I mostly used Ainterol X-R1 Atomizer. This is supposedly the most advanced and powerful spray of the three Ainterol makes. You can order on line from a couple of different Ainterol sites. My last bottle was shipped from Thailand.
Because it is a spray, it is absorbed through the skin. Tablets have to be processed by your internal organs. Supposedly sprays, or liquids placed under the tongue, are easier on your vital organs. One vital organ however is affected regardless of tablet or spray--yes the below the waist organ which will lose its vitality.
If you used a spray, it is very important to massage your breasts. 10-15 minutes if possible because this helps the PM get into your blood circulation. I know it is a nuisance having to massage your soft breasts (LOL), but do it anyway. There are various massage techniques. Look on YouTube, etc.
