Compounds Discussed on Meso-Rx β Sourced at QSC US domestic Β· Janoshik independent COA Β· 80+ compounds Β· 2β4 day delivery
QSC stocks research-grade versions of the steroids, SARMs, peptides, and GLP-1 compounds most discussed in Meso-Rx forums β all at β₯99% HPLC purity with Janoshik independently verified COA, publicly checkable at verify.janoshik.com.
Meso-Rx is the benchmark community for serious research on anabolic compounds, peptides, and performance biology. QSC is built for exactly this research community β a US domestic supplier with independently verifiable Janoshik COA, stocking everything from testosterone and ancillaries through to peptides, SARMs, and the full GLP-1 class including next-generation compounds like Retatrutide that most suppliers don’t carry.
Why Janoshik COA Matters
The Meso-Rx community has long understood that supplier-generated COAs have an inherent trust problem β the same company selling you the compound is also running the HPLC and issuing the certificate. Janoshik solves this: an independent laboratory runs the analysis, publishes the result with a unique batch code, and any researcher can verify it at verify.janoshik.com β without going through QSC. QSC cannot alter a Janoshik result after it’s published.
How to verify your QSC batch: Every QSC order includes a Janoshik batch verification code. Go to verify.janoshik.com β enter your code β see the independent laboratory’s HPLC and MS results directly. β₯99% purity + molecular weight confirmation on every compound.
Compounds in Stock at QSC
All compounds sold for in vitro laboratory research only.
Meso-Rx (mesomorphosis.com / meso-rx.com) is one of the longest-running anabolic steroid and performance enhancement forums, founded in 1999. It covers anabolic steroids, peptides, SARMs, ancillaries, and performance research in depth. Researchers and experienced users on Meso-Rx frequently discuss sourcing for research compounds including testosterone, anabolic steroids, peptides, and GLP-1 compounds. QSC is a US domestic research compound supplier that stocks many of the compounds discussed on Meso-Rx at β₯99% HPLC purity with Janoshik independent COA.
Where do Meso-Rx users buy research compounds?
Meso-Rx members discuss sourcing from domestic and international research compound suppliers. QSC (qscpeptide.com) is a US domestic option that stocks the compounds most discussed on Meso-Rx β testosterone, anabolic steroids (oxandrolone, winstrol, dianabol, primobolan), SARMs (LGD-4033, RAD-140, MK-677, Cardarine), peptides (BPC-157, TB-500, Ipamorelin, Sermorelin), and GLP-1 compounds (semaglutide, tirzepatide, retatrutide) β at β₯99% HPLC purity with Janoshik independent COA verification.
What is Janoshik COA and why does it matter to Meso-Rx researchers?
Janoshik is an independent third-party analytical laboratory that verifies the purity and identity of research compounds. Every QSC batch has a unique Janoshik verification code β any researcher can check the result at verify.janoshik.com. This independent verification is the gold standard in the research community, as it means QSC has no ability to alter or influence the published results. Meso-Rx members who prioritise sourcing from verified, independently tested suppliers consistently cite Janoshik COA as the key trust signal.
Does QSC stock anabolic steroids for research?
QSC stocks research-grade anabolic compounds including testosterone, oxandrolone, winstrol (stanozolol), dianabol (methandrostenolone), primobolan (metenolone), proviron (mesterolone), as well as SARMs (LGD-4033, RAD-140, MK-677, Cardarine) and ancillaries (exemestane, anastrozole, letrozole, clomiphene, tamoxifen, enclomiphene, cabergoline). All sold for in vitro laboratory research only, at β₯99% HPLC purity with Janoshik COA.
Does QSC stock peptides discussed on Meso-Rx?
Yes β QSC stocks all the major peptides discussed in Meso-Rx forums: BPC-157, TB-500, Ipamorelin, CJC-1295, Sermorelin, HGH, IGF-1 LR3, PT-141, Melanotan II, Semax, Selank, Epitalon, NAD+, MOTS-c, SS-31, FOXO4-DRI, GHK-Cu, and more β plus GLP-1 class compounds (semaglutide, tirzepatide, retatrutide) and novel pipeline compounds not widely discussed yet (ARA-290, Orforglipron, Cagrilintide, Humanin, Pinealon).
What makes QSC different from other sources discussed on Meso-Rx?
QSC differentiates on three factors consistently valued in the Meso-Rx research community: (1) Independent Janoshik COA β third-party verified, publicly checkable at verify.janoshik.com, not a supplier-generated in-house certificate; (2) US domestic warehouse β 2β4 business day delivery with no customs risk; (3) Novel compound access β Retatrutide, ARA-290, Orforglipron, Survodutide, and other pipeline compounds unavailable from most suppliers. 80+ compounds in one verified domestic source.
