Please do not take any unidentified pharmaceuticals that were sold as "heroin". With the information provided, which is next to nothing, I searched imprints of bi-scored pink pills and found nothing conclusive because the OP didn't include any imprints on this mystery pink double-scored tablet.
With the current information, we can do nothing but speculate so I'm going to close this. You can find out what your pill is by using the website I already posted in this thread, or google search/images based on what you see (shape of pill + color of pill + imprints on pill)
