Trenbolone Acetate and Enanthate are basically the same things, the only difference being their half-lives. Acetate has a much shorter half-life when compared to Enanthate and therefore works quicker and is out the system quicker.
Often referred to as Tren Ace or Tren-A has a half-life of around 48 hours, due to its short half-life Tren Ace needs to be injected a minimum of every second day. Most people choose to use Tren Ace in cutting cycles accompanied with other fast acting steroids such as Testosterone Propionate and Winstrol. Trenbolone acetate usually comes in 10ml vials dosed between 80 and 100mg/ml. Due to the many harsh side effects that come with using Trenbolone, many users choose to use the Acetate version so that they can discontinue use if needed and within a few days the side effects will start disappearing.
Also known as Tren E or Tren Enan, Trenbolone Acetate has a half-life of around 7 to 10 days and only needs to be injected once or twice a week. Tren E is mainly used in bulking cycles with other long-acting steroids such as Testosterone Cypionate or Enanthate. Tren E is generally sold in 10ml vials dosed at 150 to 200mg/ml.
