+ 28 Mass Spec Explained~Sleight of hand exposed

ad

It is time for a little education on mass spectrometry testing, I hope you all find it useful and for those that don’t perhaps you’ll find it interesting. I will keep it as simple as possible without getting too technical.

There are several different types of testing in the mass spectrometry world and we are gonna focus on two for right now. They are the most common results that we see here on this site. They are the HPLC Column test and the Spectrum test. While each one has its purpose and is useful in its own way, without being applied correctly they can be very misleading. At the heart of these tests is the molecular weight of the compound being tested. The spectrum test identifies all the ions within a sample based on their molecular weight within a predefined range. 0-800m/z is the range that all anabolic steroids fall between with the oil, BA, and BB being outside that scope. The molecular weight of the target compound is compared to a known sample to verify the compound is present. Once that is verified we take the quotient of the target compound (X) and the total of unknown ions that make up all the other molecular weights (Y) to arrive at a purity (X/Y). The density of the target compound relative to the suspension is again compared to a known sample to verify if the correct dosage has been made. While that measurement is accurate, it cannot be exact. That is more of a function of the HPLC column test.

The HPLC column test differs from the spectrum test in that it separates all the ions that pass through it and separates them into different groups where it then tests the purity of that individual group. This process is extremely useful for identifying an unknown substance in a compound, as well as it is very precise for showing a dosage. It does not calculate the amount of target compound compared to the other substances in the sample, therefore, the purity calculation that it performs is only on the target compound. (When I say target compound I am referring to the one that we are most interested in such as test or tren.) This purity percentage is very misleading since people think that it is an overall purity, which is not true. To oversimplify it:

Full Spectrum Testing: 10 people in a room, 2 blondes, 8 brunettes = 80% brunettes
HPLC Column testing: 10 People in a room, 2 blondes, 8 brunettes. 2 blondes are put in a different room and now = 100% brunettes.

Now that all that has been defined I get a lot of PM’s from people and sources that are excited because they just got an amazing find from a standup guy in China that wants to send them 99.9% pure raw material and has tests to prove it. When that raw material is put through the spectrum test they are always disappointed in the results, and rightfully so because they were sold on the idea that they had ultra-pure raw material. The problem is that our friends in China are running the HPLC column test, which we know isolates the target compound and then tests it for purity, and are selling it as a full spectrum test. You can spot a column test easily enough because the purity is always 98-99.9% pure. That isn’t to say that 97% isn’t possible with a spectrum test because we have seen that once or twice, but it is very rare.

So the moral of the story is that if you are in the market for raw material and you are being sold a Ferrari at Hyundai price, you might scrutinize the proof a little. Then take your newly gained knowledge and wield it so that you don’t become a victim.

People here on eroids seem to have a lot more faith in blood work than mass specs, at least as far as TE/TC are concerned.

Roid Noid's picture

I will put in a couple cents of thought on this thread, I know diddly squat about mass specs, how they work, who is right and wrong, beats me. Eroids is a platform designed to protect members, not sources! So me personally when i see sources getting mass specs done, thats great and all but i dont believe it. to easy to send in a raw that they know is good and then use another to make their oils. while there is a couple of sources on here that i would trust, my experience and the information we have have on hand shows that most are not trustworthy.

with that being said when i look at mass specs the only ones I care about are the ones that are sent in by users to be tested.

there has been plenty of questions floating around about angus getting paid off by sources to protect them, and I can see where that can come into play and why people would think that. So how do we get around that?

my suggestion to any member sending in a sample for testing is to take off the label and color it, letter it, number it, whatever but make it so only you can match the corresponding icon to the source. so you get email mass specs for vial #1, you match that to proper source and product.

that would alleviate much of the suspicion.

maybe even angus for your own good suggest anyone sending in multiple samples to do this.

Excellent points!............. may i add if a restaurant sold shit food over and over what would happen!... yep folks quit going there and the fucker goes bankrupt!.... if folks quit spending things MUST change, either for the better or sources crumble.

iFit's picture

Agreed with all your points. Would also be nice to have the results easy to sort by source, date, results, product, user/source submitted, etc. From what I see, the way it works now, sources that post good results get a fast bump in sales but it slows down because people forget. Same holds true for bad results, sales will tank for a while until it goes to the "2nd page".

