International Research Peptide Supplier
Research Peptide Science, Made Accessible, Shipped From Your Local Warehouse
QSC vision is to make research peptides more accessible. As a direct manufacturer and through trusted manufacturing partners, every compound is verified at ≥99% purity and ships domestically from USA, EU, UK, Canada, or Australia.
QSC’s Clavicular Stack is a 12-compound, 110-vials and 100 tablets extended research kit targeting 8 biological pathways simultaneously — triple-agonist metabolic signaling, GH axis + secretagogue amplification, melanocortin pigmentation, IGF-mediated anabolism, copper-peptide collagen remodeling, mitochondrial bioenergetics, antioxidant cytoprotection, tissue repair/healing, and androgenic/anabolic drive. Expanded from the original 7-compound stack with L-Glutathione, BPC-157, TB-500, CJC-1295 No DAC, and Anavar for complete protocol coverage. The Clavicular Ascension Stack consists of 12 compounds: 10 lyophilized peptides (10‑vial/pack kits), 1 oil‑based injectable (10‑vial/pack kit), and 1 bottle of 100 oral tablets under QSC’s strict ≥99% purity standard with full Janoshik COA documentation.
Modified IGF-1 with 20–30 hour half-life. Activates PI3K/Akt and MAPK/ERK for muscle hyperplasia, tissue repair, and nutrient partitioning. Lyophilized powder.
Nicotinamide Adenine Dinucleotide — Cellular Energy
Mitochondrial electron carrier and sirtuin substrate (SIRT1–7). Researched for DNA repair, anti-aging, cognitive resilience, and energy restoration. Lyophilized powder, 500mg/vial.
15-AA gastric pentadecapeptide modulating NO pathways and growth factor signaling. Researched for tendon/ligament/muscle repair, gut healing, and neuroprotection. Lyophilized powder.
Actin-binding peptide for cell migration, angiogenesis, and inflammation reduction. Synergistic with BPC-157 in recovery protocols. Lyophilized powder.
When inventory is available locally, your order ships domestically — no customs clearance, local courier tracking, and typical delivery in 2–7 business days.
QSC is one of the most recognised peptide suppliers in the global research community, making high-purity research peptides more accessible to laboratories, distributors, and the growing looksmaxxing research community in more than 100 countries.
QSC operates as both a direct manufacturer and through a vetted partnership model. Core peptides are produced in-house using solid-phase peptide synthesis (SPPS), advanced purification systems, and full analytical testing. QSC also partners with rigorously vetted manufacturers to expand its catalog — ensuring every product, whether in-house or partner-sourced, undergoes the same quality control process including HPLC purity analysis, mass spectrometry, and impurity profiling.
The qsc-eu.com storefront is the dedicated US and international distribution interface for QSC products, operated to serve researchers in North America, Europe, Oceania, Asia, and beyond.
QSC maintains domestic warehouses in the United States, European Union, United Kingdom, Canada, and Australia. When your product is in stock locally, it ships domestically with no customs clearance required. International shipping via the China warehouse is available for international.
What purity are QSC peptides?
QSC research peptides are verified at ≥99% purity by HPLC analysis and mass spectrometry. Every product page includes a Certificate of Analysis (COA) independently verifiable via the Janoshik testing portal — not just available on request, but proactively published for every batch.
Is QSC the manufacturer or a reseller?
QSC operates as both a direct manufacturer and through a partnership model. Core peptides are produced in-house using solid-phase peptide synthesis (SPPS), purified by preparative HPLC, lyophilized, and analytically verified. QSC also partners with rigorously vetted manufacturers to expand its product range — all partner-sourced products undergo the same QSC quality control process before distribution. QSC does not source product from undisclosed or unvetted third parties.
What payment methods does QSC accept?
QSC accepts Bitcoin (BTC) and USDT (ERC-20) cryptocurrency payments for all orders worldwide. After checkout you will receive payment instructions and a confirmation email with tracking information once your order ships.
