Tianeptine powder is readily available (although some nootropics vendors are cutting their sources, which is a bit worrying) however I have always had more experience with the RX pills. I cannot ever seem to find an RX vendor who stocks Tianeptine pills, brand name or otherwise.
There are a few clearnet places to buy them from but the prices are prohibitively expensive, like 1 dollar or more per pill.
If anyone could help me out, that would be great. Thank you.
edit: To make it clear, ONLY SEEKING PILLS. I am not interested in the powder and already know many sources. The pills have reliably been much more helpful to me and I don't want to measure powder all the time. No, pills filled with powder from SmartDrugsForThought or whatever do not count. I'm not the only one who hasn't had a good effect with the powder.
Are you taking this for depression? I think your best bet would be to buy this over the clearnet because it isn't widely prescribed, at least in the USA it is not.
