Never used it (posted recently seeking first hand experience with it), it's supposed to be very good for strength and hardness: Halotestin
Halo is a no joke substance. This is one of the more dangerous substances out there, the only people I believe should be using it are powerlifters. I ran some back in the day prior to some wrestling matches...I was sweating, I was mad, had a slight fever, I was stong as hell, and I wanted to eat my opponent and spit him back out on the mat. Similar to Cheque Drops.
In terms of use in bodybuilding, the primary application of fluoxymesterone is for cutting cycles. Users often note improved muscle density and hardness when using the drug in the final weeks prior to competition. Since the compound does not aromatize there should be no concerns regarding water retention or bloat.
With fluoxymesterone, the majority of users have reported anecdotally that weight gain is minimal while on the drug, whether it be from water, fat or lean muscle. This can be a benefit to those athletes participating in sports that have weight divisions or where extra size and/or weight can be a hindrance.
The main reason most strength athletes and bodybuilders use fluoxymesterone is the dramatic increase in a user's strength while using the compound. Due to these increases in strength and the limited weight gain associated with the compound, fluoxymesterone has long been a favorite of powerlifters and those competing in sports where explosive strength is required.
Non-experienced users of fluoxymesterone anecdotally report taking doses between 20mg to 50mg per day. Cycles of the compound usually will be run for a maximum of six weeks, with four weeks being the norm due to the risk of liver damage. Due to the active life of the drug, two to three doses of the compound are required throughout the day to maintain stable blood levels of the compound. I believe the active life of the compound is just under 10 hours.
