Here’s what consumers have asked with answers from RealSpellCasting staff and previous consumers.
Yes will be after the 4 full moon cycle you will see the results, however you don't count the month that your spell was cast has to be a full 4 months cycle.
I didn't buy their single spell, however i did buy their triple spell and it took over 4 months like they told me it would. I am just questing but i would say that it would be the same for their single spell as well. If they had told you 12 months that most of their clients had seen results then it may take that long.
