Generally speaking adding more subs doesn’t “reduce” results but in my opinion, it spreads them out.
You’re still developing in all areas, but you’re developing in more areas simultaneously, so you get the same amount of results, but in more areas therefore less results per area, but it all balances out if you listen to the stack for long enough.
I think listening to Dragon Reborn solo for 4 months, then Regeneration solo for 4 months, then LBFH solo for 4 months would get you approximately the same results as running all 3 for 12 months.
Sometimes subs with contrary goals can make taking action more difficult… running Wanted Black and Emperor Black means you’re not going to take 100% of the action needed on most of the scripting from both. That’s an example of where it’d be better to run them separately - so you can take action on both.
Meanwhile, running Wanted Black with S&SX, or running Emperor with Limitless Executive… random examples… both of those stacks would help you take MORE action, therefore get more results.
Action is the key in both cases. Even with healing, you have to take action, socially, personally, professionally, and of course emotionally actually doing healing work where possible.
So for me, rather than three healing subs, I’d suggest stacking a healing sub with a sub that’s related to your future goals. Healing will dominate the stack anyways. But it’s just a good anchor. Are you “healing” so you can show up more fully when you interact? Stack something with Ascension or whatever you want to express socially. Want to heal your masculinity? GLM. Want to pursue financial goals but are stuck by anxiety? Healing + Mogul. Want to heal so you can develop a relationship? Healing + Wanted
Chosen is an alpha sub that heals with general positivity, instead of “healing” directly. It would be very good to stack with any healing sub.
And the original Love Bomb has the same premise, so it has light healing but also just makes people really nice to you which is an amazing healing experience by itself.
Could do Healing + Chosen + Goal oriented sub
