In one week, weight increase of 4 kg needs medical attention. Please consult a good doctor.
Also Cosmic Serums will take time to work, and its not due to Cosmic Serums that weight would increase. You can continue with VK healing anyways.
Check your eating habits, the weight building might be happening earlier also. But maybe now you are correlating it with VK healing.
Also check your emotional status. Many people tend to eat and sleep more with emotional stress. May be you need to take Cosmic serums for your emotional healing too.
Find out the cause of this weight gain ……and treat that cause too.
GOLDEN SUNRISE to your healing !!
