Since we now have more than a few folks experimenting with Rapamycin, I thought it might be useful to have a central location to discuss and share places to purchase, vendors etc... 

Points that may be helpful, but not limited to:

Name of vendor
Link to Website
Dosages available (mg per pill)
Cost (per mg)
Shipping costs
Shipping efficiency
Overall experience

Dropshipmd.com
India - sirolimus 1 mg
ordered 300 at 1.75 mg
small orders are much more expensive
also ordered Metformin SR 1000 mg 550 ea for 100 dollars. Bank wires only no paypal or cc. Free slow shipping. About 4 weeks. They probably also have other drugs in anti ageing formula. Statins, ang II INHIBITORS ETC

I agree Dropshipmd provides a fast and excellent source for Rapamycin.

 I bought some TLR rapamycin which came in a very small packet (500 mg). Another poster said the way he took it was to dilute it with alcohol and use an eyedropper to to dose it out. I can say for a fact this did not work for me. My first shipment came from India (the real deal). When that ran out  I thought I would try TLR to save money. With TLR my weight started to rise and I regained half the weight I lost with the real rapamycin within a month. I tried doing doses that I knew in the past would give me mouth ulcers and after repeated tries nothing.That is a big tell. I will get mouth ulcers if I overdose.  One of three things is happening IMO:

   1. The alcohol destroys the activity of rapamycin

   2. It's fake

   3. It's real but very diluted and not really a bargain. 

I have a feeling a lot of the rapamycin that is being sold in bulk powder is fake. That's my opinion anyway.

I obtained some sirolimus (AKA rapamycin) from dropshipmd.com and also another online vendor. In both cases, I was told that it was manufactured by Biocon. However, upon receiving the product (sold as "Emcure"), I noticed that the "manufactured by" company printed on the back was Swiss Garnier Biotech in Mehatpur, India. Sounds like a dodgy company trying to sound top tier. So lucky for you, I coughed up some hard earned cash and ran a mass spec on 4 pills. Each pill weighs 177 mg and claims to contain 1 mg of sirolimus. (177 mg was measured as the average of 5 other pills after the fact. Error seems to be +/-5 mg.)

 

The mass spec was done by a professor at an American university. He had done another analysis for me previously, and had been able to clearly identify an ingredient at the right molecular weight, even though I had only provided him a search range spanning 100 g/mol.

 

In this case, we have a substance with a molecular weight of 914 g/mol, as you can see here at Wikipedia. Indeed, the results show a peak there. Furthermore, it seems confirmed by other peaks at 913 and even 912. (I assume this is a smearing out of the proper peak due to measurement error.) Note that sirolimus has an odd number of nitrogens, namely just one, which supposedly has some significance with respect to the + or - ion mode.

 

The question is: are the mass spec results posted below consistent with a pill weighing 177 mg that claims to contain 1 mg of sirolimus? The answer is complicated by the fact that the X axis has units of mass/charge, where mass is normalized to g/mol and charge is in unit electron charges (ionization state count). So a +1 ion would show 914, but a +2 ion would show 457. More to the point, the pill is expected to be over 99% filler, which creates all the noise.

I don't know how to interpret those, but typically what I do is GC/MS which requires that the sample be dissolved in a pure solvent such as analysis-grade hexane. You also need to know the ratio to % of pill vs solvent volume so you can calculate the concentration eventually. For example, if you dissolve the pill in 10ml of hexane, then the final concentration of sirolimus should be 0.1mg/ml (assuming that sirolimus does dissolve in hexane, which you'd need to check first.

 

Then, you do a Gas Chromatograph to separate the peak we're looking for, and do Mass Spec on that (or on all the peaks). Finally, you really want a mass spec database which will show you a % likelihood match for compounds, and you want that database to include sirolimus.

 

In the absence of a database, the easiest way to check would be to get a known-good sample from a chemical supply house and see if you can match the pattern against that. But you still would probably need to do GC to separate out the other material which will create confusing peaks.

Thanks, that makes sense. Unfortunately I'm not in a position to do all that. If anyone else is, I'd be happy to provide samples. I guess this basically means that the results I posted are at least consistent with a real pill. I could always buy a known-good brand and compare, but even then, the filler is probably quite different. The other thing I could do is get a higher-dose pill from the same manufacturer, but unfortunately I haven't found one from any of the vendors I've looked at.

Anecdotally, I have the same sirolimus tablets from the same manufacturer as you, and taking 5mg instantly gave me a mouth sore, which would be consistent with it being sirolimus. Not conclusive by any means, but still something.

 

I do have access to GC/MS, but it turns out that it's not very soluble in hexane, so I would have to get some reagent grade methanol before sending out a sample. Also would need to check to see if the lab I use has the compound in its MS database. So I may do that at some point, but probably not for a while.

Yeah, I recall having read that somewhere. But how is an instant mouthsore consistent with sirolimus? My impression was that the mouthsores are a gradual result of sustained immune suppression -- perhaps even bacterial colonies taking advantage of the situation, as with pimples. But perhaps I'm mistaken.

 

I did notice, for that matter, that these particular pills don't seem to be enteric coated, so presumably if you take one whole, it will just settle somewhere in your gut and cause the same local reaction. Not good. At least, I'd try to dissolve it first. How do you take it?

 

Thanks for looking into all that. I'd be really interested in further chemical analysis.

I was exaggerating about "instant". It gave me a mouth sore in a day or 2 which didn't go away for over a week.

 

I just take them as pills. I don't think there's likely to be a local reaction, but not entirely certain. Stopped for a while, but now am back to 2mg every 10 days and may try to go to 3 again if it doesn't cause a sore.

I do a lot of mass spectrometry at a major research university.  A mass spectrometer cannot confirm purity so your question is moot.   This is due to the fact that a mass spectrometer is a selective detector...it has different ionization efficiencies for different compounds which basically means some compounds give a strong signal while others give a weak signal.    The best way to measure purity is to do HPLC with a UV detector set to a nonspecific wavelength like 220nm...this wavelength will measure all compounds equally.

So we have one negative review for TeamTLR rapamycin. 

 

Has anybody else tried the TLR rapamycin and can you give us your opinion?
