Overview and History of HALOMED 5 (Fluoxymesterone)

HALOMED 5 (Fluoxymesterone) is a synthetic derivative of Testosterone hormone, in particular, that is a derivative of Methyltestosterone (Testosterone that has been Methylated). HALOMED 5 (Fluoxymesterone) is a very strong oral anabolic steroid that is unable to aromatize into Estrogen. This compound also exhibits very strong androgenic strength, it possesses an anabolic strength rating of 1900 and an androgenic strength rating of 850. That is very important to understand that Methyltestosterone is slightly stronger than Testosterone itself.

In comparison with Testosterone, which anabolic and androgenic strength ratings are 100 respectively, HALOMED 5 (Fluoxymesterone) is 19 times stronger. At the very beginning, HALOMED 5 (Fluoxymesterone) was used in the medical field for the maintenance and gaining of lean mass and tissue repair following various conditions of trauma (burns, bone fractures, malnutrition, muscle-wasting diseases, treatment of paraplegics, and as an adjunct to chronic administration of corticosteroids). HALOMED 5 (Fluoxymesterone) was approved for the treatment for androgen deficiency in men, breast cancer treatment in females, and for the treatment for osteoporosis in postmenopausal women. Because of its high degree of hepatotoxicity, today the lists of approved medical uses for HALOMED 5 (Fluoxymesterone) have been changed, leaving only the treatment of male androgen deficiency and female breast cancer treatment.

Chemical Characteristics of HALOMED 5 (Fluoxymesterone)

HALOMED 5 (Fluoxymesterone) possesses an added methyl group on the 17th carbon (known as carbon 17-alpha). It is also halogenated at carbon 9-alpha. Halogenation is the replacement of one or more hydrogen atoms in an organic compound (in this case, Testosterone) by a halogen, usually resulting in said halogen becoming bound to the compound. A halogen refers to a specific category of 5 related elements on the periodic table (Fluorine, Chlorine, Bromine, Iodine, and Astatine). If we are talking about HALOMED 5 (Fluoxymesterone), that is Testosterone that has been halogenated with Fluorine (as a fluoro group) whereby the Fluorine atom has been bound to carbon 9-alpha. The final modification that HALOMED 5 (Fluoxymesterone) possesses is its addition of a hydroxyl group (an oxygen atom bound to a hydrogen atom) at carbon 11-beta on the Testosterone molecule. The halogenation is also responsible for the major increase in androgenic and anabolic strength in comparison to Testosterone and Methyltestosterone. The addition of the hydroxyl group at carbon 11-beta is what is responsible for restricting the ability for HALOMED 5 (Fluoxymesterone) to interact with the aromatase enzyme, and therefore become unable to convert into Estrogen in the body.

Properties of HALOMED 5 (Fluoxymesterone)

HALOMED 5 (Fluoxymesterone) gives a vast increase in strength and lean muscle growth. Athletes and bodybuilders can enjoy those qualities. The methylation of the 17th carbon is the reason why the use of HALOMED 5 (Fluoxymesterone) causes a degree of hepatotoxicity in the body. Meanwhile, the big advantage with HALOMED 5 (Fluoxymesterone) is that because of its inability to interact with the aromatase enzyme and thereby avoid any Estrogen conversion, there is no risk of any Estrogen-related side effects.

HALOMED 5 (Fluoxymesterone) Side Effects

HALOMED 5 (Fluoxymesterone) contains two main characteristics to worry about: it is regarded as a very androgenic compound, stronger than Trenbolone which is regarded as the strongest androgen, and its higher risk of hepatotoxicity. HALOMED 5 (Fluoxymesterone) side effects do not include any Estrogen-related side effects, no matter what the dose is.

HALOMED 5 (Fluoxymesterone) is a very strong androgen, meaning that there is a very high risk of potential androgenic side effects. Many bodybuilders and athletes even wish to experience such androgenic side effects like the increase in competitive drive and aggression.
HALOMED 5 (Fluoxymesterone) is an anabolic steroid that possesses a very high affinity for interaction with the 5-alpha-reductase (5AR) enzyme, which is the enzyme responsible for the conversion of androgens into (normally) much stronger androgenic metabolites. Studies have shown HALOMED 5 (Fluoxymesterone) can convert into a very large amount of stronger androgens by way of the 5-alpha-reductase enzyme. Therefore, it may be possible to reduce the intensity of androgenic side effects through the use of a 5-alpha-reductase inhibitor, such as Finasteride, Dutasteride, or Propecia, which all serve to inhibit the 5AR enzyme and prevent a reduction of androgens into their stronger androgenic metabolites. Still, attention should be paid because the use of these 5AR inhibitors may not decrease the androgenic strength of HALOMED 5 (Fluoxymesterone) because HALOMED 5 (Fluoxymesterone) itself is a very androgenic hormone as it is.

