++I ordered six bottles of synapse xt for relief from my tinnitus, at a cost of $314.14. Emailed the vendor asking for a refund. They ignored my request, so the time for the refund ran out. I consumed the product for two months as directed, now I have more noise no relief and am out my money. Please do not buy from this shady company. buy from this shady company User's recommendation: Do NOT seek relief using ripoff Synapse products .
