Test P 100 by Xeno Labs delivers testosterone propionate at 100 mg per ml in a 10 ml vial for injection. The propionate ester distinguishes this label from longer-acting blends listed alongside it, and the concentration sits below the 200 mg offerings from competing labs in the same category. Xeno Labs, a USA-based company making these since 2018, prints the substance name, ester and strength on every vial.

Testosterone Propionate at 100 mg per Milliliter

The 100 mg dosage per ml gives ten milliliters of injectable solution per vial, a total matched by most propionate listings but at varied strengths. Where another lab bottles propionate at 200 mg/ml in the same volume, you get double the active compound per draw; this formulation gives half that concentration, which matters when planning pin frequency and total volume. The propionate ester on the label is shorter-chained than enanthate or cypionate, a specification that changes nothing about the testosterone propionate price or packaging but differentiates this product within the broader testosterone category.

Vial Format Against Competing Propionate Packs

The 10 ml vial is Xeno Labs' standard container for this line, shared with their other testosterone preparations. Some labs ship propionate in 1 ml ampoules or smaller multi-dose vials; this format consolidates ten milliliters under one stopper. Comparing pack sizes across labs means checking whether a rival's lower per-unit cost reflects a smaller vial or a higher concentration — a 5 ml vial at 200 mg/ml holds the same total milligrams as this 10 ml format at half the strength, so count and concentration together determine what the testosterone propionate price represents.
