Spelled without the final e on the label, Dragon Pharma's Enanthat 250 is testosterone enanthate at 250 mg/ml in ten ampoules. The manufacturer is one of the larger producers in this segment and runs both ampoule and vial formats across its testosterone range; this is the ampoule side of that pair.
The ester is heptanoate, a chain long enough to keep the hormone releasing over an extended period once the oil settles in muscle. That slow profile is what separates it from short esters such as propionate, and it is the property the whole depot category is built on.
