Chemical Structure and Properties

Halotestin, or Fluoxymesterone, is a 17-alpha alkylated anabolic androgenic steroid derived from the hormone testosterone. The molecular formula of Halotestin is C20H29FO3, and it has a molecular weight of 336.44 g/mol.

The addition of a fluorine atom at the 9th carbon position and a hydroxyl group at the 11th carbon position significantly increases its androgenic potency compared to its parent compound, testosterone.

The 17-alpha alkylation in Halotestin’s chemical structure allows it to survive first-pass liver metabolism when taken orally, making it more bioavailable compared to non-alkylated steroids.

This modification, however, also increases the hepatotoxicity of the compound, which can lead to liver stress and damage when used for extended periods or at high doses.

How Halotestin Works for Performance Enhancement

One of the most notable effects of Halotestin is its ability to significantly increase strength and aggression in users. This is particularly useful for athletes participating in strength-based sports, such as powerlifting and strongman competitions, where maximizing strength is a key determinant of success.

Many users have reported experiencing rapid strength gains within the first few weeks of a Halotestin cycle, allowing them to lift heavier weights and perform more demanding exercises.

The increased aggression associated with Halotestin use can also be advantageous in certain sports where mental tenacity and a competitive edge are important factors. This heightened sense of aggression may help athletes push through plateaus and overcome physical and mental barriers during training or competition.

However, it’s important to note that this increase in aggression can also have negative consequences if not managed properly, such as causing interpersonal conflicts or leading to reckless behavior.

Fat Loss and Lean Muscle Preservation

Another notable effect of Halotestin is its ability to promote fat loss while preserving lean muscle mass. This makes it a popular choice for bodybuilders and athletes looking to improve their body composition and achieve a more defined, muscular appearance.

Halotestin helps to boost the body’s metabolic rate, resulting in an increase in the number of calories burned throughout the day. This, in turn, promotes the breakdown of adipose tissue, leading to a reduction in overall body fat.

Simultaneously, Halotestin helps to preserve lean muscle mass by promoting protein synthesis and inhibiting muscle breakdown, even during periods of caloric restriction.

This ensures that users can continue to build and maintain muscle while shedding unwanted body fat, ultimately enhancing their athletic performance and physical aesthetics.

Halotestin for Sale


How do I know if my product is real or counterfeit?

Sometimes, it can be difficult to determine whether you’re about to buy real Halotestin or a counterfeit product. In fact, some of today’s more advanced underground labs can design tabs that look just like the real thing. When Halotestin comes direct from a pharmaceutical company, it is in a blister pack. If you are being sold a bottle of loose pills, this should raise warning flags. What’s more, you should also research the seller very carefully and read reviews specific to that particular company.

Can I buy and use it for mass gains?

Halotestin is not the best choice for mass gains. Though most men can use a  cycle for strength and not worry about gaining, those who are new to anabolic steroids may actually put on a few pounds of muscle. This depends on their diet and workout habits, as well. Of course, it should be noted that it is not a good choice for beginners and should only be used by those who have some experience with other anabolic steroids.

What’s the best way to take my daily dosage?

Though most people do not experience any issues with taking their entire dosage all at once, some people – including those who choose to use the maximum 40mg daily dose – will break their doses in half and take them twice per day. Side effects may include gastrointestinal issues or sleeplessness for some people, so breaking the dose in half and taking the last one around 4 pm can help mitigate these.

How much does it usually cost?

Because real Halotestin is often hard to come by, it is considerably more expensive than many other steroids. However, individuals who are interested in tremendous strength, speed, and power consider it an investment. Per several websites, the average cost of Halotestin is roughly $85 for 100 5mg tablets.

What kind of results should I expect?

Halotestin results can certainly vary, but almost everyone who uses it experiences superior gains in strength and speed. Their stamina and endurance improve significantly, they find they are faster on their feet, and they are able to lift more than ever before. Individual Halotestin results will vary significantly, however, depending on factors like dosage and response.

Where should I look for unbiased reviews?

Before you buy Halotestin, it is vital that you take the time to read reviews of not only the compound but also the company selling it. You first need to discover whether Halotestin is right for you in the first place, and if it is, you need to know where you can get it safely. Online forums are great sources of unbiased information that is in no way influenced by individual sellers. Take your time to read multiple opinions and then use your best judgment to make your decision.
