Opinions - New Researcher Usage Safety Question

[Lymond]

My neighbor and his wife want to research the effect of methylone and have acquired 1 gram of the substance from a far away unknown source.

They have done much research and intend to start with about 125 mg each. They are worried though that no matter how much careful measuring they do, the substance could be something different than advertised. Their worst scenario would be that the substance is another RC that is effective at much lower dosages, say a substance that is effective at 5-20 mg (perhaps the supplier confused his shipments, etc).

They are worried because, while they both have enjoyed the more obvious RCs in the past, they both like light doses of the lighter substances.

Thus, even if they start at, say 50 mg, this would be WAAY too much if it is the wrong stuff.

These are nervous, middle aged people....

Any hints from the good people here would be very much appreciated....
