BE AWARE !!
Be aware of companies that sell anything over 300mg's per ml, first off you cannot make a product with much over that amount, the active raw material just doesn't fit, also when you get over 250mg's per ml you are going to get a lot of scar tissue in your injections and these higher concentrated shots will be very painful!
This is why real pharmaceutical companies never go above 250mg's per ml. So don't waste your money, they are scamming you and your just going to end up with a lot of large sore lumps of scar tissue!
