Halotestin (Fluoxymesterone substance) is precursor of Methyltestosterone, which is more androgenic by nature than plain testosterone. Anabolic properties of GP Halotest are not very strong thus it’s mostly used for increasing strength rather than muscle gains. This is especially interesting for power lifters, who need to increase strength without increasing own mass and moving to higher weight class. Endogenous androgen’s are responsible for normal growth and development of the male sex organs and for maintenance of secondary sex characteristics. These effects include growth and maturation of the prostate, seminal vesicles, penis, and scrotum, development of male hair distribution, such as beard, pubic, chest, and axillary hair, laryngeal enlargement, vocal cord thickening, and alterations in body musculature and fat distribution. Drugs in this class also cause retention of nitrogen, sodium, potassium, and phosphorus, and decreased urinary excretion of calcium. Androgen’s have been reported to increase protein anabolism and decrease protein catabolism. Nitrogen balance is improved only when there is sufficient intake of calories and protein.

In bodybuilding, GP Halotest mostly used in pre-competition stacks thanks to it’s strong androgenic effect, low aromatization and maintaining low estrogen levels. This leads to decent improvement in muscle hardness and shape, especially if athlete has low body fat. Dosages like 20 mg/ED does not cause water retention. GP Halotest increases recovery, allowing more intense training. In addition, users report increased aggressiveness, which makes it useful not only to bodybuilders or weight lifters but especially to football and hockey players and fighters of all kinds.

GP Halotest (fluoxymesterone) dosage and usage:
Dosage for bodybuilders normally range between 20 and 30 mg/ED. Powerlifters should go with 40 mg/ED, sometimes more. Split daily dosage on two equal parts and take mornings and evenings with substantial amount of water. Could be taken along with meal. Since this is mostly androgenic steroid it requires anabolic component to increase cycle effectiveness. For pre-competition cycle it best stacks with primobolan in order to avoid water retention and “puffy” muscles. For more “gaining” cycles and even contest preparations it could be well stacked with Nandrolone Decanoate, (Deca), Oxymetholone (Anapolon/Anadrol) or Boldenone (Equipoise).

Effects of GP Halotest:
GP Halotest also has a volumizing effect on the physique, and for those with low a body fat percentage, this will cause an immediately more contest ready appearance. This is due, at least in part, to Halos ability to increase mean hematocrit with and hemoglobin level as well as red cell mass.Other possible sides effects: acne,  nasal bleeding, headaches, and of course, it suppresses endogenous hormonal production, so proper PCT is required, athlete should at least use Clomiphene to restore afterwards.  Also increased aggressiveness in males reported. Gynecomastia and high blood pressure are not the case with it.
