Hi @Nena!
You’re welcome.
That looks like a very nice stack. Joint Regeneration is the most important audio to help with the recovery of the cartilage in the knee, I believe. It can be listened to as much as needed. I would suggest adding The Super Human Mutant (every 12hrs) x2. It helps with regeneration. I would also add Enhanced Cellular Nutrient Absorption (30 mins after main meal) x2, to speed up healing. For now, I would suggest just sticking with all these audios and see how you go.
If you would like to speed up recovery even further, I would suggest getting the Advanced Healing Dog Tag. Please read this post before you decide to get this Dog Tag.
Optionally, other audios that may help with knee repair, listed in suggested order of importance and effectiveness:
Experimental Arthritis Treatment
HGH release version 2.0 (Gumroad)
Hyperbaric Oxygen Therapy
Collagen Booster
Automated Calves and Feet Workout with Joint Strengthening
After Workout Muscle Recovery
Chi Compression into Bone Marrow
Bone and Organ Breathing
Senescent Cell Removal
I would also ask Dreamweaver or sammyg to see what their suggestions are. You can contact them here.
