Primos by Driada Medical is labeled as Methenolone Enanthate in injection form, supplied in a single 10 ml vial with each ml holding 100 mg. The enanthate ester sets it apart from acetate-based primobolan steroid products that carry a different release profile and are typically found in oral or shorter-ester injectable formats. The vial format puts 1,000 mg of the substance across the full 10 ml, a baseline concentration common to several injectable anabolic steroids in this category but not universal—some labs label the same compound at 200 mg per ml in smaller volumes or primobolan 100mg/ml options in ampoule packs rather than vials.

Methenolone Enanthate in a Primobolan Ampoule versus Vial Pack

Where a primobolan injection ampoule holds a single-use sealed dose, this vial format allows multiple draws from the same container across a span of use. The 100 mg per ml dosage remains consistent with other enanthate-labeled products at this strength, though Xeno Labs offers the same concentration in a comparable vial while Gomeisa Labs lists compounds such as masteron 100 and nandrolone at 200 mg per ml in 10 ml vials for those comparing label strength across different substances. Driada Medical, an EU-based company making these since 2023, produces Primos under that specification without deviation from the stated 100 mg per ml mark.

10 ml Vial beside Other Injectable Pack Formats

The single 10 ml vial is standard for this product line, contrasting with multi-ampoule packs that divide the same total volume into pre-measured single-use units. A vial of this size and strength sits between the lower-dosed acetate forms and the higher-concentration enanthate products some labs run at double the mg per ml, meaning the total substance per container and the volume per injection both shift when comparing across those formats. The enanthate ester designation on the label is the key differentiator within Methenolone products, as acetate versions carry a distinct pharmacokinetic profile that guides their typical packaging and presentation.
