5a-Hydroxy Laxogenin was discovered in 1996 and shown to have an anabolic/androgenic ratio similar Anavar, but without the side effects of liver toxicity or testing positive for steroidal therapy. Athletes claim to have seen strength increases in 3-5 days, and muscle mass increases in 3-4 weeks. 
AKA Laxogenin

5a-hydroxy-laxogenin is a steroidal sapinogen, although whether or not it is the desired laxinogen is a mystery since no lab standard for it is available, nor was it referenced within the GCMS library.

Marketing claims for this compund say it is the only product ever designed to increase mass and strength without steroidal influence and that it doesn't test positive for steroids. 

Tests showed that protein synthesis increased by over 200%, the key to lean muscle growth and accelerated repair. In testing, 5a-Hydroxy Laxogenin has balanced cortisol response, which is the major cornerstone to healthy recovery and reduction of muscle wasting. 

It's also been shown to balance cortisol on calorie restricted diets, helps control glucose and increases thyroid function.