Possible androgenic side effects include increased sebum secretion (oily skin), increased bouts of acne (linked to increased sebum secretion), bodily and facial hair growth, benign prostatic hypertrophy (BPH), and the increased risk of triggering Male Pattern Baldness (MPB). The same like all other anabolic steroids, the use of HALOMED 5 (Fluoxymesterone) can result in HPTA and Endogenous Testosterone Production Side Effects. The administration of HALOMED 5 (Fluoxymesterone) will suppress and/or shut down natural endogenous Testosterone production for the duration of its use. The negative cardiovascular risks and cholesterol changes can occur during the use of HALOMED 5 (Fluoxymesterone).

Dosages and Administration of HALOMED 5 (Fluoxymesterone)

HALOMED 5 (Fluoxymesterone) is not a very popular anabolic steroid, which is fairly difficult to find. It is also very specific in terms of its uses and purposes. HALOMED 5 (Fluoxymesterone) dosages are very odd or very different from the doses of most other anabolic steroids.

HALOMED 5 (Fluoxymesterone) exhibits considerable increases in strength without the very dramatic increases in muscle size. That is the reason why it is very popular among athletes in sports in which increases in weight is not needed (such as wrestling, sprinting, boxing, etc.).

The medical dosage of HALOMED 5 (Fluoxymesterone) for the treatment of male androgen deficiency (andropause or hypogonadism): the original prescription doses are utilized in a range of 2 – 10mg daily. Anyway, nowadays HALOMED 5 (Fluoxymesterone) modern doses will be in the range of 5 – 20mg daily. During the treatment for female breast cancer patients, the dose is often much higher, in the range of 10 – 40mg daily.

If separate HALOMED 5 (Fluoxymesterone) doses can be provided for the three separate types of users, it should be beginner, intermediate and advanced users. The dose for beginners should be in the range of 10 – 20mg daily, providing some solid increases in drive, aggression, and strength. Intermediate users will be happy to find greater strength and drive increases with doses of 20 – 30mg per day. While, advanced users dosage should be up to 30 – 40mg daily, although this should be done with the utmost caution.

Female athletes are not recommended to use HALOMED 5 (Fluoxymesterone) due to their possession of an extremely strong androgenic strength rating. HALOMED 5 (Fluoxymesterone) holds a higher chance and incidence of the manifestation of virilization in female users. Proper administration and timing are very important during the use of HALOMED 5 (Fluoxymesterone). HALOMED 5 (Fluoxymesterone) half-life is just short enough to allow splitting up the doses throughout the day – should be, no more than usually twice per day. Steady blood plasma levels should be kept at all times for optimal results.

HALOMED 5 (Fluoxymesterone) Cycles and Uses

Because of the lack of popularity of this compound, there is very limited information about HALOMED 5 (Fluoxymesterone) cycles available. HALOMED 5 (Fluoxymesterone) cycles will usually include HALOMED 5 (Fluoxymesterone) to provide an extra androgenic effect in cycles where weaker androgens are used (such as DECAMED 250 (Nandrolone Decanoate) or EQUIMED 250 (Boldenone undecylenate)), ‘hardening' the physique during cutting or pre-contest phases, and for the benefits of increased aggression and strength.

HALOMED5 (Fluoxymesterone) cycles are limited because HALOMED5 (Fluoxymesterone) can only be utilized for 6 – 8 weeks, and often even less.

Example of the Beginner HALOMED 5 (Fluoxymesterone) Cycle, where mass gaining is the primary concern. 12 weeks of total cycle time:

Example of the Intermediate HALOMED 5 (Fluoxymesterone) Cycle. 12 weeks of total cycle time:
  • Weeks 1 – 12: TESTOMED E 250 (Testosterone Enanthate) at 100mg/week. DECAMED 250 (Nandrolone Decanoate) at 400mg/week.
  • Weeks 1 – 6: HALOMED 5 (Fluoxymesterone) at 30mg/day. Such cycles provide the ability to utilize ‘mild’ anabolic steroids (such as DECAMED 250 (Nandrolone Decanoate) or EQUIMED 250 (Boldenone undecylenate)) with the addition of HALOMED 5 (Fluoxymesterone) to provide a very satisfying anabolic effect on the user with a lack of Estrogen in the body.

Example of the Advanced HALOMED 5 (Fluoxymesterone) Cycle. 10 weeks of total cycle time:
  • Weeks 1 – 10: TESTOMED P 100 (Testosterone Propionate) at 100mg/week (25mg every other day). TRENBOMED A 100 (Trenbolone Acetate) at 400mg/week (100mg every other day).
  • Weeks 6 – 10: HALOMED 5 (Fluoxymesterone) at 40mg/day. This is also a great example for pre-contest cycle stack with the inclusion of HALOMED 5 (Fluoxymesterone) in the final 6 weeks of the cycle hypothetically leading up to the contest show. This is considered an extremely androgenic cycle, perfect for users who wish to come out at the end of the cycle during the show with the extremely hard and defined 3D look to the physique due to the presence of two of the strongest androgens available: Trenbolone and Halotestin.
