Sustanon is an injectable medicine used for treating Low Testosterone (Low T) or Hypogonadism in men. It contains Testosterone Isocaproate as an active ingredient and is available in strengths of 100 and 250 mg. Although the injection is highly effective in restoring hormonal balance, it can cause side effects in some men, like any other medication.
Common effects, such as injection-site discomfort or mood swings, are generally mild and temporary. Rare effects like liver issues and blood clots are more severe and demand immediate medical attention.
Understanding these adverse reactions is essential to administering the injection safely. This article will discuss both common and rare Sustanon side effects, how to manage them, and who should not use Sustanon injection. This will help you make informed decisions about its usage.
Common Sustanon side effects
Sustanon, used for Testosterone Replacement Therapy (TRT), can trigger several unwanted effects that are usually mild or moderate. They subside on their own as the body adjusts to the strength and changing levels of testosterone. This will help you realize what is normal and temporary and when they need medical attention.

You might experience one or more of these common side effects of Sustanon:
- Reaction at the injection site: Since this formulation is oil-based, it can cause mild soreness, redness, or swelling at the injection site.
- Musculoskeletal pain: Joint discomfort and muscle stiffness can occur, as TRT is known to trigger muscle development.
- Physical changes: The development of acne, increased body hair, oily skin, and changes in facial appearance can occur in some users. This is because testosterone stimulates the hair follicles and sebaceous glands.
- Cardiovascular and weight issues: Some men can experience slight palpitations or a mild increase in blood pressure. It occurs when testosterone affects fluid balance in the body. Moreover, it can cause fluid or water retention, leading to increased body weight.
- Gastrointestinal issues: Effects like mild abdominal discomfort, bloating, and nausea can occur.
- Mood and sleep disruption: During the initial stages of TRT, fluctuations in testosterone levels can lead to emotional instability, anxiety, and irritability. Some men can also experience restlessness or Insomnia.
- Prostate changes: Testosterone injection can cause a slight increase in prostate size (non-cancerous), resulting in weak urinary flow or increased urination frequency.
Rare and serious side effects
Some side effects are rare, but when they do occur, immediate medical attention is required. These effects typically arise with long-term use or high doses that increase testosterone levels excessively. They can also occur in people who already have certain underlying risk factors. Such uncommon but severe effects are as follows:
- Liver problems: Testosterone can create stress on the liver in rare cases. It can also lead to dark urine, Jaundice, or abdominal pain.
- Masculinization in women: This testosterone product is FDA-approved for use in men only. Therefore, if a woman takes it, it can lead to facial hair growth, a deep voice, and menstrual changes.
- Increased Red Blood Cell (RBC) count: TRT can sometimes cause an abnormal increase in RBC count, leading to dizziness or headaches, and the formation of blood clots.
- Decreased sperm count: Long-term use can reduce fertility by affecting the natural function of the testes and lowering sperm count.
- Pulmonary Microembolism: Since blood clot formation is a side effect, these clots can travel to the small blood vessels in the lungs and block them. It results in decreased blood flow and oxygen levels. This is called Pulmonary Microembolism.
- Allergic reaction: Individuals who are allergic to any ingredients in Sustanon injection can experience difficulty breathing, a rash, or swelling.
- Edema: As mentioned before, fluid retention is a common side effect. This can further result in swelling of the feet or ankles, a condition known as Edema.
- Erection issues: There are chances of damage to penile tissue due to frequent erections and Priapism.
People who should avoid Sustanon
Sustanon is highly effective, but like any other medication, it is not safe to use in certain groups with specific diseases or with particular medications. Men allergic to the ingredients of this injection should avoid it altogether. Moreover, as discussed earlier, TRT is not approved for women. As a result, pregnant and breastfeeding females should also avoid it.
The following points discuss the conditions and medications that are harmful when men are on hormonal therapy for Low T:
With existing medical conditions
People with these conditions should not use Testosterone injection:
- Sleep disorder: Since one of the side effects of the medication is to trigger sleep disturbances, people with severe Sleep Apnea, where breathing stops and restarts repeatedly during sleep, should avoid it.
- Severe Hypertension and heart disease: TRT can worsen fluid retention and circulation in these conditions.
- Kidney and liver disease: The hormonal injection can further strain the kidneys and liver by affecting kidney blood flow and increasing liver enzyme levels.
- Prostate Cancer or Breast Cancer: Hormonal therapy for Low T can promote the growth of existing cancer cells in men.
- History of blood clots: Men with a history of blood clots are at higher risk of new clot formation or worsening of existing clotting due to increased RBC count and blood thickness.
People with certain medications
Some medicines can interact with Sustanon to trigger adverse reactions. Therefore, men using testosterone injection should avoid:
- Blood thinners (Warfarin): Testosterone can enhance Warfarin’s effects by targeting clotting factors. This can make the blood too thin, increasing the risk of bleeding.
- Corticosteroids: They can increase the risk of fluid retention when used in combination with the injection.
- Diabetic medicines: Do not combine medicines for Diabetes with Testosterone-containing injectable medications, as this can affect blood sugar control.
- Opioids: They are known to disturb the body’s natural testosterone production, increasing the chances of hormonal imbalance.
How to manage the negative effects of Sustanon
Sustanon injection side effects can be managed with medical guidance and the right strategies. Proactive precautions also help maximize benefits from the hormonal therapy. The following are the tips to reduce the occurrence of adverse effects:
- Regular monitoring: Ensure regular check-ups to monitor lipid profile, blood pressure, RBC count, and liver function. It will help detect the issues early.
- Manage weight gain: Exercise regularly and maintain a healthy diet to stabilize metabolism and reduce fluid retention.
- Use correct injection technique: To prevent injection-site bruising and pain, choose the correct needle size and administer the injection intramuscularly.
- Stay hydrated: Proper hydration reduces the risk of blood clotting and supports kidney function.
- Dosage adjustments: If common side effects persist for an extended period, consult a doctor to consider a dose reduction.
- Smoking and alcohol use: Avoid smoking and alcohol, as they put stress on the liver and cardiovascular function. When combined with TRT, this additional stress can increase the risk of side effects such as High Blood Pressure.
Always start the treatment under a professional’s supervision. It will ensure the accurate dosing and monitoring of your body response. Moreover, consult a doctor if rare or severe side effects are observed or if common side effects persist for longer.
Conclusion
Sustanon injection is an effective treatment for Low T for men, but like any hormonal therapy, it comes with certain side effects. Common unwanted effects like injection-site discomfort, physical changes, musculoskeletal pain, and mood changes are usually mild and temporary. Rare but severe issues like Pulmonary Microembolism, Edema, liver issues, and Priapism require urgent medical attention.
Men with Prostate Cancer, allergies to its ingredients, sleep disorders, a history of blood clots, heart, kidney, and liver issues should completely avoid this medication. Moreover, men on Opioids, corticosteroids, or blood thinners should not take TRT due to possible interactions. Most of the Sustanon side effects can be managed with a doctor’s guidance, dose adjustments, healthy lifestyle habits, regular monitoring, and injecting the medicine correctly.

However, evidence is limited, and it is not considered a standard treatment. Consult a doctor for safe approaches to manage knee pain.
How to reduce pain from testosterone injection?
To reduce pain from testosterone injection and minimize the risk of adverse effects from incorrect testosterone administration into the muscles, choose the upper outer buttock as an injection site, as it has thicker muscle and fewer pain receptors. Wipe the skin with alcohol and relax the muscle. Apply a cold compress to minimize swelling after the injection.
Does Sustanon lead to hair loss?
