Bull Pharma's Primobull delivers Methenolone Enanthate at 100 mg per ml in a single 10 ml vial. This injectable form carries the enanthate ester, distinguishing it from acetate variants that typically come as oral tablets or shorter-ester injections. The vial format offers a measured volume for those who prefer to buy Primobolan injections online in the US and track their supply across multiple applications. Bull Pharma, based in the USA, has manufactured this line since 2022.

100 mg/ml Methenolone Enanthate in a 10 ml Vial

The 100 mg concentration sits below the 200 mg options from other labs, meaning each milliliter holds half the active substance. A vial at this strength requires twice the volume to match the total content of a higher-dosed product. The 10 ml size is standard across primobolan, and the single-vial pack keeps the purchase straightforward without multi-unit bundles.

Primobull Against Xeno Labs Primo 100

Xeno Labs also lists Methenolone Enanthate at 100 mg per ml in a 10 ml vial, making the two products identical in substance, ester, concentration and volume. The difference lies in the lab name on the label and the company behind it. Both are enanthate formulations, while acetate versions of the same compound typically appear as 25 mg tablets rather than multi-milliliter vials. Where a listing shows 200 mg per ml, the vial holds twice the methenolone per milliliter but the same 10 ml total volume.
