Product description

Our smaller GcMAF sublingual spray option - 35 days supply (used twice a day)

Total GcMAF per bottle: 20,000ng
GcMAF per individual spray: 286ng
Sprays per bottle: 70 (lasts for 35 days used twice a day)

This is simply a smaller version of our top-selling 50,000ng 25ml spray. It contains exactly the same 286ng of active bioidentical GcMAF per spray, however there are only 70 applications instead of 175 per bottle. The formula is sprayed directly under the tongue where it is absorbed through the tissue into the bloodstream for distribution throughout localized and connected macrophage pools. There are no additional ingredients in this spray except the natural saline solution which the GcMAF is suspended in, thus making it an all-natural solution.

The recommended daily dose is 1 spray twice a day for more aggressive issues, or 1 spray once per day for less aggressive purposes or general maintenance. For best results spray under the tongue at least 15 minutes before/after eating or drinking.


  • GcMAF
  • Saline (sterile salt water)

Sublingual application

To use, simply spray under the back of the tongue twice a day. The liquid formula is designed to be absorbed into the capillaries under the thin layers of tongue tissue and distributed throughout the broader blood/circulatory systems. This is a very effective way for the GcMAF to activate monocytes (macrophages in the blood) as well as those located in connected tissues/organs, into a phagocytic state. The spray is not designed to be digested. We recommend not eating for 15 minutes before after use so that is not attached to food/liquid particles and digested. If GcMAF is digested the stomach acids will break it down, thus rendering it useless. This is why we DO NOT recommend using any type of GcMAF product which is digested including tablets, lollies or yogurts regardless of what the manufacturer says about enteric coatings or the like. These are simply ineffective.

Product instructions


Spray once directly under the tongue, holding it there so the liquid is fully absorbed. For more serious issues do this twice a day, morning and evening. For minor issues and general immune maintenance, one spray per day is sufficient. For very aggressive issues you may use 3 sprays per day, or back this up by also using one of the transdermal creams available in our packs. Do not consume any solids or liquids for at least 15 minutes before and after administering.
