(TES-tos-ter-own en-AN-thate)
Testosterone enanthate is testosterone bound to the enanthate ester, which releases testosterone into your bloodstream over roughly seven to ten days. It is nearly identical to testosterone cypionate in clinical effect—same dosing schedules, same stable levels, same labs—and your physician may choose one or the other based on availability, personal preference, or your prior experience. Like cypionate, it is formulated here in grapeseed-free MCT oil, compounded by a licensed pharmacy, and injected weekly or as your physician prescribes.
Interchangeable
enanthate and cypionate release testosterone at a similar rate; the choice between them is practical, not about results
The difference from cypionate is clinically small. If you've used one ester successfully, the other works similarly. Your physician decides which fits your plan.
Men who want weekly enanthate under the skin in MCT oil.
Enanthate is the ester in the FDA-approved under-the-skin auto-injector; this is the compounded vial.

Day 1
A US-licensed physician reviews your symptoms, testosterone level, health history, risk factors and labs (testosterone, hematocrit, PSA, estradiol, lipids), and sets your dose and formulation. Your treatment ships discreetly to your door.
1Weeks 1–4
You begin your chosen formulation (injection, cream, or troche). Energy, mood, and libido often begin to shift. Your physician checks in by messaging.
2Month 2
Lab work (usually testosterone level and hematocrit) is drawn. Your physician reviews your symptoms and adjusts the dose if needed. Most men reach stable levels by month 2–3.
3Month 3
Full check-in. Your physician reviews all labs, how you feel, side effects and whether your dose is right. If acne or mood changes appear, they are usually managed by dose adjustment.
4Ongoing
Testosterone therapy continues as long as it benefits you. Labs (testosterone, hematocrit, PSA, lipids) are checked at least every 6–12 months. Your physician adjusts the dose with you over time.
5Individual results vary. Benefits reflect what Zepym Health members commonly report to their physician at check-ins; they are not the results of a clinical trial.
This is the starting dose the pharmacy prints on the label. Your physician sets yours and adjusts it with you.

Testosterone enanthate and cypionate are the most commonly prescribed testosterone esters in testosterone replacement therapy, with similar pharmacokinetics and clinical outcomes. The choice between them is often based on practical preference rather than efficacy differences.
Long-acting esters like enanthate provide stable serum testosterone levels that reduce the frequency of clinic visits and allow for straightforward self-injection protocols established with your physician.
Learn moreTestosterone is a prescription hormone for symptomatic hypogonadism in men without contraindications. Common, usually temporary side effects include acne, oily skin, hair loss (or growth on the body and face), changes in mood or libido, injection-site redness or soreness, and testicular shrinkage (reversible with gonadorelin or hCG). Testosterone increases hematocrit (red blood cell concentration), which can thicken the blood and raise clot risk; your physician monitors this with lab tests and may adjust dose or suggest blood donation if hematocrit rises too high. It can worsen sleep apnea, raise blood pressure slightly, and affect cholesterol levels. Testosterone is not prescribed with a history of prostate or breast cancer, untreated or severe sleep apnea, recent heart attack or stroke, uncontrolled high blood pressure, or abnormally high hematocrit. Testosterone therapy suppresses sperm production (reversible with gonadorelin or hCG if you want to preserve fertility). If you have a partner who could be pregnant, avoid transfer of topical testosterone by washing hands thoroughly and covering the application site. Seek care immediately for chest pain, shortness of breath, unusual leg swelling, severe headache or vision changes. Tell your physician about every medication and supplement you take.

Yes. The law requires a live video visit with the physician before it can be prescribed.
Nearly identical. Both are long-acting esters that peak at about the same time and create stable levels over roughly seven to ten days. Cypionate is slightly shorter-acting; enanthate slightly longer. Clinical effects are the same, and your physician may choose either based on what works for you or what is available.
Not necessarily. Gonadorelin or hCG are used if you want to preserve sperm production and testicular size while on testosterone therapy. Without them, the testes will shrink slightly and sperm production will stop—effects that reverse if you stop testosterone. Your physician discusses your priorities.
At baseline and regularly (every 6–12 months): testosterone level, hematocrit (to check for polycythemia), PSA (to screen for prostate concerns), estradiol (some testosterone converts to estrogen), and lipids (cholesterol and triglycerides). Your physician explains what the results mean and adjusts your dose based on them.
Yes. Testosterone therapy is not a lifetime commitment; you can pause or stop. If you stop suddenly, testosterone levels will fall over days to weeks (depending on formulation) and you may feel the original hypogonadism symptoms return. Your physician helps you taper if you choose, and many men simply stop and restart later if they need to.
