I have been using subs for a little more than 1,5 years. The main I have used are Khan, Dragon Reborn, Love Bomb, and Alchemist. I went from a major existential crisis in my life to having healed a lot of my old traumas that used to hold me back, of course not in every area, and there are a lot of different programs that covers a lot of things.
Listen to @RVconsultant advise below and start off with one program in the beginning, and Ascension is a great first pick IMO. Healing is needed to be able to grow and it’s very easy to be inpatient and rush to other programs. You wouldn’t want to build your house without a stable foundation to build it on.
And keep a journal where you write down what is going on as you are listening, because it’s hard sometime to really be aware of them because you normalize your the new behaviors, but when you go back and re-read you can see just how much you have changed. Look for things that did not happen before listening to subliminals and trust the process. And lastly, read the official documents from SubClub on the support page.
