what is the brand of dxm you take? i find desylm to just make me feel drunk, and hbr usually is alot more trippy to me
There is no such thing as a "brand" of DXM. That's as asinine as brands of cocaine or brands of MDMA or brands of PCP. A chemical compound either is or is not, but there are no brands nor some existing continuum of is-isn't for unadulterated chemical compounds.
However, in medicinal chemistry, pharmacology, pharmaceutics, and any topically related scientific bailiwick, there are what are known as pharmaceutical formulations. A simple and succinct definition of a formulation (in this context) would be a pharmaceutical or chemical entity that is combined with other chemicals (excipients) for legitimate medicinal/pharmacological purposes and/or as a kind of marketing artifice or guile.
An example of a common pharmaceutical formulation on the market would be codeine + acetaminophen. A more germane example is DXM + acetaminophen or guaifenesin.
Any pharmaceutical that does not solely ccontain a single active constituent, or possesses at least 1 inactive ingredient, or both is a formulation. (However, the existence of inactive ingredients is usually not considered, but only the active ingredients). These formulations are presumably what you meant or had in mind when using "brand".
So, why is my saying all this not just pedantic, inconsequential, jejune nitpicking? Because the thread is supposed to be about DXM and its effects. Therefore, it's irrelevant to question whatever effects whichever ancillary chemicals in the formulation produced.
Moreover, the OP had already made it pretty clear that he had used a product with DXM as the only active ingredient (thereupon rendering any discussion of "brands" (i.e, formulations with other active ingredients) off-topic and pointless) when he says thus:
Also, the only active ingredient in the cough syrup was DXM.
Additionaly , DXM's psychotropic effects vary only moderately between individuals, with the experience being essentially the same for most people. It's only the opinions or value of the experience that varies markedly from person to person. In other words, the preference one has or the quality they impute to the drug. For example, the difference between people who dislike alcohol and those who do not isn't an issue of pharmacology, but of preference and palatability.
Therefore, a product containing only DXM will produce the same or similar effects as another DXM-only product, regardless of brand. Just like pure MDMA has the same effects whether it's called x, ecstasy, molly, XTC, mandy, E, and so forth.
