Frequently Asked

FAQ / Safety / Q03

How often do I meet with a clinician or provide blood samples?

You will receive Wellcore’s practically painless at-home blood collection device about eight weeks after starting your personalized treatment protocol. After your blood sample has been analyzed by our lab, a member of your Client Success Team will contact you to schedule a follow-up to review your results and discuss any further optimizations. It is important that you complete this follow-up process in a timely manner to avoid any delays in refilling your medication(s).

FAQ / Safety / Q03

Will Wellcore function as my primary care physician (PCP)?

No, you should still have a PCP to address any acute issues or concerns. We will alert you if we believe you need to follow-up with your PCP for any abnormalities that we see in your bloodwork or medical history that may require further investigation.

FAQ / Safety / Q03

What happens during and after my Wellcore clinician consultation?

Your Wellcore clinician will discuss your medical history, bloodwork and current concerns and determine whether a personalized treatment protocol is a good fit for you. If medications are recommended, you will have the option to pay for and begin treatment immediately.

FAQ / Safety / Q03

What makes Wellcore different from other companies that provide access to testosterone-boosting therapies?

Wellcore’s top priority is providing safe and effective hormone optimization therapy to our clients. We achieve this by continually monitoring up to two dozen different biomarkers with a convenient, practically painless, at-home, whole-blood-collection device called Tasso. These biomarkers consist of all seven sex hormones related to testosterone therapy, including free testosterone. Free testosterone is the most important analyte to monitor while on testosterone optimization therapy because it is the unbound, active form of testosterone that creates the physiological benefits of increasing one’s testosterone levels. Most companies monitor one’s total testosterone level. Wellcore also assesses cholesterol levels, kidney function, liver function and the percentage of red blood cells circulating in your blood (hematocrit). Hematocrit is important for safety because being on hormone optimization therapy for more than three months can raise one’s production of red blood cells. This can be a good thing, as it increases the oxygen-carrying capacity of your body, but it can also increase blood pressure. Wellcore uses a practically painless auto-injector device to administer testosterone injections. These injections allow us to use a smaller, shorter needle. With the reusable auto-injector device, one doesn’t have to self-jab with a needle. The device does all the work at the push of a button.

FAQ / Safety / Q03

What are some of the benefits of Wellcore’s Hormone Optimization Therapy service for men?

Potential benefits include an increase in strength, fat loss, muscle mass, bone density, sex drive, sexual function, mood and exercise recovery. Studies demonstrate a reduced risk of diabetes, osteoporosis and overall metabolic health (glucose, triglycerides, cholesterol) after 1 year of continuous therapy. Hormone optimization therapy IS NOT a magic elixir. The more you improve your sleep, nutrition and exercise regimen while on hormone optimization therapy, the better your results and overall risk of developing chronic diseases in the future will be.
