Purity & COA Transparency
QSC specifies ≥99% purity for 5-Amino-1MQ, verified by HPLC and mass spectrometry. Every product page includes a Certificate of Analysis independently verifiable via the Janoshik testing portal. Small molecule NNMT inhibitor — not a peptide. Lower vendor availability globally; QSC offers with same ≥99% HPLC verification standard applied to its peptide catalog.
Core Peptides specifies ≥99% purity, tested by HPLC + MS. COA availability: Yes — third-party, on product page.
Domestic Shipping Coverage
QSC maintains domestic warehouses in USA, EU, UK, Canada, and Australia. Orders ship from the nearest warehouse — no customs, no international transit delays, typical delivery 2–7 days domestic.
Core Peptides ships domestically from: USA only. US-only domestic shipping.

Manufacturer vs Reseller
QSC is the direct SPPS manufacturer of every peptide it sells. 5-Amino-1MQ is produced in-house — synthesised, purified by preparative HPLC, lyophilised, and verified by mass spectrometry before distribution. Every batch is traceable to QSC’s own production records.
Core Peptides sources product from Third-party manufacturer. Manufacturing transparency and batch traceability differ accordingly.
Why researchers choose QSC over Core Peptides for 5-Amino-1MQ
Core Peptides is a strong competitor on purity and COA transparency — QSC matches on both. QSC’s primary advantages are domestic shipping to EU, UK, AU, and CA — regions Core Peptides cannot serve domestically — and direct manufacturer status enabling bulk pricing and custom synthesis.
Frequently Asked Questions
Is QSC or Core Peptides better for 5-Amino-1MQ?
The best choice depends on your location and requirements. Researchers in EU, UK, Australia, or Canada benefit significantly from QSC’s domestic warehouses in those regions — eliminating customs risk and reducing transit time vs vendors with US-only warehouses. For purity-sensitive quantitative research, QSC’s ≥99% specification with Janoshik-independent COA verification provides a higher and independently confirmable quality standard.
Does Core Peptides ship 5-Amino-1MQ to non-US researchers?
Core Peptides ships domestically from USA only. Researchers outside these regions receive international shipments, which may be subject to customs clearance, import duties, and extended transit. QSC maintains domestic 5-Amino-1MQ inventory in 5 regions to avoid these issues.
How does Core Peptides verify 5-Amino-1MQ purity?
Core Peptides uses HPLC + MS with Yes — third-party, on product page. QSC uses HPLC and mass spectrometry on every batch, with COAs proactively published on each product page and independently verifiable via the Janoshik portal.
Can I get custom synthesis or bulk pricing on 5-Amino-1MQ from QSC?
Yes. As the direct manufacturer, QSC can accommodate bulk orders and custom synthesis requests for 5-Amino-1MQ. Contact [email protected] with your research requirements.
