Oxycodone from Mexico: How to tell if fake?

[Psynaught]

Greetings,

I have access to American oxy. I have had this access for a while, I always have it on hand, and it seems I am very good about only taking it about once every 5 to 7 days. I really enjoy it. I know, I know I am living dangerously but only taking this drug occasionally is pleasurable.

I just had someone come back from a trip to Mexico and out of the blue he asked me if I wanted any Mexican Oy, and the price was incredibly low.

I did some research and it seems that anywhere from 15 to 40% of the Mexican Oxy is really fentanyl. So my question is, how do I recognize real Mexican Oxy from fake? I know that a test strip from Dancesafe will test, but I need to purchase one.

I understand that the answer to this question may be no answer at all. Having said that, the pills are blue, scored in the middle, have 30 on one side and M inside a square on the other.

Thanks.

The blue M30 pills are the most faked form of oxycodone, and when bought from a Mexican pharmacy, are almost always fentanyl.

But I'm not sure what you're asking exactly, since the title of this thread is, "Oxycodone from Mexico: How to tell if fake" yet in your post you answered your own question: a fentanyl test strip can be used to detect the presence of fentanyl.

But you don't have to buy the test strips from Dancesafe; you can actually order fentanyl test strips on Amazon and have them on your doorstep tomorrow morning.

There is no other way to tell, other than sending them into a lab

Side note, though it wouldn't be a conclusive test, we should get someone on here who has an actual prescription for the 30mg M30 tablets to a pill on a milligram scale (or perhaps weigh a few and take the average). True pharmaceutical tablets often have a specific total mass, and due to the precision of manufacturer, often only differ by 1, 2 or 3 milligrams. So if we knew what a real M30 tablet weighed, and your pill in question weighted 60 milligrams more, then you would know immediately that it is fake. Of course, this is not definitive but could help rule out certain cases.

But when it comes to M30 pills not bought from a US pharmacy, one should treat as if it is fentanyl, and then test with a fentanyl strip. If negative, test with other reagents that react to indicate oxycodone or send into a lab.

Thanks, great post. I weighed 10 tabs (they are Mexican blues) and they all weigh pretty much the same. .113 grams (113 milligrams).

I purchased a test kit off Amazon.

Thanks, great post. I weighed 10 tabs (they are Mexican blues) and they all weigh pretty much the same. .113 grams (113 milligrams).

If they all consistently weigh around 113mg then they are unlikely to be oxycodone.

True, fully intact (ie, not worn down or chipped) pharmaceutical Mallinckrodt M30 oxycodone tablets weigh 130mg, and likely only deviate 1mg or so (straight out of the factory). Loss of weight does occur from friction over time, but a fully intact, right out of the bottle Mallinckrodt M30 oxycodone should weight 130mg, and should measure 6.5mm x 4mm. Below is an example of real M30 that was sent in for analysis, and you can see it weighed 129mg (the missing milligram is from slight wear):

Now compare that to this fake M30, which is a fairly high quality looking press, but notice that it weighs 112mg, and the measurements are slightly off (6.5mm x 3mm).

Alternatively some fakes weigh more than real 130mg M30s; this one weighs 157mg, which means it's impossible for it to be authentic since it's nearly 30mg overweight:

https://drugsdata.org/view.php?id=9146

That said, a fake could exist that has the same size and weight of a real M30, so testing is always essential, even if its is exactly the same size and weight.

But these known physical properties of the real M30s are most immediately helpfully in quickly revealing probable fakes. If the size and weight are notably different from the standard of 130mg and 6.5mm x 4mm, its almost certainly fake. Ones that are overweight (like 157mg) can be immediately identified as fake, since it's impossible for them to be heavier and legit (unless they are very damp or have been exposed to alot of moisture).

As far those that weight less than 130mg, its possilble that old, chipped and worn down pills that are authentic M30s can certainly lose 5-10mg over time, or even more if the pill is significantly chipped or broken, but if the pill is intact and looks fresh/not worn down, and weighs notably less than 125-130mg, and is not 6.5mm x 4mm in size, you can be pretty sure that you have a fake.

So if your 113mg M30 pills you have look freshly pressed, and are not significantly worn down or chipped, then they are almost certainly fake (especially if they all are consistently all around 113mg -- which is a big red flag since they couldnt all be worn down uniformally by 17mg). Pills that weigh 130mg don't lose 17mg of weight without appearing very significantly worn or chipped, and the fact all your pills are consistently low weight to similar degree point to them being fakes. So even if they test negative for fentanyl, they likely aren't real and instead contain something other than fentanyl.

If you want to test it further you can buy some reagents. I think marquis reagent is a common reagents to test for oxycodone/hydrocodone. I wouldn't recommend buying reagents from Dancesafe though, since they package their reagents in plastic bottles (which tend to leak). Glass bottles are better, i usually use Wim Lab's since they use glass bottle (prices are similar).

Damn @negrogesic I come in here to close a thread and unsurprisingly find you have come up with an awesome answer. I never would have considered the weights as a method of verification. Very smart as usual.

We typically close drug ID threads as they are objectively impossible to answer. In this world, it's sometimes helpful just to get "more" information. As we deal with very dangerous situations, we usually tell people it is unethical/irresponsible to put ideas in their head we are unsure of. Even with these things being known for certain, drug use is still an inherently chaotic practice.

A rule of thumb: if they are from Mexico, assume they are Fentanyl. If you buy pills in America, assume they are Fentanyl if you don't know the person very well. There is a fuckton of money in this practice. They have every reason to give you Fentanyl and essentially no incentive whatsoever to go out of their way to get you a real product.

Look at generic drugs in the United States. Even here we are worried about generics being of low quality; shit like that.

Assume your pills are Fentanyl. There is little reason for me to expect they would be anything else.

What is helpful is that we know Fentanyl et al is the primary Opioid used. This means we have a readily available means of determining one way or the other .

If it doesn't test positive for Fentanyl, it could be a different Opioid. For instance, Nitazenes are a large minority of the supply. They are similarly very powerful Opioids.

We are not supposed to help people source. However, my heart aches for folks with no other recourse but Fentanyl.

It's fairly common knowledge that the Dark Web exists and that anything illegal can be obtained there. You will pay a premium, but you can actually get real drugs.

Without a doubt, it would be better to hi that route. Maybe you won't be able to use as much dope. We all know though that using less feels better than using more, so it's a win win.

Yes, the press and finish on these were high quality. However I tested them and sure enough they tested positive for fentanyl. I tried one the other day and felt good, waited an hour tried another, then another hour.

They definitely reduced pain but did not provide the euphoria of real Oxy. Also, the price was so cheap (I believe I cannot talk about price) that they probably could not be real Oxys.

I took 1 last night however and it was great for pain relief. I will keep them around for that purpose as I do have quite a bit of physical pain that I live with. I also ordered some Narcan to be safe.

I think that as long as I only take 1 at a time and limit that to twice a week I will be OK. Eventually I will most likely see a pain specialist, although I have my doubts that he/she will actually help me.
