There is a difference between what is being sold as 20X and what a 20:1 (Full spectrum) extract is.
20:1 is given as the maximum extraction of all kratoms alkaloids, or a 'full spectrum' of alkaloids because when you take a certain amount of kratom
leaves and you extract all the alkaloids they can only ever weigh whatever weight they existed in to begin, where as what are marketed as X type extracts usually refer to the amount of kratom leaf used to make one gram of extract.
So a 20X extract sold by headshops is not a full spectrum extract, its final weight takes into account everything and not only the alkaloids that have been extracted.
20 grams of leaf are turned into 1 gram of resin. Aparently.
Most products sold as X extracts are usually basic water/alcohol
extracts, which are reduced to a resin and then sold in that form or powdered. They tend to be closer to about 3 times the potency per gram as plain leaf, but this will vary wildly.
The problem with the use of the X is that people take it as an indication of strength. But if you start with 100 grams of bad kratom and you somehow managed to turn it into 1 gram of extract (which outside of a lab is probably an imposibility) then your probably going to end up with a poor quality extract. Where as if you started with 10 grams of quality kratom and made the extract using the same process you would end up with a product that could be stronger han the supposed 100X.
Personally when it comes to 'Full Spectrum' extracts ive never been impressed. And most people would probably prefare a gram of an extract of one (or several) of Kratoms most active alkaloids than all of them.
By extracting select alkaloids you can still only get the 20:1 ratio, but by eliminating some of the alkaloids and concentrating on one or more you can make a more powerful extract, at least in the sense of the most notable effects.
Your body can only absorb a certain amount of anything. From the moment you ingest something untill its passed through you. If you take more than you can absorb then whats left will come out, without being too graphic about it
A lot of the high potency products being sold are made using extracts produced in China.
Personally i dont think they are worth the prices they are sold as and i would be concerned that many contain more than just Kratom alkaloids.
They are best avoided by anyone who intends to use kratom regularly as they will raise your tollerance dramatically making regular kratom leaf ineffective at regular doses and they will bring on a far nastier addiction
which many people have reported to be every bit as bad as other opiate
I would personally like to see these strong extracts and enhanced products removed for sale as i think they risk kratoms continued legality in the remaining countrys where it still is legally sold.
