MESO-Rx Sponsor STANFORD PHARMA PUBLIC SALE 10/24/21

I disagree in the fact that their bac water may be over the .9% and that's what is causing the issues. There is a allowable variance and if their batch is 1% or more this can cause the cloudiness.
I am grateful we were able to decouple the cloudiness issue from the bubbles. I have no data to disprove your >1% BA hypothesis on the cloudiness issue and appreciate you taking the time to share your observations and data.

I found this by testing the issue a few years back. That's the only thing I may disagree with. This is why I new it was the issue before I reconstituted the vial yesterday. I don't mind the wasted product to determine this. As long as I get my flowers for discovering this. Maybe even by giving this a name like "the Stanford anomoly" or something, lol.

Here are your flowers for working so diligently to resolve these questions for members. My offer stands and appreciate you.

That being said, I Tested product and came back really good, I answered the cloudiness question and now the bubbles question. I gotta ask... what's next? The product is good.

Nothing next as far as I can tell. The idea that >=1% BA water can cause enough aggregation (or whatever is happening) to cause the cloudiness is an interesting one and just another experiment to add to the list for testing to see if Jano can pick up the cloudiness on his "dimer and related proteins" test.
I didn't plan on using product and was only answering the cloudiness question, so wasn't concerned with "slowly" adding bac water. Now the bubbles became an issue so I slowly added water. I'm doing my best to answer the questions, right?

You absolutely are and now members can be confident they should not be seeing bubbles when reconstituting properly. Thank you.

Happy to do so. I respect what you and ghoul do for the community and am happy to help if it's what's best for everyone.

Sorry if any of this comes as being forward or rude. Just typing fast and busy as heck so not putting a lot into what's being said or proof reading or anything.

Best wishes to you Stan and we can DM about the reimbursement. Thanks again for your time.

No need for reimbursement. Just being playful about the flowers. Happy to do such.

See Fig. 2

I'll see if I can find similar studies with somatropin.
 
Here we go, early work by Genentech.


10 mg/ml (~1%) loading. Would be interesting to see higher loadings of the preservatives.

As determined by various methodologies, most of the phenolic compounds caused rhGH aggregation, especially at high concentrations. Stress studies under freezing, high-temperature incubation, and agitation suggest that the destabilizing influence of the compounds tested increases in the order of benzyl alcohol < phenol × resorcinol < catechol < meta-cresol < 2-chlorophenol. Non-aromatic alcohols, except 2,6-dimethylcyclohexanol, have a much less adverse effect. Determination of the thermal transition temperature by microcalorimetry studies also reflected this trend. From our study, we conclude: (1) the phenolic additive-induced rhGH aggregates were held by non-covalent forces; (2) no significant physical binding occurred between the protein and these compounds; (3) the aggregation tendency of the phenolic compounds failed to correlate with their hydrogen bonding strength; (4) the presence of a phenolic additive caused conformational changes in rhGH's structure; (5) the effect of these phenolic compounds on rhGH aggregation decreased at high and low pHs.

Thanks for the education @Stanfordpharma1 and very helpful discussion.

Gently reconstitute your vials folks. Read the insert for Zomacton or Omnitropin. Don't shoot the water stream violently on the puck.

Nanotech injections that bestow superpowers would be much cooler. Forward not backwards. Send the price list. lol
Speaking of superpowers lifting buddy told me how the hell did my bench go up 100 pounds in two months, I said sometimes you get knocked on the head and you get superpowers it happens all the time read a comic book or something

*i take frog tech*
 
This is a customer base that appreciates a premium product. You're going to use a needle to reconstitute anyway, may as well use these. 40¢ for large gauge low pressure, pressure venting, sidewall directed flow without coring the stopper.

So when that vacuum pressure sucks the BAC it won't hit your rHGH like a fire hose.

I put the reconstitution needle in at an angle so it hits the wall of the vial and also hold the plunger back
Common sense I’d assume… I was thinking about saying this, it’s actually taking me more time to type this response sometimes I literally feel my IQ going down when I login
