Purity - Is this GHB safe?

[jjim]

SWIM was unsure about making his own so he bought some through AFOAF and it came in a plastic tub as a white ground up soapy looking solid which he was told to dilute with boiling water and he noticed it was very uncomfortable on his throat, smelled salty/chemically, generally tasted rank, and caused some stomach pain, besides the anticipated positive effects. He decided to test the ph but was only able to obtain litmus test for acid and it appeared to be acidic. He thinks it may contain some unreacted GBL? Is there a simple way to neautralise the solution and make it a bit less harsh?
