Purity & COA Transparency
QSC specifies ≥99% purity for HGH, verified by HPLC and mass spectrometry. Every product page includes a Certificate of Analysis independently verifiable via the Janoshik testing portal. Recombinant HGH (somatropin) — 191-amino acid protein, not a conventional SPPS peptide. QSC’s direct manufacturing and 5-region domestic warehouses are particularly relevant for HGH given temperature-sensitive shipping requirements.
Amino Asylum specifies ≥98% purity, tested by HPLC. COA availability: Yes — third-party.
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.
Amino Asylum ships domestically from: USA only. ≥98% purity specification.

Manufacturer vs Reseller
QSC is the direct SPPS manufacturer of every peptide it sells. HGH 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.
Amino Asylum sources product from Third-party manufacturer. Manufacturing transparency and batch traceability differ accordingly.
Why researchers choose QSC over Amino Asylum for HGH
QSC’s ≥99% purity with Janoshik-verifiable COAs is a measurable analytical advantage over Amino Asylum’s ≥98% specification. QSC’s direct manufacturer status means consistent batch availability. QSC offers domestic United States, United Kingdom, Australia shipping — non-US Amino Asylum customers pay international rates and face customs risk.
Frequently Asked Questions
Is QSC or Amino Asylum better for HGH?
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 Amino Asylum ship HGH to non-US researchers?
Amino Asylum 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 HGH inventory in 5 regions to avoid these issues.
How does Amino Asylum verify HGH purity?
Amino Asylum uses HPLC with Yes — third-party. 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 HGH from QSC?
Yes. As the direct manufacturer, QSC can accommodate bulk orders and custom synthesis requests for HGH. Contact [email protected] with your research requirements.
