Sustarow by Crowx Labs supplies testosterone propionate, testosterone phenylpropionate, testosterone isocaproate and testosterone decanoate in one 10 ml vial, each millilitre labelled at 300 mg total. The four esters are combined in injectable form, and the vial is sealed for multiple draws.

Testosterone Ester Breakdown in the Sustarow Label

The label names propionate, phenylpropionate, isocaproate and decanoate as the four testosterone esters present. Each contributes to the 300 mg per ml concentration printed on the vial. Where single-ester products such as Superbull or sustanon 250 injection carry one compound, this blend distributes the total across four. The company behind the label, Crowx Labs, has been based in the USA since 2020.

300 mg per ml Concentration in a 10 ml Vial

Each vial holds 10 ml at 300 mg per ml, giving 3,000 mg total testosterone across the four esters. That concentration sits above the 250 mg per ml common to many blends carrying the same ester combination. The vial format allows for measured draws with a syringe, and the rubber stopper reseals after each puncture.
