Anavar Side Effects

Anavar, like many other anabolic steroids, can cause some undesirable side effects that vary based on several factors. Anavar side effects are typically considered mild when they do occur, and most users report they resolve on their own after the body acclimates to the hormones.

Regardless, understanding the side effects can help you take the proper course of action should you experience them, and it will also help you feel more comfortable during your Anavar cycles.

Stop Using Anavar if You Experience Signs of an Allergic Reaction

Signs of an allergic reaction to Anavar may include, but are not limited to:

  • Rashes or hives accompanied by itching, pain, or discomfort;
  • Swelling of the extremities, including the arms, legs, fingers, and toes;
  • Facial swelling, especially of the lips, eyes, tongue, and throat;
  • Dangerously low blood pressure; and/or
  • Difficulty breathing.

If you experience any of these Anavar side effects, you may be experiencing a dangerous allergic reaction called anaphylaxis. You should immediately stop using the compound and seek emergency medical treatment.

Anavar Side Effect: Testosterone Suppression

Anavar Side EffectsAlthough it’s usually regarded as mild in nature, Anavar does have the potential to suppress the male body’s natural production of testosterone. In fact, this can occur within the first few days of treatment.

Though you may not notice it at first because Anavar binds to the same receptors and thus acts much like testosterone in your body, it can cause problems down the line once you’ve finished your cycle.

For this reason, many men choose to supplement their Anavar with exogenous testosterone. This helps to keep testosterone levels in the normal range during their cycles, and it helps them avoid any Anavar side effects that may be associated with low testosterone levels, including things like testicular atrophy.

It’s also important to follow a post-cycle therapy regimen carefully so you can help your body start producing its own testosterone after your cycle ends. The table below shows the amount of testosterone you should use based on its type.

Testosterone TypeRecommended Dose
Testosterone Cypionate
100mg to 500mg per week
Testosterone Enanthate
500mg to 1000mg per week
Testosterone Propionate
100mg to 200mg every other day
Test Phenylpropionate
100mg to 200mg every other day
*Testosterone Decanoate
250mg to 1000mg per week
Testosterone Undecanoate (Andriol)
200mg to 400mg per day
**Sustanon
250mg to 750mg per week

* Until very recently, testosterone decanoate was not available as a stand-alone therapy. It is now available under the brand name Neotest 250.

* *Sustanon is a blend of testosterone esters, and some of these, such as testosterone isocaproate and testosterone caproate, are incredibly difficult to find as stand-alone compounds.

When using this chart as a point of reference, it’s important to remember that beginners should start at the low range of the recommended Anavar dosage and work their way up; more experienced bodybuilders can start at the higher end of the range.

Hepatotoxicity (Liver Damage)

One of the most concerning Anavar side effects is its hepatotoxicity, which is a term that means it is toxic to the liver. The compound has been alkylated so that it can survive its trip through the liver and still be useful as a performance enhancer, and while it works, it may also cause damage along the way. Signs of liver damage may include, but are not limited to:

  • Abdominal pain, which may range from mild to severe;
  • Dark yellow or brown urine;
  • Pale stools;
  • Increasing pain in the joints;
  • Fatigue that does not resolve, even after rest; and
  • Jaundice (a buildup of a liver enzyme known as bilirubin), which turns the whites of the eyes and skin a yellowish hue.

If you experience any of the aforementioned symptoms of liver damage, stop using Anavar and contact your doctor right away.

Who Should Avoid Anavar?

Although Anavar is one of the mildest anabolic steroids and many people consider it safe, there are some people who should avoid using it. Certain medical conditions increase health risks, which means it’s important to avoid Anavar or, at the very least, consult a doctor before using it.

  • High cholesterol – There is some evidence to suggest that Anavar, along with many other anabolic steroids, can worsen lipid profiles. Those who have high cholesterol should avoid it for this reason.
  • Liver or kidney diseases – Though Anavar is mild, it is known for being hard on the liver and kidneys – especially in large doses over extended periods of time. If you have (or have had) liver or kidney disease, Anavar 50mg may not be the best choice for you.
  • Heart disease – Some studies have linked the use of anabolic steroids like Anavar to an increased risk of heart attack and cardiac events in people who have underlying conditions. Anyone who has a heart condition should consult a physician before using this product.
  • Breast and prostate cancer – Because Anavar is a hormone, there is a chance that it may create a long-term imbalance that could lead to breast and prostate cancers. Individuals who are at high risk for these conditions, who have them, or who have had them in the past should avoid Anavar.

Anavar Side Effects to Watch For

Not everyone will experience Anavar side effects, and those who do won’t experience them at the same level of severity. For example, two otherwise healthy people using the same dose of Anavar may experience completely different side effects. The following is a list of reported side effects and what to watch for in terms of severity.

  • Gastrointestinal distress – Some of the most commonly reported Anavar side effects are related to the gastrointestinal system. These include things like nausea, vomiting, diarrhea, and heartburn, among others. Over-the-counter remedies may be used to treat these symptoms. Though mild side effects that go away on their own after the first few days are normal, these should be reported to your doctor if they persist or if they become bothersome.
  • Headaches – Because Anavar influences your body’s natural hormone production, you may experience mild to moderate headaches as your body adjusts. You can treat these with over-the-counter pain relievers, and they should go away within the first few days of use. If they do not, reduce your Anavar dose. If your headaches become severe and/or debilitating, which is extremely rare, see your doctor.
  • Skin changes – Some users experience mild skin changes as their bodies adjust to the changing hormone environment. For example, your skin may become oilier than before, and you may be more prone to breakouts. Some people report being more sensitive to the sun, but this is easily mitigated with shade and sunblock, when needed. In a few people, slight changes in skin color have been reported. This is quite rare.
  • Changes in sex drive – Both men and women have reported increased and decreased libido as one of the more common Anavar side effects. This will differ from person to person, and like many of the other side effects, it tends to balance itself in time. Again, this is the result of fluctuations in hormones caused by the introduction of Anavar.
  • Sleep interruptions – It’s common for people who are new to taking Anavar to experience insomnia and interrupted sleep. The best way to overcome this is to use an over-the-counter sleep aid, such as one containing diphenhydramine, to help you get the rest you need. In most cases, users only report disrupted sleep patterns for the first few days of use.
  • Mood changes – Some people have experienced mild mood changes because of the changing hormones, though these often level out in a few days and pose no real threat to the user. In a few very rare cases, the use of Anavar and other AAS has led to significant depression and anxiety. If you experience these, you should talk to your doctor about these Anavar side effects.

When compared to other anabolic steroids, Anavar side effects are quite mild. However, it’s important to understand what you should expect, not only for your peace of mind, but also for your health. If you experience bothersome side effects, or if you’re concerned about your experience, please do not hesitate to seek medical advice.
