Fentanyl HCL vs Fentanyl Freebase

I have been purchasing fentanyl HCL for a long time on dark web. Recently I've been seeing vendors (just a couple) advertise Fentanyl Freebase. They advertise it as if it's different from Fent HCL, but it is still Fentanyl, and at least very similar to HCL. I have tried doing research online and cannot find any information about it. I know about all of the other fent analogues, but I'm not sure what fentanyl freebase really is.

I am just wondering what the strength difference is between fentanyl HCL (let's say about 85-90% pure) vs "fentanyl freebase" that is fairly pure.

Here's an old quote I found from SunWu (old OG vendor)'s silkroad profile

"Our fentanyl citrate is exceeding 99% purity. This is the citrate salt form, not to be confused with the freebase form. The molecular weight of the free base is 336.5, as oppose to the citrate salt which has a molecular weight of 528.6 due to the addition of the citrate molecule. This means that 1g of fentanyl freebase is equivalent to 1.57g of fentanyl citrate in terms of potency. The citrate form is more stable, less prone do degradation, has a higher solubility, and is generally easier to work with than the freebase. This is not to be confused with fentanyl HCL (hydrochloride), which is made with hydrochloric acid, as oppose to citric acid. The citrate molecule is larger than the chloride molecule, Fentanyl HCL having a molecular weight of 372.9, verses Fentanyl Citrate, which has a molecular weight of 528.6. Thus 1g of Fentanyl HCL is equivalent to aproximately 1.42g of fentanyl citrate in terms of potency. Please take this into account when working with our products."

Basically from what I understand, the lower the molecular weight of a particular fentanyl salt, the more potent it is per milligram.

So I believe the freebase is more potent then HCL by about 10-11%, HCL lots more then citrate. You can work out the percentages by calculating the difference between the molecular weights.

You should also be able to transform the freebase into other salts like the HCL salt or citrate salt if you choose. However the only listings ive seen for freebase were really expensive and not worth it.

To my understanding, most freebase are smoke-able because they are the salt version, which I assume can still be active when handled at high vaporization points. I could be completely wrong tho..

Heres a question... Which one is better for shooting up?(IV'ing) You know like which one will dissolve in water? Fentanyl HCL or Fentanyl Freebase???
