Where I Started Looking
First off, I tried those regular search engines like everyone else would. Typed “where to buy josais” and got flooded with sketchy websites. Most looked like they were made overnight – broken English, prices too good to be true, zero contact info. Felt like walking through a digital flea market at midnight. Closed like 20 tabs immediately.

Asking Around Got Messy
Next, hit up forums and online groups discussing similar stuff. Bad move. Every thread had some random dude claiming “I know a guy who knows a supplier.” Messaged three of those “reliable sources.” First ghosted me after I asked basic questions. Second demanded crypto payment upfront. Third sent samples with blurry photos that looked like stale herbs. Wasted two weeks chasing smoke.
The Game-Changing Approach
Finally sat down and picked through academic papers and legit trade publications. Focused ONLY on institutions cited multiple times across different studies. Digging footnotes became my new hobby – boring but effective. Found three key sources consistently referenced by researchers:
- University agricultural departments running long-term projects on this stuff
- Licensed specialty distributors requiring official documentation before orders
- Controlled grower co-ops publishing batch test results publicly
How I Verified Them Properly
Made actual phone calls instead of emails. Asked each place point-blank:
- “Walk me through your authentication process step-by-step”
- “Show me third-party lab reports from last month”
- “What happens if samples don’t match your claims?”
Two got defensive and hung up. Real ones explained everything patiently, even mailed physical verification docs. Tested small batches from final contenders myself – took notes on texture, scent, consistency. Sounds nerdy, but cross-referenced everything with published standards in those journals.
Trustworthy Spots I’d Actually Recommend
After all that legwork, these passed my personal “no-BS” test:
- R&D hubs at public universities (they’ll redirect to approved suppliers)
- Niche certification bodies maintaining vetted provider lists
- Industry-specific exchanges where sellers get rated transparently
Found most good suppliers don’t even appear on search results. You gotta go backward – start from scientific papers and work downward to distributors. Sounds counterintuitive but saved me from wasting cash.
