About Testosterone

These products replace testosterone, which drives male sexual development. The labels approve them for males with primary hypogonadism (testicular failure) or hypogonadotropic hypogonadism (pituitary or hypothalamic disease), most only in adults, and say safety and effectiveness in age-related low testosterone have not been established; use for low energy or aging without such a diagnosis is not FDA-approved, and the prescriber decides. The enanthate injection and Testopel are also labeled for selected boys with delayed puberty, and enanthate for some women with metastatic breast cancer. Low testosterone is confirmed by morning blood tests on at least two separate days, and doses follow blood levels: cypionate or enanthate 50 to 400 mg into the buttock muscle every 2 to 4 weeks, or Xyosted 75 mg under the skin weekly.

Skin gels and the underarm solution carry a boxed warning: virilization has been reported in children exposed to treated skin, so children must avoid unwashed or unclothed application sites, and the warnings add that women should too. Aveed’s boxed warning covers pulmonary oil microembolism reactions and anaphylaxis after any injection; it is available only through a REMS program, with 30 minutes of observation after each dose. In July 2025 the FDA approved labels that removed the blood pressure boxed warnings from Xyosted, Jatenzo, Tlando and Kyzatrex, but the labels still warn that testosterone can raise blood pressure. Other warnings cover a high red blood cell count, blood clots, worsening of an enlarged prostate and possible prostate cancer risk, swelling, sleep apnea, reduced sperm production, liver problems and abuse. It must not be used in pregnancy or by men with breast cancer or known or suspected prostate cancer.

As a Schedule III drug, a prescription can be refilled up to five times within six months of the date written; refill information can move between pharmacies only once unless they share a real-time online database, and an unfilled electronic prescription can be transferred once at the patient’s request where state law allows. Testosterone levels, hematocrit and blood pressure are checked during treatment, and the Tlando and Kyzatrex labels say neither can be substituted for other oral testosterone undecanoate products. Testopel pellets are implanted under the skin by a clinician every 3 to 6 months. The Androderm patch, Fortesta gel, Axiron solution and Delatestryl injection are discontinued.

Taking Testosterone

How to take it

Apply gels and the solution once a day in the morning, to clean, dry, intact skin where your label says, never the genitals; let it dry, cover it, wash your hands, and wait before showering or swimming as your label directs. Take capsules twice a day with food; Natesto is one pump in each nostril three times a day.

If you miss a dose

For a gel, solution or capsule, use the missed dose when you remember unless the next is nearly due, and never double up. For injections, ask the prescriber or pharmacist.

Storage

At room temperature, out of reach of children; gels and the solution are flammable until dry. Keep Xyosted in its carton, not refrigerated or frozen, and put used autoinjectors and needles in a sharps container.

Interactions to know about

Testosterone can lower blood sugar and insulin needs and change the effect of warfarin, so INR is checked more often; corticosteroids add to fluid retention. Natesto is not recommended with nasal medicines other than decongestants such as oxymetazoline.

This summarizes the official prescribing information. Your prescriber’s and pharmacist’s instructions, and the leaflet that comes with your medicine, take priority.

Why the cash price for Testosterone differs from pharmacy to pharmacy

A pharmacist can substitute only a generic rated equivalent to the product prescribed. Generic 1 percent gels are rated in two groups, one against AndroGel and one against Testim, so a gel is swapped only within its group; AndroGel 1.62 percent gel has its own generics.

Xyosted, Aveed, Natesto, Testopel and the oral capsules have no rated generic, so every quote for them is for the brand. As a Schedule III drug, refill information can usually move to another pharmacy only once.

Ways to pay less for Testosterone without insurance

• Ask for a rated generic of the exact product prescribed, and check that the prescription does not block substitution.
• If a form with no generic is prescribed, ask the prescriber whether a generic form would suit you, or ask the maker whether a savings program applies to someone paying cash.
• Compare quotes before the first fill, since refill information can usually be transferred between pharmacies only once.
• Once your dose is stable, ask whether a ninety-day supply is allowed.
• Upload the prescription to Script Unlock so licensed pharmacies can quote their cash price. You pay the pharmacy directly.
