A Zapper with one frequency and positive square wave will kill a whole array of critters regardless of their frequency. You only have to worry about the critters frequency when dealing with RIFE style attacks.
I wouldn't entertain buying any 30Khz zapper as the penetration has been proven to be lame. I would go for a Terminator over all of them products including the MiniFG. The MiniFG is more technical and advanced in electronics. I won't entertain doing Rife style frequency work without a DIRP function on a FSCAN. I don't want to guess especially when parasite
frequencies change so easily per person which has been proven.
I would suggest if you suffer Hypothyroidism then check your water supply for Fluoride or any other intake of this substance you may have. It actually resides in the thyroid! They used Fluoride to bring down figures of HYPER so imagine what its doing to normal level thyroids.
I would suggest Pharmalogical dosage Vitamin C which will help with the adrenals and alot of your problems. You must drink the correct amount of water a day as im quite sure you will not only be subclinically scurvy as in the above but subclinically de-hydrated. You'd be amazed what results you can get from taking large vitamin c dosages and drinking the correct amount of water a day. Study on Dr.F.Batmanghelidj for water and Linus Pauling, Klenner, Irwin Stone, Steve Hinckley on Vitamin C. Also make sure your sodium levels are correct as this makes a difference to! For every 8-10 glasses of water you need half a teaspoon of salt. This can be gotten through most processed foods but if your careful what you eat then you will not get enough salt normally like I didn't. If you end up using Vitaliser Plus water and dont take salt you will get sodium loss dramaticaly because of its shear hydrating power so therefore you should edge on caution and take the salt after 4-5 glasses with that style water (Hexagonal)
You could also try M.S.M to help with your hair and it works synergistically with Vitamin C too.
