Damaging the hormone?

[safarifilms]

Hey all

This may be a dumb question but I’m gonna ask anyway.

When brewing any raw to injectable does one damage the hormone if you brew the total contents past the hormones melting point?

Example if test E melt point is 30C and I brew it at 60C will it be damaged?

Does each compound need to be brewed at its melting point temp? Just want to make sure I’m doing it right.

Thanks guys

No, when brewing the heat is used to help dissolving the raw into the carrier.

You don't have to brew at melting point,
some compounds have pretty high melting point, for example DHB is like 159C, but you don't have to heat it to that temperature.

Other compounds have low melting point, Equipoise, for example is liquid at room temperature, does it mean that it damages? No.
Same thing for Test E, brewing it past 30C up to 60C won't damage it.

The standard rule is that 50C or 60C should be enough to dissolve any compound, and won't damage it,
going past that temperature doesn't have any benefit, and may possibly damage the compound.

Thank you so much for clarifying that for me. Merry Christmas

I know this has nothing to do with the topic, but does anyone here sterilize their vials in an autoclave with the oil already inside? I mean, I have the vials already sterilized and dried, once they are filled and filtered I normally seal them and that's it, but recently I've seen that there are people who sterilize everything together to finish the process, sounds good, but wouldn't this poison the benzyl benzoate and benzyl alcohol? I mean it's 138º Celsius, wouldn't that also degrade the hormone?

It's fine.

This is an FDA compliant compounding pharmacy recipe for Test-cyp.


Look at the final sterilization in step 5.

This is the correct answer.

Structural Insights and Intermolecular Energy for Some Medium and Long-Chain Testosterone Esters - PMC

Testosterone (17β-Hydroxyandrost-4-en-3-one) is the primary male anabolic-androgenic steroid. The crystal structures of two medium and two long esterified forms of testosterone, including enanthate, cypionate, decanoate and undecanoate, were ...

DTA/TG curves of analyzed compounds are shown in Figure S5 (Supporting Information). Small endothermic peaks appear at (42 °C for Tena), (97 °C for TCyp), (49 °C for TDec) and (65 °C for TUnd), and are assigned to the melting points of the compounds. It should be mentioned that TEna has the lowest melting point, and in the solubility evolution process it became gelatinous even though it was assessed at 14 °C.

With the increase in temperature, no thermal events occurred until the onset temperature of 320 °C for long esters (TDec, TUnd) and up to 350 °C for medium esters (TEna, TCyp).

Further, two broad exothermic peaks were recorded. The first peak had its maximum at the following temperatures: (381 °C, TEna), (393 °C, TCyp), (378 °C, TDec) and (387 °C, TUnd). This peak can be attributed to the process of degradation and oxidation of organic matter, accompanied by a significant loss of mass. The second exothermic peak, with maxima (544 °C, TEna), (537 °C, TCyp), (540 °C, TDec), (540 °C, TUnd), can be associated with the decomposition and oxidation of the remaining material simultaneously with a less significant loss of mass. Similar thermal behavior has been reported for other active pharmaceutical ingredients such as riboflavin and norfloxacin

This study has also been used here for reference purposes regarding testosterone solubility for different esters in different carrier oils. Unfortunately, a slight mathematical modification of the solubility results must be made to show the information using the same context we do about mg/ml in our normal discussions. If the results are not recalculated, we will mistakenly believe testosterone mg/ml limits are significantly higher than what we are used to, which is not the case.

I am curious if anyone else has found our misinterpretation "mistake."
