Buckpower antler velvet

Patient: Hello,I am 18 years old and just purchased some Buckpower antler velvet extract. It is a dietary supplement that is supposed to make you stronger and healthier in general. However, I compete in track and field and triathlons on the national level and we are occasionally, but rarely, drug tested and i am afraid it might be a banned substance. If it is banned, is it detectable in a drug test or could i take it through January and stop if my first big competition is in March and be okay? Thankyou for any information.
