I am.
I purchased from ASC and SRY. Also purchased domestic via Nexaph.
You'll need some money in crypto or use Alibaba pay which I have not used. Nexaph is domestic and has some controversy. Relating to issues that might be of concern for you are one failed one sterility test but passed others. Controversy seems not to be related to product quality but other business practices. But they do ship domestic and take credit cards. And their prices are mildly competitive with overseas vendors.
I also purchased from Skye Peptides early on.... about 10x the cost of the ones I mentioned above.
