Testing question
-
Hey everyone, Source Research here. We've been reading along for a while and figured it's time to say hi.
We're a small research-use-only supplier, and testing is the part we care about most. We only work with suppliers who test extensively on their end. When a lot comes in, we keep the supplier's lot number on it and send it to an independent third-party lab for our own testing, so you can trace any vial from the supplier's batch to our COA. Every lot gets HPLC for identity and purity and its own certificate of analysis. We also publish the lots that fail. We recently rejected a GHK-Cu batch that came back over the limit for heavy metals, and it's posted right next to the ones that passed: https://sourceresearch.io/testing/
Honestly, we think this should be the industry standard: supplier testing plus independent retesting, tied to one traceable lot number. It feels like what the market's asking for. But we'd rather hear it from you than assume. Is that level of traceability something you look for? Which tests matter most to you when you're deciding whether to trust a lot?
Glad to be here, and thanks for having us. -
I like the website and the push for transparency. Just a quick question on your BPC-157 10 mg
There are 2 COA's listed.
For Lot xzgt3gk- Peptide is pure (99.78%), but each vial only contains 8.26 mg of active BPC-157. Also no verified safety data for heavy metals or sterility.For Lot sr-bpc-260316-001- Peptide meets the dosage claim (10.34 mg), purity and passed all checks for sterility/endotoxins
So which lot are you actively shipping?

Thanks so much, and great question. That's exactly the kind of checking we hope people will do.
The lot we're shipping right now is sr-bpc-260316-001, which our independent lab tested at 10.34 mg.
xzgt3gk is our supplier's lot number, and the 8.26 mg result is from their COA, not ours. We share the source COA for the compounds we're selling now because we want to be transparent, and we know there's a gap between their numbers and ours. That's something we're fixing.
Going forward, every lot will be tied to the lot our supplier sells us and tests. If our COA and theirs don't match, we won't sell it that lot, and our supplier has committed to the same. Our supplier is ClearBatch, and we're proud to work with them.
If you'd like, DM me and I'll send you some free BPC-157 for your own testing, as thanks for such a thoughtful question. Questions like this make us better.
