Labmax testing "purity"

I'll stick it in my ass and let you know how it labmaxes in 3-4 weeks :cool:
That time I was in your ass, 6 minutes felt like an eternity, I'm not sure a diamond could survive 3 weeks in there. We need a new form of testing, your ass is out.
 
I'd be willing to send some stuff I've brewed but not wasting my money on labmax. According to their own site, their tests do not test for purity so anyone who claims they do is either shilling or smoking some good good

The test will not give you exact concentration but this is what the instruction says:

The idea is to drop as small amount as possible and bright fluorescence will indicate that it is good sample. In some cases it can give you some idea about the concentration of the hormone but this test was not designed for this type of analysis and it is not tool for this purpose.

it is right here http://www.labmax.ca/instruction.php but people never read this

So you will see difference between crap and pharma grade

And immediately after in your quote it says

"but this test was not designed for this type of analysis and it is not tool for this purpose."

do I really have to explain every sentence ?

you do not know if it is 200 mg/ml or 150 mg/ml, it does not test for this

but it shows you difference good pharma grade or crap

I have seen it many times as Wunderpus stated when he tested his Watson

So you're claiming to explain something that goes contrary to what their own website even states? Are you the lead developer of labmax?
 
Baytch.
I don't play when the vial says 100 mg
I can say till blue in the face.
Means nothing all Ivan go by is the people who test it.

That is because LE is merely looking for the presence of cocaine itself...and their lab will do a quantitative analysis on it anyway. Ive done plenty of marquis reagent tests myself and if given two approximately equal amounts (think specks) and dropped two equal size drops of reagent liquid onto the substance...its very possible that, say in the case of methamphetamine, one will turn half or just some of the reagent liquid orange, and slowly turn to reddish brown, whereas the other instantly permeates the entire reagent drop with a very intense reddish orange and reacts quickly turning it reddish brown faster and and with more color intensity. Does this quantify anything? no, but it certainly allows you to set some kind of standard to look for in others. Of course, it takes testing many samples to develop the picture of quality this way.

But they do make cocaine tests that give relative purity in this manner- called EZ test white.
 
But to this topic- Id personally never use it to give an indication of purity unless i was using it on powders, and had already used it on powder that had I an assay done already. That and, Id have to know more about the test. What is it reacting with to turn that color...and how do I know that the powder isnt adulterated with another lower cost powder that the test would also react with in the same manner to give the illusion of higher purity..

Im just a guy who was a UG lab here at Meso back in the early 2000's (proline/Gmunk day-if anyone was around then) and on for 5 or 6 years.... so take it FWIW.

Those type of tests are called semiquantative and for all intents and purposes serve no purpose in the field. That's bc the focus is to ensure a true positive is exactly that a positive. PEOPLE DON'T LIKE GOING TO JAIL BC SOME TEST IS INACCURATE!

(Also know these tests MUST be simple to use, calibrate and generate reproducible results and assays that try to evaluate a products concentration are more difficult to use, require training and their ability to generate reproducible data is often OPERATOR DEPENDENT
something defense attorneys LOVE!)

Nonetheless this form of assays use a KNOWN quantity of reagent and a cofactor to "bind" the suspect drug to. The amount of "binding reagent" used, or the magnitude of an expected color change especially if it "falls" into another spectra indicates a greater quantity of product, BUT they CAN NOT quantify a specific amount present, as in mg/ml

Additionally those tests are notorious for reacting with chemically/structurally similar compounds and THAT is the problem with such testing.

The bottom line is whenever the sensitivity of an assay is increased the specificity is ALMOST always decreased and vice versa. The exception is VERY EXPENSIVE, technologicvally advanced, and difficult to operate analytical equipment!

Yep...I agree with all of that, I must have quoted the wrong post when he mentioned police using reagent tests, that the color is the same regardless of how cut it is... so I wanted to clarify that point regarding reagent tests and that they can indicate more than just presence only.....but clearly nothing quantitative...which is why they are presumptive tests.
 
I have played with testing different concentrations. I never posted about it because the results were useless.

I tested 3 different concentrations of t-e for 2 different raws (6 total tests) that I have HPLC results for from Capt. Forest. I tested 5%, 20% and 100% concentration of the hormone for each raw. The difference in brightness was more pronounced between the different raws than between the different concentrations.

In fact, the raw with the dimmer glow had no detectable difference in brightness between 5% and 100% concentration. The raws that produced the brighter glow had a detectable difference between 5% and 100% concentration, but not enough to say one was good and the other bad.

Like Merc's quote says, "in some cases...". The problem is you have no way of knowing when that rule applies. Suffice to say a bright result is more likely to be properly dosed than a dim result, but how much more likely is absolutely indeterminate.

I have noticed over the years that good pharma grade gives more vivid, bright colors compared to some crap with very low dose

with some experience in testing you know that you might have something really good.

there seems to be a lot of experts on LM, who actually never used this test
