Shanghai Sigma-Audley New Material Technology Co., Ltd.

6 lots logged now, purity 99.1 to 99.2%. A band that tight is worth more to me than one spectacular number.

Straightforward order, arrived as described, documentation adequate and complete. Nothing to add, which is the point.

Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.

Every certificate I have from them is lot-specific. Not one batch-level document in 6 orders.

First order, deliberately small, glutathione 600 mg only. Documentation, transit and a Janoshik result at 98.2% all checked out, so the next one will not be small.

Janoshik has now seen 4 of their lots through me. Not one has come back outside spec.

Fifth order from them, all BPC-157 5 mg. Sent one vial from each to VendorInvestigate and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.

Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.

Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.

Submitted the semax 10 mg to Janoshik blind, without telling them the source. 99.5% against a stated 99.4%. The number holds up when nobody knows whose vial it is.

Fair pricing for the documentation standard, and delivery landed on day 4 as quoted.

Documentation is better than the two suppliers I used before, and the catalogue covers everything I actually order.

Pleased to find they hold stock in Germany. Domestic dispatch, day 4, no customs step at all.

Cold pack was still hard on arrival in Minneapolis on day 5. My logger never went above 4°C across the whole run.

Consistent rather than flashy. Everything lands in the high nineties, and it lands there every time.

Asked them to hold an order until I confirmed a lot number and they did, without fuss and without a restocking charge.

Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.

Reordered on the strength of the last one and got an identical result. Repeatability is the product.

Weighed 6 vials from the BPC-157 10 mg order against label. Every one inside 2% of stated mass. Fill consistency is harder than purity and they have it.

Certificate claimed 97.7% on lot SSA-25-377. VendorInvestigate came back 97.9%. On an independent column that is as close to agreement as this gets.

Domestic dispatch from their stock in Canada. Straightforward, day 3, exactly as quoted.

Reliable on the general catalogue lines. Purity figures cluster tightly and the certificates match the lots.

Peptide content reported at 98.1% alongside the purity figure, so I could convert straight to a working mass.

Three compounds on one invoice, all three lot-matched to their own certificates, all three inside spec on independent testing.

Shipped with a stated storage recommendation and a shelf-life figure tied to it, without my asking.

Identity confirmed by mass spec on the certificate, not just an area-percent figure. Both questions answered on one page.
