Be careful, because the company www.stemologica.com is big scam and rip off. I haven’t opened this website and haven’t purchased from them. However, these guys somehow found my card information and used it. They charged me for $129.99 and I have no idea for what really. I emailed the seller, but he of course ignored the message and no one returned this sum back. I really hope that this company would be shut down soon.
