This is an injectable combination of medication of 4 different testosterone esters all of which are androgenic anabolic steroids (AAS). This product contains: 30 mg of propionate, 60 mg of phenylpropionate and 60 mg of isocaproate and also 100 mg of testosterone decanoate making the total of 250 mg – hence the name. They are all offering the exact same hormone – Testosterone, so why they had to blend them? Every ester is having different time release when is being administered.
With this being said, every form of testosterone is released in the body at different times. Using a combination of 4 – you receive testosterone very quickly thanks to short acting testosterone esters but in the same time you have a prolonged release thanks to long acting esters
