Nandrolone Phenylpropionate is a short form of “deki” – colloquially known as “short cup”, “super”. It is a short-ester Nandrolone, which, like other Nandrolones, is characterized by a high anabolic index with a low androgenic index at the same time.
It is, next to Deca-Durabolin, one of the safest and most popular injectables used in bodybuilding to increase good-quality muscle mass and strength.
Its mechanism of action is similar to that of Nandrolone Decanoat, but in practice it gives a more “dry” muscle. As it is a short ester – it aromatizes to a lesser extent – therefore water retention is lower than in the case of Nandrolone Decanoat.
It can be noticed only at higher doses, although it is not as strong as in the case of using, for example, Testosterone, as Nandrolone Decanoat aromatizes to a less active norestrogen in a small percentage.
Similarly, converting to DHT – in the case of Nandrolone, it converts to NORDHT, which is not as strong as its testosterone counterpart, so the side effects from DHT are smaller.
Another advantage of the “short cup” over “deca” is the fact that the cycle can last 6 weeks – and you can get good gains during this time – especially when combined with other measures. Competitors most often combine it with Testosterone propionate, Metanabol and Winstrol.
