TRT Side Effects FAQ
5 questions answered about side effects for testosterone replacement therapy.
What are the side effects of TRT?
Common TRT side effects include acne (20-40%), elevated hematocrit (15-25%), testicular atrophy (50-70% without HCG), mood fluctuations (15-30%), water retention (10-20%), and hair changes (10-25% with genetic predisposition). Most side effects are manageable with proper monitoring and protocol adjustments.
Does TRT cause hair loss?
TRT can accelerate hair loss in men genetically predisposed to male pattern baldness. Testosterone converts to DHT, which miniaturizes hair follicles. However, TRT does not cause hair loss in men without the genetic predisposition. Finasteride or dutasteride can block DHT conversion to mitigate this effect.
Does TRT cause acne?
Yes, acne is a common side effect of TRT, affecting 20-40% of patients. It is caused by increased sebum production from elevated androgens. Acne typically improves within 3-6 months as the body adjusts. Managing estrogen levels, maintaining hygiene, and using benzoyl peroxide can help.
How do I prevent hair loss on TRT?
To prevent hair loss on TRT, consider low-dose finasteride (1mg/day) to block DHT conversion, topical minoxidil twice daily, ketoconazole shampoo 2-3 times per week, and micro-needling. Lowering your TRT dose may also slow hair loss. Discuss options with your provider before starting any DHT blockers.
How do I manage acne on TRT?
Manage TRT acne with twice-daily cleansing using benzoyl peroxide or salicylic acid, non-comedogenic moisturizer, and estrogen management (high E2 worsens acne). More frequent injections provide more stable hormone levels. For severe acne, your provider may prescribe low-dose isotretinoin.
