I’m not being rude, apologies if it came across as such, it was not my intention.
The reason I asked for the brand name, is because a vendor sending fake meds is a serious accusation, and in fairness to the vendor and as a service to the community, you need to provide basic information to back up your charge.
Now that you provided the name: Siroboon, the situation is crystal clear. And so is the reason for my question regarding the brand.
The vendor is not at fault here. YOU selected this brand “Siroboon”, the vendor just sent you the product that you selected.
It is exactly as I suspected. If you do a search of this site, you will quickly discover that Siroboon is the one brand of sirolimus/rapamycin you should never order. In multiple tests it has been shown to either not contain rapamycin, not in the right amount, or the form of it is not bioavailable. People have tested this and alerted the community to the problem with this brand.
You are indeed correct - what you received does not work. And the problem is the brand that you yourself have selected. Warnings against this brand are all over this site.
I have not gone to the GP Pharma International site, but are you sure that Siroboon is the only brand of rapamycin they offer? Sounds odd. In any case, the vendor cannot vet every medication on the market. They sell what’s on offer. They’re just a middleman. If they send you a fake product that’s a serious matter, but if it’s a product on the market that you freely selected, then they just sent you what you ordered.
You are right to ask for recommendations for reliable vendors - we all do so, myself included, and we provide feedback for the benefit of the community. However we also exchange feedback on brands, and Siroboon is widely warned against by multiple people here (myself included).
I am sorry you had this experience, and apologize if I came across as rude rather than careful and thorough (I try to be the latter!).
However it is essential to provide key information so that you may receive the proper feedback. In this case: Siroboon is the key piece of information without which nothing can be determined - it is a brand to be avoided.
There are several good vendors here. I can personally attest to the reliability of Jagdish (his contact info is in many posts in this thread). Ask for Rapacan by Eris, that is a brand most of us here order, and one I have tested with blood tests repeatedly with very good results.
Also, while going by symptoms is a good method, if you want to be absolutely sure you are getting a certain level of rapamycin, it’s best to get a blood test for sirolimus. Best of luck!
