Too clever for me but leaving a comment for the Algorithm. Good luck with the channel!

[@seanfitzpatrick8385]

Coach Greg said to sub so im here ready to work out my brain muscles 🤕🏋

[@emsg24161]

That’s what I’m talking about man haha 💪🏻😂👌🏼

He is Dr. Banner to coach Greg’s Hulk

[@philsupremo7230]

🤣

[@Ahivalaostia88]

Your brother screamed harder than last time so I subbed.

[@Emilietaly]

those Doucette brothers olala ... one helping with my fitness, the other with my chemistry exam on isotopes mercii

My doc prescribed me this video

[@cyb3rpunk190]

Just came here for the quads

[@zakaria.ammour]

teach us smarter than last time

[@raquelvictoria3417]

From coach Greg’s channel but I’m a chem major and in orgo right now. I love chemistry! Will be going to med school & training harder than last time 😜

[@slushyslushy7777]

Discovered you through greg. Going to stay for the reason that I actually understood & enjoyed this.

[@mysteryman8579]

I got a referral from my DR. Here checking in

[@JamesWilson01]

Hey, here from coach Greg. Could you do a video on why doping testers need to know specific compounds (e.g. anabolic steroids) to look for? I remember the Balco bust in the 2000s where athletes were recklessly using THG because it was unknown to authorities. Why could a tester not take some (animal?) androgen receptors in vitro and see what molecules from an athlete's blood binds to it? Wouldn't that allow detection of any novel compounds being used which could then be identified by NMR? (Forgive me if my terminology is wrong, it's been a while since I studied this stuff!)

[@ANDROID204]

Dr.Doucette sent me here, This channel is a goldmine

[@CrankedWheels]

This is Dr. Banner and Hulk all over again

[@alexmadrid8156]

Learning more than last time!

[@pantheraleo2490]

Glad I came over from Greg’s channel, my ears appreciate the change in pace

[@onerider808]

Hi, Greg sent us weight-lifting geeks here. I’m so excited to learn!

[@kevinbenoit8845]

A fan of your brother but also a chemist. This is pretty fascinating!

[@zNyteHD]

The real doctor Ducette

[@kevinsj99]

Please post more chemistry related PED videos Dr. Doucette :)

[@LilbitfitnessCA]

Hey 👋🏻 So I know that you were in the family first, but I still want to welcome you to Coach Greg’s family! I am a fitness and nutrition coach. Fitness saved my life and now I’m passionate about learning as much as I can about it, hence why I follow the doc. However, I just got into nursing school. We have to learn a lot of smart people stuff over the next few years soooo I thought it would benefit me to follow Coach Greg’s cousin as well 🤷🏼‍♀️Hope you keep posting more than last time.

[@Amaxing-r]

Here to give this channel a supraphysiological dose of algorithm

[@emsg24161]

Came here for your twin Greg, he is my doctor

[@silverback1335]

A Mass Spectrometer machine? Man I wish we had one at my gym, I'd be huge

[@onerider808]

Fascinating; thanks. I’ll eagerly watch more!

[@tcxandy]

More algorithm comments than last time.

[@83gt17]

This was actually fascinating.

[@MINI_JasperJunior]

More subscribers than last time. 🥳

[@peterlindholm8766]

Fascinating, thanks for the video.

[@TheC4RB1N3]

Awesome video🐐

[@CrankedWheels]

Now we have two Doctors

[@tinemapa78]

more brothers than last time

[@MDF4072]

Smarter than last time definitely

[@alexb5391]

Thanks a lot, very interesting topic and great presentation!

[@GR-uc1gq]

From one doctor to another.

Nice channel

[@koksalan75]

Some use elemental analyzer before doing all this, why is that?

[@ryenmaxwell6960]

Very cool

[@-_______________________.___]

Hey Chem coach! Can you teach us how to synthesize tren?

[@gustavofring4363]

Thank you sir

[@PascalC.C]

Wow thats coach greg brain on HRT

[@Adam-ir4ck]

Much smarter than last time

[@emsg24161]

More quads than last time 😋

[@philsupremo7230]

More doctors than last time!

[@astrowing4952]

In the description of the mass-spectrometer, you meant that the 12CO or 13CO molecules are first ionised before being bent by the magnetic field.

[@shortchemistry7927]

Exactly. With mass spectrometry, you are always dealing with charged ions, which are created in the ions source. There is another video that goes into more detail on how a magnetic sector mass spectrometer works, and another on electron ionization, in case you want to learn more.

SMARTER THAN LAST TIME

[@at3812]

Coach Greg is smart, but the Doc here ...is the real deal.

[@showtaker]

Greg is our dad, we have been introduced to our new uncle, hallo :)

[@francynebrooks8279]

My doctor sent me here to watch harder than last time

[@nicksearles3996]

I have been sent from your evil twin, to become smarter than last time!

[@capitantilapia]

Harder to understand for a humanities student than last time

[@LifestriderX]

I see the blood of the doc runs in the family

[@Quinicus]

Let's roll boys

[@TheLaser14]

Im sorry, im not that smart i only move heavy objects from a to b but have a good day

[@LilbitfitnessCA]

We pick stuff up, then put it down. More stuff than last time.

[@Adam-ir4ck]

🤣🤣🤣

[@nickfalzone7955]

Greg Doucette's brother is a smart man

[@stiggya4758]

I understand ZEEERRROOOO. Scream at me next time

[@alterdestiny1]

i am only as smart as the next guy. but maybe if i am here, i will be smarter than last time.

[@BuildingBetterBoxers]

Let’s see a calibration

[@johnsg94]

Is this the technique they use to estimate the age of fossils?

[@shortchemistry7927]

That's actually a different strategy. Still based on careful measurements of isotopes, but it needs even more specialized equipment called an Accelerator Mass Spectrometer. They actually take advantage of the nuclear fallout released from all the bomb testing in the middle of the 20th century to calibrate the age of samples. For older samples like fossils, they need to look at longer lived isotopes (radioactive carbon 14 decays too quickly). Thanks for your question!

[@luke67121]

how can i calculate isotope ratio on french toast?

[@holychicin8738]

you need to get u a baby Nakey and a Gert they are smarter then us Humans 💪💪🔥❤️
