Frequently Asked Questions
What testosterone levels qualify for TRT?
There is no single threshold. Most guidelines consider total testosterone below 300 ng/dL as potentially low, but diagnosis also depends on symptoms, free testosterone levels, and clinical context. Your provider will evaluate the full picture.
How long does TRT take to work?
Many patients report improvements in energy and mood within 2-4 weeks. Changes in body composition, libido, and cognitive function typically develop over 3-6 months. Individual timelines vary based on starting levels and protocol.
Does TRT cause hair loss?
TRT may accelerate hair loss in men who are genetically predisposed to androgenetic alopecia. Your provider can discuss risk factors and potential mitigation strategies during your consultation.
Can I stop TRT once I start?
Yes, TRT can be discontinued. However, testosterone levels will typically return to pre-treatment baseline. Your provider will discuss tapering strategies and what to expect if you choose to stop.
Is TRT covered by insurance?
Bloom Metabolics operates as a cash-pay telehealth clinic with transparent pricing. This eliminates insurance billing complexity and prior authorization delays. Many patients find this more convenient and predictable.
