Prohormone supplement 3ß-hydroxy-5α-androst-1-en-17-one enhances resistance training gains but impairs user health.

Prohormone supplements (PS) are recognized not to impart anabolic or ergogenic effects in men, but the research supporting these conclusions is dated. The Anabolic Steroid Control Act was amended in 2004 to classify androstenedione and 17 additional anabolic compounds as controlled substances. The viability of PS that entered the market after that time have not been evaluated. Seventeen resistance-trained men (23 ± 1 yr; 13.1 ± 1.5% body fat) were randomly assigned to receive either 330 mg/day of 3ß-hydroxy-5α-androst-1-en-17-one (Prohormone; n = 9) or sugar (Placebo; n = 8) per os and complete a 4-wk (16 session) structured resistance-training program. Body composition, muscular strength, circulating lipids, and markers of liver and kidney dysfunction were assessed at study onset and termination. Prohormone increased lean body mass by 6.3 ± 1.2%, decreased fat body mass by 24.6 ± 7.1%, and increased their back squat one repetition maximum and competition total by 14.3 ± 1.5 and 12.8 ± 1.1%, respectively. These improvements exceeded (P < 0.05) Placebo, which increased lean body mass by 0.5 ± 0.8%, reduced fat body mass by 9.5 ± 3.6%, and increased back squat one repetition maximum and competition total by 5.7 ± 1.7 and 5.9 ± 1.7%, respectively. Prohormone also experienced multiple adverse effects. These included a 38.7 ± 4.0% reduction in HDL (P < 0.01), a 32.8 ± 15.05% elevation in LDL (P < 0.01), and elevations of 120.0 ± 22.6 and 77.4 ± 12.0% in LDL-to-HDL and cholesterol-to-HDL ratios, respectively (both P < 0.01). Prohormone also exhibited elevations in serum creatinine (19.6 ± 4.3%; P < 0.01) and aspartate transaminase (113.8 ± 61.1%; P = 0.05), as well as reductions in serum albumin (5.1 ± 1.9%; P = 0.04), alkaline phosphatase (16.4 ± 4.7%; P = 0.04), and glomerular filtration rate (18.0 ± 3.3%; P = 0.04). None of these values changed (all P > 0.05) in Placebo. The oral PS 3ß-hydroxy-5α-androst-1-en-17-one improves body composition and muscular strength. However, these changes come at a significant cost. Cardiovascular health and liver function are particularly compromised. Given these findings, we feel the harm associated with this particular PS outweighs any potential benefit.

Safety and activity of the immune modulator HE2000 on the incidence of tuberculosis and other opportunistic infections in AIDS patients.

Twenty-five AIDS patients were treated with HE2000, a synthetic adrenal hormone. The drug was well tolerated and safe and reduced both the incidence of tuberculosis coinfection by 42.2% (P < 0.05) and the cumulative incidence of opportunistic infections (P < 0.05). These results warrant further clinical investigation of HE2000.

Reduction of parasite levels in patients with uncomplicated malaria by treatment with HE2000.

16alpha-Bromoepiandrosterone (HE2000) is a synthetic androstane steroid that has immune effects in pre-clinical models of malaria, tuberculosis, and infection with human immunodeficiency virus. In pilot studies, 42 patients with confirmed uncomplicated Plasmodium falciparum malaria were treated with a seven-day course of HE2000 by either buccal administration or intramuscular injection. Of the 42 patients, 41 showed a 50% reduction in blood levels of parasites, the primary endpoint of the study. Of these, 32 (76%) cleared malaria parasites below detectable levels. All febrile patients became afebrile by the end of treatment. There was no reduction in gametocyte forms. Adverse events were transient and mild to moderate in intensity. The anti-malarial response was generally similar with either the intramuscular or buccal routes of administration. HE2000 shows a safety profile and pharmacologic activity worthy of further investigation to understand its role in the treatment of malaria, perhaps in combination with anti-malarial agents.
