QSC ships domestically to 5 regions vs Peptide Sciences’ US-only warehouse. QSC is the direct SPPS manufacturer with Janoshik-verifiable COAs on every product page. For researchers outside the USA, QSC’s domestic United States, Australia warehouses eliminate customs risk entirely.
Frequently Asked Questions
Is QSC or Peptide Sciences better for CJC-1295 (No DAC)?
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 Peptide Sciences ship CJC-1295 (No DAC) to non-US researchers?
Peptide Sciences 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 CJC-1295 (No DAC) inventory in 5 regions to avoid these issues.
How does Peptide Sciences verify CJC-1295 (No DAC) purity?
Peptide Sciences uses HPLC with Yes — third-party tested. QSC uses HPLC and mass spectrometry on every batch, with COAs proactively published on each product page and independently verifiable via the Janoshik portal.
