Quote from: mslix on January 30, 2013, 01:07 pmlittle time, but interesting question. First of all: racemic means a perfect 50:50 mixture of both enantiomers (dextro and levo). I first read this in a scientific paper where researchers treated coke addicts(??) with d-amph: they analyzed the urine and if they found some l-amph they knew that the test subject did street-speed (simplified). They also analyzed the speed samples and found that a lot of them were not racemic, but could be off by up to 20% in their respective d/l-enantiomer ratio. They also concluded that this was caused by the manufacturing process. So depending on how and with what precursor it was made the d/l-ratio might change. If it's high on the l-enantiomer side, it should give in theory more of a body rush than some amph-sulphate that's racemic or high on the d-side. Another factor that might be at play here are the impurities that are introduced during manufacture and are characteristic for a certain precursor and process ("impurity-profiling"). With the amph as "carrier" (so I have read) those could cross the BBB more easily and be active in much smaller amounts. Most of these are only researched in respect of how and where they get in to the amph, not what effects on the human they might cause. Only if you manufacture 99.999% pure amph you can be absolutely certain that none of these factors are at work. So to answer the question: unless pharma grade (99.9%) it's possible that different routes of manufacture will yield different products and hence have different effects. Another extremely important factor is the psyche. My rough estimation is that 60-80% of reports on varying (side)effects are caused by differences in set&setting, perception (of the product) and expectation. Happens that I was among those who coined the connection "BM has body-load", but it was never meant the way it is interpreted now. The term is often used for negative or positive body experience (yes, also by native speakers), but some use it only to describe the negative side. This took over and carried on until now. For me this is somewhat funny to watch, as everyone just assumes from the early reviews that there will be unpleasant body-load when most reviews actually never suggested that, when read in detail. Point is: placebo-like effects will change your perception of the experience probably the most. People who expect body-load (e.g. rapid heartbeat, high blood-pressure) will get it. Amph-Sulphate just does that to the body. No way around it. But expecting it often means noticing it more. IMHO: subtle changes can be triggered by subtle differences in the product, but your head is where the experience changes.The waxy part can be washed out, at best it's actually still freebase (pure amph). At worst it's a byproduct of manufacture.Muslix you beautiful son of a bitch, I could fucking kiss you. If you had any goddamn idea how long I've been on the look out for precisely what you have just given me -- years... literally. Never made it enough of a point to really research it, but I've always wanted an answer, and by God you've just given me at least a working theory. Cheers mate.Also, your appraisal of BMs purity vs. CCs feels (speaking from a purely subjective standpoint, mind you) almost spot on. BMs stuff has always felt amazingly potent to me. Noticeably moreso than CCs current stock. With that said, I still strongly prefer CCs product. BMs stuff just doesn't give me what I want. It gives me everything I don't and almost nothing that I do. CCs may be less potent in the end, but at least I can rely on it to get the job done.P.S.- Regarding the corepharma adderall thing, they do not put refined sugar in their adderall, hence it's more bitter taste. Yes, Barr for example puts actual sugar in adderall to make it taste better.
