When 2 serums are to be used for the healing of 2 problems then we don't add them in one request
For example if someone has heart problem and kidney problem so the healing will be done separately
Also any health serums are not combined with TOTAL WEALTH SERUM AND LOVE SERUM
Maximum 5 energies related to one healing in one request or for one bottle if you are charging water
For your first question I understand that your professor is strict and you have to give presentation
If that's the case send GOLDEN SUNRISE and LOVE SERUM TO YOUR PROFESSOR
Also send the combination of GOLDEN SUNRISE, BEAUTY SERUM to your presentation and your speech
Also take GOLDEN SUNRISE,ALPHA MALE SERUM, BEAUTY SERUM,BALANCE SERUM ,ENERGY OF SUCCESS for yourself
You can also send Love serum to universe
