The South African Institute for Drug-Free Sport (SAIDS) analysed batch 230524 of a supplement product named CPH4 Pre-Workout sold by a South African company named V-Pharma at a WADA-accredited laboratory, who confirmed the presence of 5-methylhexan-2-amine (1,4-dimethyl pentyl amine) in the dietary supplement. This ingredient is not listed on the label of the supplement, which is misleading to Athletes.
5-methylhexan-2-amine, also known as 1,4-dimethylpentylamine, is a substance that is Prohibited In-Competition under the World Anti-Doping Code (WADC) Prohibited List 20241. This compound is classified under S6.B Specified Stimulants, which means that its presence in an athlete’s urine sample would result in an anti-doping rule violation.
Given the detection of methylhexan-2-amine (1,4-dimethylpentylamine) in this supplement, Athletes are strongly advised to exercise caution when considering the use of dietary supplements, especially those that do not clearly list all ingredients. Methylhexan-2-amine (1,4-dimethylpentylamine) is a prohibited substance as per the WADC Prohibited List 2024 and is banned in-competition. Its presence in an Athlete’s sample, regardless of intent, will result in an anti-doping rule violation. The Strict Liability rule holds Athletes accountable for any prohibited substance found in their bodily specimens, regardless of how or why the substance entered their system.
The ongoing issue of mislabelling and contamination of dietary supplements presents significant risks to Athletes. Supplement manufacturing is not regulated in South Africa, therefore, SAIDS cannot guarantee nor advise athletes which supplement products are safe and free from contamination.
Athletes are encouraged to consult with a nutritionist or anti-doping expert before using any supplement, especially when in doubt regarding its contents and to:
Stay informed about potential recalls or warnings from SAIDS or other relevant authorities about contaminated or mis-labelled products.
Ensure you are familiar with the current WADC Prohibited List and understand the implications of consuming substances that may be banned in-competition.
Remain vigilant and aware of the risks involved in using dietary supplements, and to exercise caution when considering products that do not provide full ingredient transparency.
