I do not recommend buying rapamycin powder from this Chinese seller
I do not recommend this seller from China:
Zhejiang Multinpharma Co., Ltd
Mobile: 0086-159-5817-3572 (WhatsApp) / +86 159 5817 3572
I purchased 10g for $200. I did the sirolimus dosage test 1 hour after taking 6mg with grapefruit seed oil, and it came back negative. When I mentioned the result to the seller, he recommended I buy higher quality rapamycin for $650.
Laur, I believe this has been reported before. Read through this link about Chris Los' story: https://forum.age-reversal.net/t/63jmdc/rapamycin-cost
Fortunately, you did not decide to purchase from them again. Careful research in this area is very important before deciding to make a purchase from China.
