This week I tried the Topical Deer Antler Velvet Serum by Pure Velvet. Just as a warning this product is very oily so you will want to wash your hands after and it has a strong smell from the extracts and oils. This serum is used to increase the range of motion and soreness of muscles. I have been using this after going to the gym and I have found that it has been helping to keep some of my problem muscles from getting stiff and sore. I am going to continue to try this while I get back into the swing of working out. Here is a picture of the serum after I have shook it up. The serum has a natural separation, so it has to be shook well before each use. I'm not sure is this is what it should look like or not, but I can confirm that I did shake it very well.
