Injectable testosterone is the most established way to run a replacement program. A US-licensed, DEA-registered clinician confirms low testosterone with bloodwork, prescribes cypionate or enanthate matched to your numbers, and monitors you as treatment continues. Compounded in the USA by licensed 503A pharmacies. No hidden overseas supply chain.

What it is

The most established form of testosterone replacement

Injectable testosterone uses an ester, usually cypionate or enanthate, suspended in a carrier oil. You or your clinician's protocol administer a small intramuscular or subcutaneous injection on a weekly or twice-weekly schedule, which keeps your levels steady between doses. It is the format with the longest track record for reaching and holding target testosterone.

Testosterone is a Schedule III controlled medication, so injections are prescribed only by a US-licensed, DEA-registered clinician and only after baseline labs confirm the need. Your medication is compounded in the USA by a licensed 503A pharmacy under your individual prescription. Compounded testosterone is not an FDA-approved drug, and the whole point of the program is the rigor around it: confirm with labs, prescribe when appropriate, and keep measuring.

How injections fit the program

Ester choice, dosing rhythm, and monitoring

01

Cypionate or enanthate

Your clinician selects the ester and the dose from your labs and history. Both cypionate and enanthate are long-acting testosterone esters; the difference is mostly in the fine detail of timing, which your prescriber manages.

02

A steady weekly rhythm

Most protocols split the weekly amount into one or two small injections to smooth out peaks and troughs. Compared with a single large dose, a weekly or twice-weekly rhythm tends to hold levels in a more even range.

03

Monitored with real labs

Injectable TRT is an ongoing clinical relationship. Your clinician runs follow-up labs every three to six months and tracks hematocrit, estradiol, PSA, and lipids, adjusting the ester, dose, or frequency as your numbers and symptoms evolve.

Sourcing and safety

A controlled medication, with a controlled process behind it.

From who writes the prescription to where the medication is compounded to what gets measured over time, the chain behind your injections is transparent by design.

DEA-registered prescriber

Testosterone is a DEA Schedule III controlled medication. It is prescribed by a US-licensed, DEA-registered clinician who is the prescriber of record, never dispensed on request without a clinical decision.

Compounded in the USA

Your injectable testosterone is compounded in the USA by a licensed 503A pharmacy under your prescription. No hidden overseas supply chain, no medication of unknown origin.

Monitored with real labs

Baseline labs are required before any prescription, with follow-up labs every three to six months tracking hematocrit, estradiol, PSA, and lipids so the dose stays matched to you.

Who it's for

For men comfortable with a small weekly injection, who want the most proven format.

Injections suit men who want the most established route to stable testosterone and do not mind a quick self-administered shot. Many men arrive here after reading about pellets; injections are the flexible, adjustable alternative your clinician can fine-tune at any follow-up. Eligibility is a clinical decision made after your labs and history are reviewed.

  • Bloodwork and symptoms point to low testosterone and you want the most proven format
  • You are comfortable with a small weekly or twice-weekly self-injection, or want to learn
  • You want a dose your clinician can adjust over time rather than a fixed implant
  • You value the longest clinical track record among testosterone formats

Every protocol is reviewed by a licensed clinician and prescribed only when appropriate. If injections are not the right fit, your clinician may suggest cream, troche, or a different approach. If TRT is not appropriate, or your state does not support telehealth initiation of Schedule III medications, no prescription is issued and you are never charged for a medication you were not prescribed.

Compounded testosterone is not an FDA-approved drug. TRT is a Schedule III controlled medication, and telehealth initiation of Schedule III medications is not available in every state. Ester, dose, frequency, and any companion compounds are determined by a licensed clinician based on your labs and health history.

Testosterone Injections questions

Things people ask before they sign up.

If something is not here, reach out, we'd rather answer it plainly than have you guess.

How often would I inject?

Most protocols use a small injection once or twice a week to keep your levels steady between doses. Your clinician sets the exact schedule and dose from your labs, and can adjust it at any follow-up.

What is the difference between cypionate and enanthate?

Both are long-acting testosterone esters used for replacement therapy. The differences are subtle and mostly about timing. Your clinician selects the ester that fits your protocol; you do not have to choose between them yourself.

How do injections compare to pellets?

Pellets are implanted and deliver a fixed amount until they wear off, which cannot be adjusted once placed. Injections let your clinician fine-tune the dose and frequency at any follow-up, which is why we offer injections, cream, and troche rather than implanted pellets.

Is compounded testosterone FDA-approved?

No. Compounded testosterone is not an FDA-approved drug. It is prescribed by a US-licensed, DEA-registered clinician and compounded in the USA by a licensed 503A pharmacy. We never imply FDA approval for compounded medications.

Do I need bloodwork before starting?

Yes. Baseline labs are required before any testosterone prescription, and follow-up labs run every three to six months. There is no prescription without labs.

How much do testosterone injections cost?

The online visit is free. If a clinician prescribes, the program is $149/month on the 3-month plan ($447 billed every 3 months), covering the medication, clinician care, and shipping. Lab fees may apply separately depending on your state.

Start with the labs, not the assumptions.

Take the free assessment. If a clinician confirms low testosterone and injections are appropriate, your protocol is prescribed and monitored over time. If not, you are never charged for a medication you were not prescribed.
