BM Pharmaceuticals lists this one as Prominate: methenolone enanthate at 100 mg/ml, boxed as ten glass ampoules of a millilitre each. BM is an Indian house with a long catalogue of ampoule-based injectables, and that format is what the brand is most associated with.
Methenolone sits apart from most injectable androgens because it descends from dihydrotestosterone rather than testosterone. It has no route to oestrogen through aromatase and its androgenic activity is on the modest side, which is why it comes up so regularly in discussions of lower-key injectable compounds.
