I am on 160 mg of test a week split into 2 doses. Since starting i feel like my voice has been changing, I am in a band that sings alot classic rock and certain notes are getting harder to hit. I am in the 3rd month and it could just be me but I feel like it is even harder now. Is voice deepening to the point where it can affect vocals normal? If it is, is there a way to halt this effect? Or if I stop trt will my voice revert back?

Great question — and a really important one for anyone using their voice professionally.

Voice changes like deepening are typically associated with the effects of testosterone during puberty, but for adult men starting TRT, the changes are usually subtler. That said, some users do report minor shifts in vocal quality — especially in the early months — due to factors like:

• Slight thickening of the vocal cords (rare, but possible)
• Changes in fluid retention or inflammation that affect resonance or vocal range
• Shifts in energy or mood that might alter how you project or control your voice

However, it’s not typical for TRT to cause major or permanent vocal deepening in adults. If you're noticing a drop in your upper range, especially as a singer, it's worth also looking into:

• Estradiol levels — Too low or too high can affect vocal fold flexibility.
• Thyroid function — TRT can impact it, and thyroid imbalances can affect voice.
• Hydration and inflammation — Testosterone can affect water balance and sinus/congestion issues in some users.

What you can do:

• Ask your provider to run a full panel (total T, free T, E2, SHBG, thyroid panel).
• Stay well-hydrated, warm up your voice regularly, and monitor your vocal performance.
• You might also consider trialing a slightly lower dose if your levels are above optimal, especially if you're highly sensitive to testosterone's effects.

If you were to stop TRT, your voice may gradually return to baseline over time — but this isn't guaranteed, and any changes that did occur structurally (though unlikely) might not fully reverse.

Bottom line: Voice changes aren’t common, but they can happen. The key is dialing in your protocol and checking the bigger hormonal picture — and of course, working closely with your provider to protect what matters most to you.
