Halotest-25 is the same prohormone found in Promagnon-25 and other prohormones. We researched high and low to find information on this product, but we found very little until we stumbled upon a thread from a bodybuilding forum several years ago. According to that thread, the active ingredient in Halotest-25 will increase strength and aggressiveness, but the negative side effects are relatively mild compared to other prohormones.

Prohormones are not designed for use as weight loss agents, but Halotest-25 is considered a dry booster, which means there is very little water weight gain and leaning out while taking the prohormone is an option.

List of Ingredients


  • 4-chloro-17a-methyl-andro-4-ene3, 17bdiol

Absorbtech Delivery System:

  • Bioprene
  • Vanadyl Sulfate

Product Features

Halotest-25 is not your average supplement. This prohormone is taken by bodybuilders who want to increase muscle mass and strength with few of the known side effects associated with prohormones. Prohormones are not weight loss supplements, so there is no reason for the dieter to take this supplement in place of a fat burner even though bodybuilders claim to lean out on the supplement.

The information we found on Halotest-25 is limited to forum posts as this prohormone does not appear to be for sale any longer in the United States. Many of the prohormones once available to athletes and bodybuilders are now listed on a banned substance list and even if a prohormone is not listed, it is likely considered an illegal substance by the sanctioning committee working with your athletic or bodybuilding event.

The main effect of Halotest-25 is aggression and increased strength. Muscle mass comes as a result of increased strength. After stopping the cycle of Halotest-25, which can last up to eight weeks, you will lose some of the strength and subsequently some of the muscle gain.

Halotest-25 is a prohormone that is available from Powerlab Nutrition. Powerlab Nutrition sells the prohormone despite the fact that many prohormones are currently illegal. We were able to find the prohormone for sale on an outside website as well. Prohormones increase testosterone levels, which results in increased muscle mass, strength and aggression. Together, this makes for a pretty mean athlete or bodybuilder, but there are also side effects that need to be taken into consideration.
