80+ research-grade compounds — BPC-157, Semaglutide, Retatrutide, Ipamorelin, NAD+, MOTS-c, SARMs, PCT, PDE5 inhibitors and more. Every batch HPLC-verified at ≥99% purity with real-time Janoshik COA verification before you open the vial.
Peptides are short chains of amino acids — the molecular workhorses that regulate tissue repair, hormone signalling, metabolism, immunity, and cellular energy. Synthetic research peptides replicate or modulate these endogenous sequences, enabling researchers to probe specific biological pathways with precision.
The research peptide market has expanded dramatically, driven by breakthroughs in GLP-1 biology (Semaglutide, Tirzepatide, Retatrutide), tissue repair research (BPC-157, TB-500, GHK-Cu), mitochondrial medicine (MOTS-c, SS-31, NAD+), and longevity biology (Epitalon, FOXO4-DRI, Humanin). QSC stocks the broadest catalog of these novel compounds available from any single US-warehoused supplier.
Shop Research Compounds
All products ship from US domestic warehouse with full tracking. ≥99% HPLC purity, Janoshik-verified COA on every batch.
Purity claims are easy to make. QSC makes them verifiable. Every batch runs through a three-stage quality process before it ships:
HPLC Purity Analysis
High-Performance Liquid Chromatography separates compound from impurities. Every batch must reach ≥99% purity before release. Substandard batches are rejected.
⚗️
Mass Spectrometry
MS confirms the molecular weight matches the target compound exactly — catching synthesis errors, wrong sequences, and substitutions at the molecular level.
Janoshik COA
Every batch COA is published on verify.janoshik.com. Your COA number is on the vial. Verify your specific batch before opening — not a generic batch from a different run.
Research peptides are synthetic amino acid chains produced for laboratory and scientific research. They include tissue repair peptides like BPC-157, GH secretagogues like Ipamorelin, weight management compounds like Semaglutide and Tirzepatide, and longevity peptides like Epitalon. All QSC products are for in vitro research use only.
How do I know the peptides are real and pure?
Every QSC batch undergoes HPLC purity analysis (≥99% specification), mass spectrometry confirmation, and impurity profiling. Each batch ships with a Certificate of Analysis verifiable in real time at verify.janoshik.com — confirm your specific batch before you open the vial.
How fast does QSC ship?
US domestic orders ship from our US warehouse: 2–4 business days. International orders (UK, EU, Canada, Australia) ship from a dedicated international warehouse: 3–7 business days. All orders include full tracking.
What compounds does QSC stock?
80+ research compounds including BPC-157, TB-500, Semaglutide, Tirzepatide, Retatrutide, Ipamorelin, CJC-1295, Sermorelin, HGH, IGF-1 LR3, Epitalon, NAD+, MOTS-c, SS-31, Selank, Semax, PT-141, GHK-Cu, MK-677, LGD-4033, RAD-140, Cardarine, Clomid, Enclomiphene, Tamoxifen, Tadalafil, Sildenafil, ARA-290, and many novel compounds not yet stocked by other vendors.
What payment methods does QSC accept?
Bitcoin (BTC) and USDT (ERC-20) for all orders.
How does QSC compare to Peptide Sciences or Core Peptides?
QSC differentiates through the deepest catalog of novel compounds (Retatrutide, ARA-290, Humanin, Pinealon, Survodutide, etc.), real-time Janoshik COA verification, a dedicated 100+ compound research manual, and dedicated US + international warehouses. Most competitors lack several of these.
Are peptides legal to buy?
