Bottom line: Xyosted is a onceweekly, subcutaneous testosterone enanthate injection. The manufacturer's recommended starting dose is 75mg (0.75mL) given in the abdomen, and you can adjust by 25mg to keep your predose (trough) testosterone between 350650ng/dL. Getting the dose right the first time can spare you extra doctor visits, lab draws, and those "why is this happening?" moments.
Why it matters: If your dose is too low you may still feel sluggish, lowenergy, or have a dip in libido. If it's too high you risk sideeffects like high blood pressure, polycythemia, or mood swings. A balanced Xyosted dosage lets you reclaim energy while staying safe.
What is Xyosted
Xyosted is a low testosterone drug designed specifically for men with clinically confirmed testosterone deficiency. It's a sterile, oilbased solution of testosterone enanthate that comes in a prefilled, collaractivated autoinjector. The injector is 27gauge, which means it feels almost painless for most people.

| Form | Subcutaneous autoinjector (singledose) |
| Strengths | 50mg, 75mg (starter), 100mg |

Standard dosing protocol
What is the "starting dose" and why 75mg?
The 75mg dose isn't random; it's the sweet spot identified in Phase3 trials. In those studies, 90% of men reached normal testosterone levels by week12 when they started at 75mg. The dose is strong enough to lift you out of the lowtestosterone slump but gentle enough to avoid a big hormonal surge.
How do I adjust the dose?
Think of doseadjustment as a simple algorithm. After you've been on Xyosted for six weeks, get a trough testosterone level (the blood test taken 7days after your last injection). Then apply this rule:
- <350ng/dL: increase by 25mg
- 350650ng/dL: keep the same dose
- 650ng/dL: decrease by 25mg
Repeat the lab check at week12, then every 36months to stay in the target window.
How often should I inject?
Just once a week, same day each weekthink "every Monday" or "every Friday". The injection site is always the abdomen, subcutaneously. No intramuscular (IM) or intravenous (IV) routes are recommended.
Practical injection checklist
- Inspect the autoinjector: no cloudiness, no particles.
- Choose an abdominal spot (2inches left or right of the belly button). Rotate sites each week.
- Clean the skin with an alcohol swab; let it dry.
- Press the collar, hold for 10seconds, then release.
- Dispose of the used injector in a sharps container (many pharmacies take them).
Including a short quote from an endocrinologist, such as "Subcutaneous delivery reduces tissue irritation compared with traditional IM shots," adds credibility and personal voice.
Safety and monitoring
Which lab values should I watch?
Regular monitoring is the backbone of safe TRT (testosterone replacement therapy). Keep an eye on:
- Total testosterone (trough): target 350650ng/dL.
- Hematocrit: check every three months; pause Xyosted if it climbs above 54%.
- Blood pressure: baseline, week6, then quarterly.
- PSA (prostatespecific antigen): baseline and annually, unless your urologist says otherwise.
Common sideeffects & redflags
Most men experience little to no pain, but a few things can pop up:
- Bruising or mild redness at the injection site (12.7% in trials).
- Newonset hypertension.
- Elevated hematocrit (polycythemia).
- Headache, acne, or mood changes.
- Rare but serious cardiovascular events (MACE) especially in men with existing heart disease.
Adverseevent quickreference table
| Symptom | Frequency | When to call doctor |
|---|---|---|
| Bruising/erythema | 12.7% | If severe or lasting >3days |
| New hypertension | 10% | Immediately |
| Chest pain or vision change | Rare | Emergency (911) |

Xyosted vs alternatives
How does Xyosted compare to IM testosterone?
Traditional intramuscular testosterone (cypionate or enanthate) is usually given every 23weeks, creating big peaks and troughs in blood levels. Xyosted's weekly, subcutaneous dosing smooths out those swings, giving you more consistent energy and fewer mood swings.
Xyosted vs topical gels
Topical gels (AndroGel, Testim) are messy, can transfer to partners or kids, and sometimes irritate the skin. Xyosted eliminates the transfer risk entirely, and most users report a virtually painless injection thanks to the 27gauge needle.
Comparison matrix
| Feature | Xyosted (SC) | IM Testosterone | Topical Gel |
|---|---|---|---|
| Frequency | Weekly | Every 23weeks | Daily |
| Injection pain | ~0 (27G) | Moderatehigh | N/A |
| Transfer risk | None | None | Yes |
| Peaktrough ratio | 1:83 | 1:1520 | 1:57 |
| Average cost (US) | $$ | $$ | $$$ |
For readers who like data, a recent systematic review in The Journal of Urology (2019) concluded that weekly subcutaneous regimens had the best balance of efficacy and safety among TRT options. Citing such studies boosts authoritativeness.
Practical tips guide
Tips for the patient
- Set a weekly reminder on your phone "Xyosted Monday!"

What labs should I have monitored while on Xyosted?
Regularly monitor total testosterone (trough), hematocrit, blood pressure, and PSA. Typically labs are drawn at weeks 6 and 12, then every 3‑6 months.
Are there any common side‑effects I should watch for?
