Natural plant-based steroids originate
from Smilax Sieboldii
Smilax Sieboldiiis a climbing shrub which mainly grows in East Asia, and South and North America [1]. Its young leaves are used for food and the subterranean parts have been used in Traditional Chinese Medicine (TCM) for arthritis, tumors and lumbago [2, 3]. This plant has aroused researches tremendous attention because of a natural steroidal sapogenin-laxogenin [4]. Laxogenin is a spirostanic analogue of brassinosteroid, shown to possess an anabolic/androgenic activity similar to one of the most efficient anabolic substances, anavar, yet without the side effects of liver toxicity or likelihood of testing positive for steroid .
What is Laxosterone®
Laxosterone® is the trademark of PURE LAXOGENIN 100% from SYNMR BIOTECHNOLOGY (SHANGHAI)LIMITED. Due to very less content in nature plant, we create a green bioconversion method to get a highly purified PURE LAXOGENIN 100% from nature plant materials. Meanwhile, we developed a new microencapsule 5α-Hydroxy Laxogenin, with very good bioavailability.
Highlight of Laxosterone®
However, its application was blocked by a surge of fake raw materials since 2010. We have tested different origins of PURE LAXOGENIN 100% from the market, content are all very low, only from 20-55%, even some are not PURE LAXOGENIN 100% at all.
Exclusive agency in Brazil
We have exclusively authorizes the Brazil company PHD COMÉRCIO IMPORTAÇÃO & EXPORTAÇÃO LTDA to sell our Laxosterone® in Brazil market. Period of exclusive Authorization:
【Five】Year, from 2017.10.23 to 2022.10.22.
Benefits of Laxosterone®
According to a Russian research, PURE LAXOGENIN 100% could accelerate the gain of weight in rats by increasing the weight of the liver, heart, kidneys, musculus tibiliasis anterior and augmenting the total amount of protein therein as well. All of the above-mentioned changes become more pronounced with the study substance introduced to young animals [5].
Date also indicated that PURE LAXOGENIN 100%, used by athletes, produced dramatic strength increases in 3-5 days, and muscle mass increases in 3-4 weeks. The increase of protein synthesis by over 200% was the key to lean muscle growth and accelerated repair. Further investigation of the molecule showed that it could also balance cortisol response which is the major cornerstone for recovery and reduction of muscle wasting.
