ZRT Testing is used to determine hormone and cortisol levels. Saliva, Urine & Blood Spot testing are available. Here are some tips for sample collection. When bioidentical hormones are acquired from a compounding pharmacy, a customized cocktail of hormones is prepared for each patient. These hormones can be acquired at a typical pharmacy in a variety of predetermined dosages. In both cases, prescriptions are determined by a set of tests conducted by a physician. Many bioidentical hormones are derived from soybeans and wild yams, which contain unique components that are chemically processed into identical reproductions of hormones produced by the body. In addition to being cost-effective, they can rapidly extract components and transform them into perfect duplicates of human hormones. Bioidentical hormones are administered through injection, cream, suppository, or orally. The compounding facility at Newberry Express Pharmacy is available to meet all of your BHRT needs.
