ARA-290 with PBS

[MyB]

I first tried ARA from EZP and had zero issues with it. Bought a kit from Nexaph a few months ago and two of the three bottles later gelled and clumped a few days later when Hospira Bac Water was used.
Has anyone tried using PBS with success?

This article mentions using PBS for recon https://pmc.ncbi.nlm.nih.gov/articles/PMC4818260/#:~:text=The nonhematopoietic erythropoietin analogue ARA290,for up to 4 wks.

Yes, I use 1 ml pbs, let it dissolve then add .5ml to 1 ml of hospira, no gelling issues, that’s for 16mg vial

My wife’s rat is researching ARA right now. I was barely able to dissolve 3 vials into one pen cartridge with 3ml Hospira. It looked like it was going to gel but hasn’t so far.

@gym.rat nerve pain and inflammation, documentation says vascular as well. It works better than KPV in my research experience.

I used it to research neuropathy in legs and feet. It unexpectedly addressed Tarsal Tunnel Syndrome in my Rat also.

If you need to add aa or PBS to ara its a bad batch and you should not research with it.

Unfortunately ive been seeing more and more issues with resellers saying you need AA for compounds that never need it. Bathtub labs i think.

@myb red cap ara? or are they onto a new batch?

[MyB]

@randy yeah it’s the red cap batch from 2025. Was it a bad batch? Should I consider the remaining 7 a loss and source new?

[WisGal64]

I tried bac only on Friday, so far no gelling, but it usually happens on the last couple of doses for me. Keeping my fingers crossed

[Randy]

@MyB Ive gone through 5 kits of it with no issue. Was your hospira from a questionable source?

[Randy]

@MyB update. I tried reconning with .5ml today. GEL CITY.

tried 1.2 on a new bottle. Flakes that wont dissolve.

2.2ml (which is what ive always done with this batch) no issues.

[MyB]

@randy all my gelling issues come with recon 1ml BW for a 10mg vial.
Last weekend I recon bottle “A” with 1.5ml and it went cloudy, out of fear of gelling I flooded with 3ml and it went clear. Used vial “A” to recon vial “B” and got flakes. After 24hrs things did dissolve. Transferred to pen vial and been researching this week with it. No issues and still clear.
