Ultima Pharmaceuticals supplies Enan 250 as a 10 ml vial of injectable Testosterone Enanthate solution, with each millilitre carrying 250 mg of the hormone. The enanthate ester distinguishes this formulation from propionate, cypionate and other testosterone variants that differ in release profile and injection scheduling, making ester identification essential when planning a test npp primo cycle or comparing one product against another.

250 mg/ml Testosterone Enanthate in a Multi-Dose Vial

The concentration sits between lighter-dosed options and higher-strength preparations: testosterone enanthate 250 mg/ml vial formats from Gomeisa Labs match this strength, while Beligas Pharma's testosterone enanthate 300mg vial pushes the dose higher and Ultima's own Enan 400 raises it further still. The 10 ml format provides multiple draws from a single sealed container. Ultima Pharmaceuticals, based in the USA and producing these since 2022, uses this vial design across its testosterone enanthate line.

Enanthate at 250 mg Beside Other Labs' Offerings

Xeno Labs, Crowx Labs and Ryzen Pharmaceuticals each list a 250 mg per ml enanthate vial at the same volume, so the choice between them turns on label preference and batch reputation rather than on specification gaps. Driada Medical's Testos 250Mg and Sixpex's Testopex E share the strength and pack format, while Bull Pharma's Fortebull holds the same 10 ml volume. The enanthate ester itself is common to all these products; what separates one from another is the maker's name on the label and the lot consistency buyers report.
