Recently, I was able to come into a bottle of tussionex pennkinetic. Regarding recreational use, what is the appropriate amount to maintain a solid buzz? I am nervous of the use due to the Chlorpheniramine contained in the product. Additionally, I am used to the purple and not this yellow. Whats the main difference and again, what dosage should I be using to be in a good spot without pushing the limit to extreme dangerous cutoffs? Thanks.
