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").
Plant "anabolic" sterols (laxogenin, ecdysterone)
Laxogenin (5α-hydroxy-laxogenin) and ecdysteroids such as ecdysterone (20-hydroxyecdysone, from Ajuga turkestanica or Cyanotis) are plant sterols marketed as natural anabolic agents.
Milk thistle (silymarin)
Milk thistle (Silybum marianum) seeds contain silymarin, a mixture of flavonolignans studied for liver protection1.
N-acetylcysteine (NAC)
N-acetylcysteine (NAC) is a form of the amino acid cysteine and a precursor of glutathione, the body's main antioxidant. It is also used as a licensed medicine, for example as a mucolytic.
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.
Plant "anabolic" sterols (laxogenin, ecdysterone)
In a 12-week randomised double-blind training study, a commercial ecdysterone product gave no additional benefit over training alone, and its actual content differed markedly from the label2. In castrated rats, 5α-hydroxy-laxogenin showed neither androgenic nor anabolic effects3.
Milk thistle (silymarin)
A meta-analysis of randomised trials in people with liver injury reported improvements in some liver markers with silymarin4. These trials concern patients with liver disease, not healthy users.
N-acetylcysteine (NAC)
A meta-analysis found that NAC can raise glutathione levels after physical exertion, with mixed effects on other markers of oxidative stress and muscle damage5.
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.
Plant "anabolic" sterols (laxogenin, ecdysterone)
Label accuracy is poor and human trials are few2.
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 substances4.
N-acetylcysteine (NAC)
Effects on performance in healthy people are not established5.
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.
Plant "anabolic" sterols (laxogenin, ecdysterone)
Human safety data are limited.
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.
N-acetylcysteine (NAC)
NAC can cause nausea and digestive upset; people with asthma or taking nitroglycerin should ask a doctor first.
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 EU910. Anabolic agents are prohibited at all times by the World Anti-Doping Agency11.
Plant "anabolic" sterols (laxogenin, ecdysterone)
These plant sterols are not authorised novel foods in the EU10. Ecdysterone is on the World Anti-Doping Agency monitoring programme11.
