2-FMA / 4-FA cross-tolerance?

[frontbluntt]

I took about 90mg of 2-FMA last night.
Tomorrow I want to have a good night off around 150mg of 4-FA
Will the 4-FA experience be affected? Should I take more than my normal dose?

yes there will be cross tolerance.

Do not take more than your normal dose, if you feel you need a top up sniff/plug a dose.
