My gout always flare out after 2 to 3 days from taking Siroboon brand.

How do Sirboon—Rapacan— siromus compare to each other?

I was quoted $102/100 of siromus.
$60/100 of Rapacan and $40/100 of Sirboon.

Welcome!
I’ll let someone else answer your question, but if you happen to be in the US, and if you have an rx, I wanted to let you know that through good rx, you can get 180 pills for aprox 110 at your pharmacy.

Thank you Beth,

That’s an amazing deal on Rapamycin, but I don’t have a prescription or a doctor. I’m scheduled to meet with a new doctor in June 2026. Healthcare is awful over hear and I hear it probably won’t get better.

The Zydus Siromus, and Biocon/Eris Rapacan are probably your best options. Zydus seems to be the highest quality provider and most consistent. Biocon/Eris Rapacan less so, and at the bottom is Siroboon. People have reported widely variable results with Siroboon; they are the smallest of companies on the list, and so I suspect their quality control is not nearly as good as the larger companies (Zydus is the largest, and sells globally, a multi-billion $ company).

Little update on the Siroash brand here. I’ve been using it and it seems totally fine. I don’t notice any difference compared to the other brands I have used.

I’m so surprised anyone is still considering Siroboon unless I’ve misunderstood the results I’ve seen posted on this forum of blood tests showing little or inconsistent serum concentrations.

The price is tempting, but I would definitely go with Rapacan or the Zydus product.
