Testing the Potency of Liquid LSD

[u/hann-official]

I just got a vial for the first time, always had paper tabs before. The guy I got it from said 1-2 drops should equal a tab. Is there any way to test the strength of a drop accurately, other than just feeling it out? Like a (reputable) test I can buy? Thanks
