If I were trying to frontload an anabolic androgenic steroids I would find the shorter ester version and combine with the long esther. For example, If you do NPP - Nandrolone PhenylPropionate - for the first week and then Deca-Durabolin - nandrolone decanoate - the second week on it will still take a while for the Deca ester to release. I think that the more thought out method would be to do Deca-Durabolin - nandrolone decanoate - from the beginning. But, add NPP in order to more quickly get your blood levels right. Thats why my next cycle will use trenbolone E and A in the first week. As well as testosterone propionate and testosterone cypionate. After the first week or two I will drop the short acting ester.
