Notes Promicrol is considered by many to be one of the best speed-increasing developers ever made. Sadly one of its key ingredients 2(beta-hydroxyethyl) aminophenol sulphate (aka HEAP sulfate) is no longer in production anywhere in the world. Current commercial products sold under the name Promicrol or claiming to be similar to Promicrol are not comparable to this formula. |
