i used it and di eod day inject with good results i would not go less then that
i would even consider ed injects to keep levels more stable
i liked npp alot although i have never used regular deca so i cannot compare
i liked the fact that it is fast acting and thought it would be a good idea to start with that incase i got some bad side effects i could stop and it would clear my system fairly qucikly as compared to regular deca
hope this helps man enjoy