I do not want to discredit Angus honestly. He still can modify his testing methods and I will be the first one the back him when he will do. At the moment I presented only facts.
I do not ask anyone to believe me, would be stupid. Do not believe me please believe logic and mathematic. Until now Angus logic and mathematic failed.

Maybe because he is a middleman and he doesnt communicate good who knows. In order for this analyses to be credible he need to change the methods ( even continue using MS ) and provide more informations.

I just need to get to the bottom of this shit............ SOMEONE is running the board! and it definitely is NOT the MODS at this moment in time.

CBBurrr's picture

So the primary question here is : can a steroid dissolved in an oil be tested for purity, and if so how?

If we get a mass spec chart in the m/z format and remove the known results for oil, BA, BB, and the target steroid, everything else is an impurity, correct?

HERE FOR THE BEGINING YOU HAVE A ANSWER FROM THE CHEMIST WHO WORK WITH THE PROFESSOR.

This answer is a reply to this post here named "Mass Spec Explained~Sleight of hand exposed"

If you look closely through your post "Mass Spec Explained~Sleight of hand exposed" , you will find the description of mass spectrophotometria method. This method may be used for the identification of an unknown substance (or substances) in a mix of substances, only if being guided by the standard which in most of the cases is a part of the equipment’s database.
Mass spectrophotometria may be also used for the process of appreciation of one’s substance concentration, only if being guided by standards bought especially for this product.
We have nothing against mass spectrophotometry as a method of analysis but if you intend to prove that you've done a correct analysis using this method, please provide us with following documents that are missing:

  1. a blank of reactive,
  2. the probe of positive control (standards or mix of standards used),
  3. the sample that has been tested.

Regarding the “blondes and brunets” example
The Mass spectrophotometer will identify correctly 8 brunets and 2 blondes.. this is the primary identification. It is correct, but in order for one to obtain it, he should be guided by the standard which in most of the cases is a part of the equipment’s database. If there is no standard in the database, it will only show a result of 8+2, without details about whether they are blonde or brunet.
Later on, when trying to appreciate the mass of these people (blondes + brunets) we should be using a standard for each hair color in particular. ( you dont use any standard !!! all standard can be bought from USP online )

THE MASS SAYS THAT PEOPLE HAVE DIFFERENT HAIR COLOR.

The HPLC method identifies the substances being guided by a reference standard. We can separate the blondes/brunets/redhaired etc. using HPLC, not only one from another but also from each other by the lightness of the blondes or by the darkness of the brunets hair.

Both of the methods can be used for identification and dosage of substances. The problem is not the method, but the way it is interpreted.

Let us go through your statement you made in a post

"The mass spec testing is able to isolate the compound, and verify the purity. If the sample has a purity >of 50%, and a concentration of 200 mg/ ml the final product would be dosed correctly at 100mg/ml"

You are wrong ! If a substance's “purity” is 50% and we use 200 mg of such a substance, the product's concentration will be of 100 mg/ml active substance + 100 mg/ml of IMPURITIES !!!

In your analysis of Trenbolone Acetate you say that the concentration is of 50 mg/ml out of the “claimed-to-be” 100 mg/ml, and the “purity” is of 11 %. The product’s concentration in this case would be 11 mg/ml.
Where the heck did you get 50 mg/ml ??? You should be having a result of 11 mg/ml.

He will write a answer ASAP. At the moment he is convinced that I deal with a freshman that copied some text from manual without understanding nothing. You will have his reply

Until now nothing even from what you said show you are right or you have any knowledge. But is good you keep comunicating with me because is the only way to prove who is right.

I will post answers for the links you posted ( pages copied from manuals ) as soon as I get them from people who are professionals

ashop's picture

Why you don't answer to the part of my post where show you or your doctor doesn't know any analytics and mathematics ? Please comment to the part written by professor, what I have wrote is not important.

Regarding other two post he is writing now, there are miscalculations there. Remember what you said: he wrote for his class ! Do not forget this tomorrow we will have fun

Someone posted this link in a thread :

https://www.dynalabs.us/content/Test-Potency-Purity.shtml

Look you see they refer to PURITY for the raws ( API ) not for the FINAL PRODUCT. There is no term of PURITY in final product. Maybe potency is for final product.

Also you see THIS LAB IS VERY GOOD. You see they mention the metods for testing ( USP )

You proved now that I AM RIGHT !!!

