What do I actually have, is this DHB CYP?

I have been working my through 50 grams of what I thought was DHB CYP aka 1-test. I am about to make another batch and decided to double check my melting temp. I have found 3-4 sources saying the melting point is around 195 Celsius. Then I have also found a site saying the melting point is 101 Celsius and finally I found a site saying the melting point is 119 Celsius. So I decided to see where my "dhb cyp" melts at and mine melted at 119 give or take.

The site saying 101 is a site in English and French so I assume it's not a Chinese manufacturer. The other site for the 195 were all manufacturers along with the site saying 119. So I can sorta throw out the 101 as
having non verifiable credentials. That leaves the 195 and the 119 which did come from a Chinese manufacturer's site so I want to believe they know what they are doing and it has to be me on my end that is miss reading or something.

What do I have that melts at 119? And fyi it has issues holding once I get up to 150mgs per ml, well that brew had issues holding but that was early in my brewing career.

I’ll bump this for those who know

What are you using to brew it with? 150mg per ml is kinda high and hard to hold in general for dhb. Plus the pip on 150mg has got to be bad. At that dose you would have to use a very high amount of gauicol. What’s your ratios looking like?

I did 20%bb 2%ba, 10%giaucol, then the QS for the carrier was MCT and mig 812 or maybe 840. I don't have the jug I front of me. I do know it's the MIG that tends to act like a solvent.

And I had no issues brewing and holding. It made it through the vacuum filter fine then I just let it sit overnight to be sure. It was fine. I still reheated and auto stirred it. It cooled down then I vialed it. It then crashed in the vials overnight. I have this trick I use and basically if it crashes in the vial then I put the vials in direct Arizona sunlight. After spending a day in the Arizona sunlight it has held just fine.


HOWEVER when I test pinned two cc I accidentally went into the cheek I had put 2ccs of other hormones the night before. I had forgot which cheek and did t realize until two days later when my ass swelled.

Now I then only pinned 1cc with another 1cc of test in the same syringe into my good cheek, no issues so far, it's been 3 days.
