Scientific background

Independent research

Prohormones 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").

Vitamin E (α-tocopherol)

Vitamin E is a fat-soluble antioxidant. EFSA set adequate intakes of 13 mg a day for men and 11 mg a day for women, as α-tocopherol¹. Vitamin E TPGS is a water-soluble form used as an ingredient and absorption enhancer.

Research evidence

Independent research

Prohormones 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.

Vitamin E (α-tocopherol)

The EU authorises the claim that vitamin E contributes to the protection of cells from oxidative stress². Benefits of high-dose supplements beyond meeting needs are not established.

Evidence limitations

Independent research

This 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 uncertain³⁴.

Vitamin E (α-tocopherol)

Most people in the EU meet their needs from food¹.

Safety & potential risks

Independent research

Prohormones and designer anabolic steroids

Case reports describe drug-induced liver injury, including cholestasis, from prohormone and bodybuilding supplements containing anabolic-androgenic steroids³⁴⁵. Anabolic steroids also suppress natural testosterone production and adversely affect blood lipids and the heart.

Vitamin E (α-tocopherol)

The EU Scientific Committee on Food set a tolerable upper intake level of 300 mg a day for adults⁶. High doses may increase bleeding risk in people taking anticoagulants.

Regulatory status

GIGACULT product information

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.

Regulation and sport

Prohormones and designer anabolic steroids

Anabolic-androgenic steroids are medicinal substances and are not permitted in food or food supplements in the EU⁷⁸. Anabolic agents are prohibited at all times by the World Anti-Doping Agency⁹.

Vitamin E (α-tocopherol)

It is a permitted nutrient in EU food supplements¹⁰; authorised claims may only be used in their approved wording and when the product is at least a source of the nutrient².
