The sublinguals such as conolodine 1,nutra g1, and phytotest are very productive, and have nice taste ,and are all natural. I love the fact that although we are in a health crisist,treatment and preventative..... P.O. is allnatural... And safe.Synthesization is not good,like preservatives,chemicals.etc,and p.o. products do not contain any of these harmful ingredientsI fully recommend products to anyone who want relief or supplimetal boosts,..w/out the damaging side effects.
