Study, Trial or Testing Result Summary

No study in people has tested androst-3,5-diene-7,17-dione for male hormones, and none of the studies found tested this exact ingredient. The daily amount in this product is listed as 75 milligrams, but how that relates to any studied dose is unclear. In a 2017 rat study, a different but related hormone-blocking compound raised testosterone, but it did not improve depression-like behavior or stress hormone levels [1]. In a 2015 study, two horses given a single 800 milligram dose of a related hormone-blocking compound had higher testosterone in their urine, and the compound could be traced in urine for about three days [2]. Two studies in about 20 castrated male monkeys over roughly three months combined male hormones with hormone blocking and looked only at brain chemistry linked to serotonin, without measuring any hormone benefit that applies to people [3][4]. Taken together, these studies do not show whether this ingredient helps male hormones in people. The product is popular with buyers, but the research behind it is very thin. Animal and cell studies are never counted.

Customer feedback and discussions surrounding supplements containing Androst 3,5-dien-7,17-dione, the active ingredient in BMM Supplements ARIM-EX, reveal several qualitative themes regarding its perceived effects and utility. A recurring sentiment among users is its role as an aromatase inhibitor (AI) to manage estrogen levels, particularly during or after cycles of other performance-enhancing compounds. Many users report that the supplement effectively helps in reducing water retention, contributing to a "drier" and "harder" muscular aesthetic. Some individuals have noted a tangible hardening of their muscles after using compounds with this ingredient. However, the perceived strength and efficacy of Androst 3,5-dien-7,17-dione as an AI are subjects of varied opinion. While some consider it a useful tool for "mild cycles," others describe it as a "mild to low AI" or question its overall effectiveness, suggesting it might be "debatable" compared to prescription-strength alternatives. This leads to a common theme where experienced users often advise having a stronger, prescription-grade AI on hand as a backup, especially if relying on it for significant estrogen control. Beyond estrogen inhibition, a notable qualitative theme is the compound's potential for cortisol reduction. Users appreciate this aspect for its contribution to overall stress management and potentially improved body composition. Despite these perceived benefits, concerns are frequently raised about the broader implications of AI use. Discussions often touch upon potential negative impacts on cholesterol levels, bone density, libido, and general mental well-being, prompting users to weigh the benefits against these risks. The product's specific warnings against use by women and tested athletes (due to WADA and NCAA prohibitions) are also important considerations in the user community. Overall, while many users find value in its estrogen-reducing and drying effects for physique enhancement, there is a clear understanding that its potency is moderate, and careful consideration of potential side effects and individual needs is paramount.

RAL Summary
Members OnlyTier 4 for Hormone Balance for Men
The tier claims animal studies support this ingredient, but every study cited tested a different, related hormone-blocking compound or measured nothing relevant to male hormones, so there is no study support for this exact compound. So it is graded Tier 4, lower than the rules alone gave.
- Emerging: not enough evidence to rank higher yet.
Where the evidence disagrees: 1 of the 4 human studies found no effect.

Body systems: Endocrine system, Reproductive system
Combine with: To synergistically support hormone balance and overall male health, consider combining ARIM-EX with supplements like Zinc, Magnesium, and Vitamin D, which are crucial for testosterone production. Additionally, DIM (Diindolylmethane) or Calcium D-Glucarate can further aid in healthy estrogen metabolism and excretion, complementing the aromatase inhibiting effects. For general vitality, adaptogens such as Ashwagandha may also be beneficial.
Possible side effects: No major side effects were reported in the studies. The review summary mentions user concerns about cholesterol, bone density, libido and mood with hormone-blocking use, though no written reviews were read directly.
