Bottle recommended dosage: 1 capsule a day for the first five days, and if necessary, increase to two capsules for the remainder of the protocol. Do not use for more than 6 weeks. And then take 2 weeks off cycle and you can return for another 6 week cycle.

Warning: Do not use if under the age of 18. Do not exceed recommended dosage during 24 hour period.

Another Halodrol/Halovar clone. Halodrol/Halovar is a proven performer, mild enough for noobs yet strong enough that most users see good results. Often used in a stack by more advanced/experienced users.

Something that concerns me here is the company literature reading "And then take 2 weeks off and you can return for another 2 week cycle."

Uh.... I wouldn't recommend that. The bare minimum recommendation is to take at least as much time between cycles that you spend on them, so it goes to reason if you use this for 6 weeks, you need to take 6 weeks off. And you need to be doing proper PCT here too; 2 weeks isn't enough time for that. And for stronger/more toxic compounds (like, say, Superdrol or Boladrol), you should probably be taking 2x as long between cycles as you are on.

Yes, this is a 17a methyl, so use liver support and stay away from the booze and Tylenol.

As for PCT, opinions are mixed. If you're running this as a stand-alone, and depending on your personal genetics, you might be able to get away with an over-the-counter PCT. Still, to be sure, I'd recommend a nolvadex or chlomid SERM for best results.

4-chloro-17a-methyl-androst-1,4-diene-3-17b-diol (Halovar)

A clone of Halodrol (4-chloro-17a-methyl-androst-1, 4-diene-3b,17b-diol)

Halodrol is a 17aa steroid that converts to the steroid oral Turinabol after interaction with 3b-HSD at an estimated rate of about 5%. Because of this low conversion, doses must be higher than other 17aa pro-steroids. However, it is suspected that Halodrol has decent potency without conversion as good results are seen despite the relatively low conversion to Turinabol. Halodrol appears to be about as potent as testosterone, and significantly less androgenic.

Because of the 4-chloro group, halodrol has no progestational effects, it cannot interact with the aromatase enzyme, and it produces inactive 4-chloro-DHT metabolites. This makes androgenic side-effects such as hair loss, high blood pressure, acne and prostate enlargement less likely.

The lack of androgenic potency might be expected to create problems with gyno, however the low SHBG binding affinity has minimal interference with SHBG levels and/or freely circuiting estrogen and testosterone. It does not appear that halodrol has a significant gyno risk.

Because halodrol must be used at such a high dose to see noticeable effects, liver toxicity may become an issue. Therefore it is recommended to use a liver protecting supplement before and during halodrol cycles.

Gains from Halodrol generally take a few weeks to notice, but users can expect solid increases in strength, lean muscle mass, improved vascularity and minimal water retention. This allows some of the gains to be kept after the cycle if good diet and training are continued. Quick dramatic gains in size and strength are not generally noticed with Halodrol.

H-Drol is one of the most popular and proven compounds on the market and is considered good for beginners due to it's reputation for minimal side effects and dry gains that are relatively easy to maintain after the cycle is complete.

Dicalcium Phosphate

Dicalcium phosphate, also known as calcium monohydrogen phosphate, is a dibasic calcium phosphate. It contains about 29.5 percent calcium in its anyhydrous form. Manufactured from phophoric acid, dicalcium phosphate is used as an antioxidant in food, an abrasive agent in toothpaste (dicalcium phosphate dihydrate) as well as being a firming agent

Dicalcium phosphate is mainly used as a dietary supplement in prepared breakfast cereals, dog treats, enriched flour, and noodle products. It is also used as a tableting agent in some pharmaceutical preparations, including some products meant to eliminate body odor. It is used in poultry feed.

In some instances, DCP can seriously effect the absorption of other supplements. According to the June 1997 Journal of Clinical Nutrition, the zinc absorption by people ages 59-86 was reduced by 50% when a calcium-containing supplement was given with the meal.


Gelatin is a tasteless substance created from collagen found in animal skin and bones. It is used to thicken liquid in processed foods as well as having applications in photography, cosmetics, and pharmaceuticals. Gelatin is found in many forms of candy, marshmallows, Jell-O, and some types of yogurt. Gelatin can be bought in many grocery stores for use in home cooking. In the vast majority of cases, gelatin is not harmful to the consumer.

Magnesium Stearate

Magnesium stearate is often used as a diluent in the manufacture of medical tablets, capsules and powders. In this regard, the substance is also useful, because it has lubricating properties, preventing ingredients from sticking to manufacturing equipment during the compression of chemical powders into solid tablets.

Magnesium stearate is the most commonly used lubricant for tablets. Studies have shown that magnesium stearate may affect the release time of the active ingredients in tablets, but not that it reduces the over-all bioavailability of those ingredients.
