Scientific background
Independent researchProhormones and designer anabolic steroids
Prohormones and "designer steroids" are synthetic anabolic-androgenic steroids, or precursors converted to them in the body, sold in supplement-style products. Examples include methasterone ("Superdrol"), methylepitiostanol ("Epistane") and trendione ("Trenavar").
L-arginine and AAKG
L-arginine is an amino acid used by the body to make nitric oxide. AAKG is arginine bound to alpha-ketoglutarate.
Uva ursi (bearberry leaf)
Uva ursi (bearberry) leaf contains arbutin, which is converted to hydroquinone, and is a traditional remedy for urinary tract complaints.
Milk thistle (silymarin)
Milk thistle (Silybum marianum) seeds contain silymarin, a mixture of flavonolignans studied for liver protection1.
Research evidence
Independent researchProhormones and designer anabolic steroids
No controlled trials support the safety of these products. Their muscle-building effect derives from anabolic-androgenic steroid activity, the same mechanism as controlled steroid drugs.
L-arginine and AAKG
A dose-response meta-analysis of randomised trials found that L-arginine lowered blood pressure in adults2. Evidence for improved exercise performance or "pump" is inconsistent; oral arginine is extensively broken down before reaching the circulation, which is why citrulline is often preferred3.
Uva ursi (bearberry leaf)
A risk assessment concluded that, under the recommended use conditions for herbal medicines, uva ursi leaf is a safe option for treating lower urinary tract infections4.
Milk thistle (silymarin)
A meta-analysis of randomised trials in people with liver injury reported improvements in some liver markers with silymarin5. These trials concern patients with liver disease, not healthy users.
Evidence limitations
Independent researchThis product does not state all ingredient amounts, so the doses used in research cannot be compared with what one serving provides.
The studies summarised in this guide examined single ingredients. No published study has tested this product or this combination of ingredients.
Prohormones and designer anabolic steroids
Products are often mislabelled or adulterated, so the actual steroid and dose are uncertain67.
L-arginine and AAKG
Studies vary in dose and population2.
Uva ursi (bearberry leaf)
Its use is short-term and medicinal; it is not studied as a daily supplement4.
Milk thistle (silymarin)
Trials vary widely in preparation, dose and patient group, and do not show that silymarin prevents liver damage from drugs or other substances5.
Safety & potential risks
Independent researchProhormones and designer anabolic steroids
Case reports describe drug-induced liver injury, including cholestasis, from prohormone and bodybuilding supplements containing anabolic-androgenic steroids678. Anabolic steroids also suppress natural testosterone production and adversely affect blood lipids and the heart.
L-arginine and AAKG
A risk assessment identified an observed safe level of 20 g a day9. Because it lowers blood pressure, people taking blood-pressure or erectile-dysfunction medication should ask a doctor first2.
Uva ursi (bearberry leaf)
Uva ursi should only be used short-term because of hydroquinone exposure, and not in pregnancy, breastfeeding or kidney disease4.
Milk thistle (silymarin)
Silymarin is generally well tolerated and has few drug interactions, but caution is advised with medicines that have a narrow therapeutic window; safety in pregnancy is not established1.
Regulatory status
Contains synthetic anabolic-androgenic steroid compounds or prohormones. These are not authorised as food (including food supplements) or as medicinal products in the EU and are on the WADA Prohibited List. No dosing information for human use is provided.
Prohormones and designer anabolic steroids
Anabolic-androgenic steroids are medicinal substances and are not permitted in food or food supplements in the EU1011. Anabolic agents are prohibited at all times by the World Anti-Doping Agency12.
L-arginine and AAKG
No health claim for this ingredient is authorised in the EU13; botanical ingredients are sold under national food-supplement rules14.
