Bioidentical testosterone is an exact replica of the hormones that are naturally produced by the body. Bioidentical testosterone are based on compounds found in plants like yams or soy beans. The plant-based hormone is processed in such a way that its structure is identical to hormones produced naturally by your body. This is why Bioidentical testosterone are termed “natural” and our bodies can metabolize them. These hormones come in various forms including tablets, under the skin pellets, creams, gels, and nasal sprays.
