone hexahydrobenzoate is only slightly longer, and slower than testosterone propionate, and can be used interchangeably.

Steroid Form

Testosterone hexahydrobenzoate is no longer available as an independent commercial drug product. The Sterandryl Retard brand comes in an oil solution for intramuscular injection, and is typically found in 1 or 2 ml glass ampules dosed at 50, 100, or 125 mg/ml.


Indications/Purpose & Side Effects

Additional Information

Testosterone should be the base of any multi-compound anabolic steroid cycle because it supports the body's physiological functioning during the administration of exogenous male sex hormones. Sterandryl Retard is a highly effective bulking cycle anabolic that's generally combined with such legendary ingredients as Trenbolone, Dianabol, Deca-Durabolin, and Equipoise. Sterandryl Retard provides the same support when added to cutting cycles, which are often comprised of potent definition promoting compounds like Oxandrolone, Oral Turinabol, and Winstrol.
