Sustanon 250 Cycle Guide: Top 6 Stacks With Dosages
Sustanon 250 – A Comprehensive Review for Patients and Caregivers
Sustanon 250 is a prescription medication that contains four different testosterone esters. It is used primarily to treat low‑level testosterone (hypogonadism) in men, but it also finds use in hormone replacement therapy and bodybuilding. Below we break down everything you need to know about this drug – from how it works to who should avoid it.

1. What is Sustanon 250?
Component Amount Ester How Long It Persists
Testosterone propionate 20 mg Short‑acting 2–3 days
Testosterone phenylpropionate 40 mg Medium‑acting 5–7 days
Testosterone isocaproate 80 mg Long‑acting 10–14 days
Testosterone decanoate 60 mg Very long‑acting 28–30 days
Total: 200 mg of testosterone per vial.
The combination allows a relatively steady release over ~3 weeks, making it convenient for injections every 2–4 weeks.

Typical clinical use
Indication Typical dosage (injection) Frequency
Testosterone deficiency (hypogonadism) in men 200 mg IM or SC Every 14–28 days
Hormone replacement therapy for transgender women (female feminization) 200 mg IM/SC Every 2–4 weeks
Androgen deprivation therapy for prostate cancer 200 mg IM Every 3–4 weeks
Note: The actual dose and interval are adjusted based on serum testosterone levels, clinical response, and side‑effect profile.

Clinical scenarios
Below are five brief examples of how the product might be used clinically.
(Each scenario is purely illustrative; real patient care should follow local guidelines and regulations.)
|
| Patient description | Condition | Proposed dosing (typical) |
|---|---------------------|-----------|--------------------------|
| 1 | 35‑year‑old male with early onset androgen deficiency (low serum testosterone, fatigue). | Hypogonadism | 50 mg intramuscularly once a month. |
| 2 | 28‑year‑old transgender woman (female gender identity) on estrogen therapy seeking masculinization. | Gender‑affirming hormone therapy | 25 mg IM every 4 weeks (dose may be increased to 50 mg if desired). |
| 3 | 40‑year‑old male with benign prostatic hyperplasia and low testosterone after radiation therapy. | Hypogonadism post‑radiation | 75 mg IM once a month. |
| 4 | 45‑year‑old transgender woman on estrogen and progesterone, experiencing fatigue. | Hormone replacement | 25 mg IM every 3 weeks (adjusted based on symptom improvement). |
Note: All dosages above are examples. The actual prescription should be individualized after a full medical evaluation, considering age, comorbidities, concomitant medications, baseline hormone levels, and patient preferences.

4. Practical Guidance for Patients and Clinicians
4.1 Patient Preparation and Consent
Medical History Review: Include prior hormonal therapy, contraceptive use, psychiatric history, cardiovascular risk factors.
Laboratory Baseline: CBC, CMP, fasting lipid panel, thyroid function, pregnancy test if applicable, baseline hormone levels (estradiol, progesterone, LH/FSH), and prolactin.
Informed Consent: Discuss potential benefits, risks, side effects, and the need for follow‑up. Address any concerns about hormonal changes affecting mood or sexual function.
4.2 Monitoring Plan
Parameter Frequency
Symptom diary (sleep, mood, libido) Daily/weekly
Blood pressure & pulse Every visit
CBC / CMP At 1‑month, then every 3 months
Hormone levels At baseline, 3 months, and if symptoms change
Ultrasound of ovaries/hypothalamus (if indicated) As clinically warranted
4.3 Adjustments & Safety Measures
If mood worsens: Consider dose reduction or switch to a different agent.
If significant weight loss/gain: Review dosage and dietary intake.
If new headaches or visual changes: Immediate evaluation for possible intracranial mass.
In case of breakthrough symptoms (e.g., severe nausea, vomiting): Provide antiemetic therapy and reassess medication.
4.4 Documentation & Patient Education
Maintain a detailed log in the EMR: doses, timing, side effects, and any patient-reported changes.
Educate the patient on signs requiring urgent care (severe headaches, vision loss, seizures).
Encourage consistent follow-up appointments to monitor progress and adjust treatment.
Final Thoughts
The scenario illustrates how a clinical presentation that initially appears benign can mask an underlying serious condition. By following a structured approach—thorough history, targeted physical exam, appropriate diagnostic testing, and thoughtful differential diagnosis—clinicians can identify hidden pathologies like pituitary adenomas early. In this case, the patient’s subtle hormonal imbalance manifested as a mild headache but was ultimately due to a prolactin‑secreting macroadenoma causing mass effect on adjacent structures.
Once identified, management focuses on reducing tumor burden and restoring endocrine function, typically via dopamine agonists such as cabergoline or bromocriptine. In refractory cases, transsphenoidal surgery may be required. The key is to treat both the mechanical effects (compression of optic chiasm) and the hormonal consequences (hyperprolactinemia), thereby preventing visual loss and systemic complications.
For clinicians, this scenario underscores the importance of:
Thorough history taking – noting subtle symptoms such as "headache at night" or vision changes.
Detailed ophthalmologic exam – including visual fields to detect early chiasmal involvement.
Early imaging – especially in patients with diabetes or hypertension who develop headaches/vision problems, as small lesions can rapidly progress.
Prompt endocrine work‑up – measuring prolactin and other pituitary hormones when a mass is suspected.
In summary, the patient’s presentation points to a pituitary adenoma (most likely prolactinoma) causing visual disturbance via optic chiasm compression. Early diagnosis, treatment with dopamine agonists, and regular monitoring can preserve vision and reduce systemic complications associated with hormonal imbalance in patients with preexisting cardiovascular risk factors.
