Safety first
What to know before starting online TRT
Testosterone replacement therapy is a prescription, federally controlled medicationwith real effects on your blood, heart and fertility. Done right — with proper labs and monitoring — it's safe for most men. Here's what a responsible program looks like.
Safety resources
Testosterone side effects
Acne, fluid retention, mood changes, and elevated red blood cell count (hematocrit). What's normal vs what needs a doctor.
Bloodwork you actually need
Total & free testosterone, estradiol, hematocrit/CBC, PSA, and lipids — and how often a good clinic re-tests.
Hematocrit & blood thickness
TRT can raise red blood cell count; untreated, it raises clot risk. Why monitoring matters more than the dose.
Estrogen (estradiol) management
When an aromatase inhibitor is and isn't appropriate, and why over-suppressing estrogen backfires.
Fertility & TRT
TRT can suppress sperm production. Options like hCG or enclomiphene that preserve fertility.
Is it a controlled substance?
Testosterone is federally controlled. What that means for telehealth prescribing and the 2026 DEA flexibilities.
Essential safety checklist
Verify the clinic uses licensed physicians
A legitimate online clinic requires bloodwork and has a licensed clinician review your labs — never a questionnaire-only prescription.
Insist on baseline + follow-up labs
If a provider skips bloodwork, walk away. Monitoring (hematocrit, PSA, estradiol) is what keeps TRT safe.
Report side effects to FDA MedWatch
Serious adverse events can be reported at fda.gov/medwatch — and tell your prescriber immediately.
