1. Know If TRT Is Working
Total testosterone alone doesn't tell you much. Free testosterone and SHBG determine how much is actually available to your body, so tracking all three shows whether your dose is doing its job.

2. Keep Estrogen In Check
Testosterone converts to estradiol in your body. When the two drift out of balance it shows up as mood swings, low energy, and slow recovery, so the ratio matters as much as the levels.

3. Find What's Draining Your Energy
Testosterone isn't the only thing driving how you feel. Ferritin, vitamin D, and albumin all shape recovery and energy, and one low marker can hold you back even when your hormones look optimized.

4. Stay Ahead of Heart Risk
Hormone therapy can shift your lipids over time. ApoB, LDL, HDL, and hs-CRP show whether TRT is moving your cardiovascular risk, long before you'd feel anything.

5. See the Full Picture
TRT changes more than testosterone. Metabolism, inflammation, and organ function all adapt, so tracking markers like creatinine month to month shows how your whole body is responding.

Great for tracking biomarkers
I have felt off for a while, but never could pin point the issue. I’m on TRT and have blood work every 3-6 months; however, ferritin is one that was never tested. Mine came back low and now it all makes sense.

Recently started TRT. Adding these monthly labs from Rythm in conjunction with the semi annual labs w/ my doc will make dialing in my dose so much easier. The home test kits are super convenient, and the lab work is extremely comprehensive. Anyone taking hormones and peptides should absolutely add Rythm testing to their protocol.

Frequently Asked Questions
How is Rythm different?
Most blood testing companies charge $500 or more for a single test per biomarker, providing only a one-time snapshot that doesn’t capture your long-term health trends or reflect your true baseline. This approach can lead to missed patterns or even misdiagnoses due to limited data. Rythm takes a different approach, using monthly tracking to build a detailed picture of your health over time. This allows for more accurate insights, better optimization, and a clearer understanding of how your body is evolving.
Does Rythm help me improve?
Rythm provides actionable suggestions and tips to help you optimize each biomarker
Is Rythm HIPAA compliant?
Yes, Rythm is HIPAA compliant. Your data is securely stored and handled in accordance with strict privacy and security standards.
Can I cancel anytime without fees?
Yes, you can cancel anytime without any fees.
Does Rythm accept HSA/FSA payments?
Yes, Rythm is HSA/FSA eligible. You can use your HSA or FSA card at checkout or submit your Rythm receipt to your provider for reimbursement.
How long does it take to get my results?
You will receive your results within 3 business days – as long as it's returned within 7 days of receiving your kit. Delays can occur if you do not send your sample back in time.
