  CHK Nutrition sells monoamine support products to clinics. We do not deal with or give advice to anyone who does not have a medical license. These products include NeuroReplete, RepleteExtra, D5, D5 Extra, TyrosineReplete, 40% Mucuna, 5-HTP, and CysReplete.

  CHK Nutrition started by selling 5-HTP tyrosine, and L-dopa (mucuna source, not faba bean source) formulas to medical clinics who were having trouble finding consistent quality in the products they were buying in local stores. In some cases 90% of the 5-HTP products bought in local stores did not live up to clinical expectations. In many cases the 5-HTP sold in stores has a little as 5% 5-HTP by weight.

  Other concerns that arose from clinics attempting to obtain properly balanced 5-HTP, tyrosine, and L-dopa (mucuna sourced, not faba bean sourced). The problem being if only 5-HTP or improperly balanced 5-HTP is given it will deplete of dopamine. On the other hand if only tyrosine and/or L-dopa is taken or improperly balanced tyrosine and/or L-dopa is taken it will deplete of serotonin.
