QSC Wellness covers the science of metabolic health, longevity, hormone optimisation, and recovery. Research compounds from QSC (Qingdao Sigma Chemical) — 75+ peptides at ≥99% purity, shipped domestically from 8 regions worldwide.
Four pillars of peptide research — each with dedicated compound guides, protocol libraries, and sourcing information.
GLP-1 receptor agonists represent the most significant advance in metabolic research of the past decade. Semaglutide, Tirzepatide, and Retatrutide are studied for body composition, insulin sensitivity, and cardiovascular risk reduction.
Explore metabolic peptides →From telomere biology (Epitalon) to mitochondrial protection (SS-31, Humanin, MOTS-c) and senolytic research (FOXO4-DRI), QSC's longevity compound catalogue covers the most researched mechanisms of biological ageing.
Explore longevity compounds →Growth hormone secretagogues (CJC-1295, Ipamorelin, MK-677), testosterone support compounds, and peptide-based hormone axis research. Includes female-specific protocols without androgenic compounds.
Explore hormone research →BPC-157 and TB-500 for tissue repair; GHK-Cu for collagen and wound healing; Thymosin Alpha-1 for immune modulation. The recovery stack is the most practitioner-researched category in the QSC catalogue.
Explore recovery peptides →QSC's curated stacks combine synergistic compounds into single-order research packages.
The flagship men's research kit. Eight research pathways: metabolic, GH, androgenic, skin, neural, recovery, antioxidant, and sexual health.
Full protocol breakdown →Women's wellness research protocol. Six pathways: metabolic, skin and collagen, energy, recovery, longevity, and sexual health. Zero androgenic compounds.
Full protocol breakdown →The most comprehensive anti-aging research stack. Ten pathways targeting telomere biology, mitochondrial function, senolysis, immune modulation, and more.
Full protocol breakdown →GLP-1 receptor agonists have reshaped metabolic research. Here's how the major compounds compare.

Full GLP-1 Research Guide →Not all research peptide suppliers are equal. Here's what separates QSC from the market.
QSC (Qingdao Sigma Chemical) manufactures peptides via Fmoc solid-phase peptide synthesis (SPPS) at its Qingdao facility and through a vetted partner synthesis network. Not a reseller.
Every batch tested by reverse-phase HPLC and mass spectrometry. The gold standard for research compounds. Independent COA from Janoshik Analytical Laboratories — publicly verifiable.
Warehouses in USA, EU, UK, Canada, Australia, Singapore, Thailand, and Vietnam. Domestic fulfilment means faster delivery and lower customs risk for most destinations.
75+ compounds. ≥99% purity. Janoshik COA. Domestic shipping from 8 regions worldwide. BTC/USDT accepted.