Testing protocols are developed based on guidelines delineated in USP <621> Chromatography and USP <851> Spectrophotometry and Light-Scattering, and are validated according to USP <1225> Validation of Compendial Procedures and ICH Guidelines.

USP means United States Pharmacopeeia !!!

You proved my point THANK YOU !

When ANGUS will test based on those methods I will respect him and his methods !!!!

This thread is now getting good and hot!........... let it rip, i want everyone to see this argument going down so that each and every one of you can make up your own mind at the end as to WHO and WHAT is CORRECT.

Thanks for the response brother............ and YES something definitely needs sorting because I for one am getting fkn sick of all these results showing that MOST gear is fkn bullcrap!!... and i for one am seriously thinking about brewing my own gear just to satisfy myself that QUALITY RAWS can be sourced and bought and a quality product can be the end result..... i have open access to mass spectrometer use if i need it......... has it stands right now around here we ALL are at the mercy of SOMEONE!.... what i want to know is WHO?

ashop's picture

I am sending this to the doctor and I will get with a reply soon. I am very happy you come with a feedback. I will post answers to those threads directly there tommorow so I can let this thread RIP. Please do not forget you said those were written for his class.

ashop's picture

I think is very simple for you to prove that you are good. Give your doctor contact to the professor you have already email and let them chat about methods. I will post results and conversations.

Until now the conversation between your doctor and professor is here
http://www.eroids.com/pics/stealth-trenbolone-acetate-hplc-tests-everyon...

and everyone can see the professor conclusion about your doctor.

If your doctor have nothing to hide put him in contact with my professor. I wait for a week and you just hide. If you have open agenda dont hide lets put everyhing in public

Nobody with PhD do some stupid analyses like you posted lets be serious. You have a freshman student with access to a MS.

ashop's picture

Sorrry for bothering your holiday. I will wait for your answers tomorrow.

ashop's picture

I sent those informations to the professor and I will get back to you with extensive informations

I only can make some comments from my level of a layman on some things here

Full Spectrum Testing: 10 people in a room, 2 blondes, 8 brunettes = 80% brunettes

CORECT. This is MS. It makes identification only who is brunettes and who is blonde. Can not tell what is the weight of each person. We look for the weight for each person right ( concentration ) Exactly what I have told. MS is used to identify what is inside and not how much.

HPLC Column testing: 10 People in a room, 2 blondes, 8 brunettes. 2 blondes are put in a different > >room and now = 100% brunettes.

This is a childish and wrong interpretation . I will get back to you here

  1. On the other link you posted somewhere "Understanding Mass Spectrometry"
    http://www.waters.com/waters/en_US/MS---Mass-Spectrometry/nav.htm?locale...

Everyone can read there with attention: Who Uses MS? Please read carefully you will see that MS is for those who work with unknown samples for identification. I think this proves again I am right. MS is used for criminologists who doesnt care what is the purity of a cocaine but they want to know if cocaine is present so they can put a ass in jail. Also is use by scientist who make research. I don't see anywhere to say that MS is used for QUALITY TESTING IN PHARMACOLOGY . It say clearly is for : "Researchers and practitioners from various disciplines and subdisciplines within chemistry, biochemistry" Do you see anywhere pharmacology ? Do you see that anywhere mention that MS should be used for testing the quality of drugs ?

ashop's picture

Please come with arguments and explanations for everything I have writen. Dont paste here a text from wiki. We are talking about TESTING THE QUALITY OF THE DRUGS IN PHARMACEUTICAL INDUSTRY. The bible for PHARMACEUTICAL INDUSTRY is Pharmacopeeia. According to Pharmacopeeia the accepted methods for testing drugs quality are MOA based on HPLC. Here are some scans from Pharmacopeeia

MS is used for identification ( to know what is inside ) but not for how much. We use HPLC to see HOW MUCH is inside. This is why HPLC is accepted.
You can use MS same way like HPLC but then machine should run in another mode using standards.

Angus, I've been trying to learn more about mass spec reports, and have been comparing the results of the normas amps you just did to some other test e you've done in the past.
On the Spectrum graph, the one with m/z, where do you get the number values to go with the concentration on intended mass /actual mass,

I noticed that on the normas labs. there were values around 801, and again at 900s.
Would that be the oil and BA/BB.

On the chromatogram graphs,I think one graph is what the compound should be, and the other two are from the sample. Do the color codes mean something? .
It is fascinating stuff! The youtube videos I watched were based on single elements, but explained the basics for me.
