Testosterone replacement therapy at Circle
Safe and supervised TRT has long-term benefits for sexual function, bone density, and muscle mass—especially with consistent monitoring to protect your fertility and prostate.
The markers we monitor
We look at all the markers that influence your testosterone levels. You review your results with a Circle physician so you know exactly what they mean, what you need to work on, and why.
Confirmed on 2 morning draws
Why we test it
One low test means nothing because levels swing daily. Two morning draws tell us what's really happening.
The 'why' signals
Why we test it
By understanding the root of the problem, we can effectively tailor treatment.
The usable fraction
Why we test it
This confirms if the shortage is real and not a lab error.
Hormone balance
Why we test it
Healthy Estradiol levels should be maintained, not eliminated like the forums suggest.
Blood health · safety
Why we test it
Treatment can raise this. We get a baseline and re-check on schedule to ensure optimal levels.
Prostate safety
Why we test it
We always get a baseline and monitor throughout treatment to keep the prostate safe.
