The common side effects of oxymetholone include depression, lethargy, headache, swelling, rapid weight gain, priapism , changes in skin color, urination problems, nausea , vomiting , stomach pain (if taken on an empty stomach), loss of appetite, jaundice , breast swelling in men, feeling restless or excited, insomnia , and diarrhea .  In women, side effects also include acne , changes in menstrual periods , deepened voice, hair growth on the chin or chest, male pattern baldness , enlarged clitoris , and changes in sex drive .  Because of its 17α-alkylated structure, oxymetholone is highly hepatotoxic . Long term use of the drug can cause a variety of serious ailments, including hepatitis , liver cancer , and cirrhosis ; therefore periodic liver function tests are recommended for those taking oxymetholone. 
Oxymetholone is as mentioned very hepatic and liver enzymes will necessarily increase dramatically with its use. For this reason most Oxymetholone use will generally need to be kept at 6 weeks max with many never needing to go beyond 4 weeks of total use. While this is a very short lived duration its important to note, Oxymetholone appears to be one of the few steroids that really diminishes after use is extended; meaning, even if you went past the 6 week mark you probably wouldnt get much out of it other than damaging your liver. It is comforting to note, while it is toxic to the liver, when used responsibly any toxic effect will be of little concern as the liver will quickly return to normal once use is discontinued. It is important to note, as this steroid is hepatic it does not carry near the level of hepatotoxicity as many over the counter medications and regular alcohol consumption.
Before coming to Eindhoven, I studied metal craftsmanship at Ecole Boulle. This school teaches students the traditional French craft heritage. There, I learned to have a good vision in 3D, precise technical skills and an eye for quality. Some aspects of this education have remained strongly in my mind: as we were forging our own tools with a fire torch and a hammer, I designed my own tools -all laser cut in steel- to construct the ‘Regen’ garments and accessories. I also love all the little technical tricks that make crafts and techniques being so smart. And to conclude, I really enjoy the craftsman routine: spending time in an atelier, being physically active and focused, trying out different tools, making a mess, and having the greatest satisfactory feeling when all the products are finally done and the atelier is clean again.
What fascinates you about designing materials?
First of all I would say that I am a materialist and therefore, I like to touch and feel the matter. I like the weight, the texture and the smell of things. I feel connected to the materials because my senses can relate to them. I like the smell of Argon when I weld, the smell of sheep when I work with wool, the smell of latex when I work on ‘Regen’. All these details give an atmosphere to my days. Besides this, I am seeking unexpected outcomes from common materials. I enjoy playing with their limits, or combine them to extract possibilities they haven’t given yet. When I manage to get a surprising effect, then I feel that I have achieved my goal.
