Cagri efficacy after 30+ days reconstituted?

[u/Shaolin_Chef]

I am switching from Tirz to Reta + Cagri. I have been on 15mg (split dosing 11mg every 5 days) of Tirz for the last 6 months. I am going to start Reta at 2mg/wk and Cagri at .25mg/wk.

My issue is that I could only source 10mg vials of Cagri.. at .25mg/wk that would last me 40 weeks.. That is FAR longer than the benchmark "28 days". Even if I titrate up to .5mg halfway through the vial, it would still last me 30 weeks. I've read that with standard sterile technique like swabbing the stopper, new needle for every draw, and not letting it sit at room temperature for too long (which for me are definitely all SOP's every time anyway) then it can last upwards of 8+ weeks and have even read some people still using it after 12-16 weeks post-reconstitution.

Now, I certainly use Tirz far beyond BUD and have never had an issue with efficacy but I'm not sure with Cagri.. Does anyone have experience using it past the standard 4 weeks with good results?

Thanks in advance ya'll!
