Built by researchers tired of guessing what was actually in the vial.
IGF1 Shop exists because the gap between "research peptides" sold online and what laboratory work actually demands is enormous. We're closing it — one lot, one assay, one Certificate of Analysis at a time.
The problem we set out to solve.
Most online peptide vendors release product on the strength of a vendor-supplied COA they have never independently verified. Some don't bother with a COA at all. The gap between what is on the label and what is in the vial can be ten, twenty or thirty percentage points of purity — and that's before counting endotoxin contamination, mass-spec deviations, and lot-to-lot drift. If you're running an experiment that depends on a known input, none of that is acceptable. You shouldn't have to send every shipment to a contract lab before you can use it. So we built a vendor that does that step for you, on every batch, before the listing goes live.
Four operating principles, no exceptions.
Everything else flows from these four. They're not policies — they're the conditions under which a batch becomes a release.
Independent verification
Every lot we receive from synthesis is sent to a separate ISO/IEC 17025 accredited lab for HPLC, mass spectrometry and endotoxin assay. We pay for the testing. If the lot doesn't clear, it doesn't ship — full stop, no downgrade SKU, no "research grade" override.
Per-lot COA, never generic
The COA you receive corresponds to the exact vial in your hand. Lot number, release date, raw chromatogram, mass-spec trace and endotoxin reading — all on one signed PDF traceable back to the lab that ran the assays.
Three audited synthesis partners
No re-labeling, no mystery sources. Every compound traces to one of three GMP-aligned facilities we audit annually. We can name the facility for any compound you ask about under NDA — and we know who made the lot we shipped you, by lot number.
Pyrogen-free packaging
Vials are filled, capped and labelled in HEPA-filtered environments using depyrogenated glassware. Outer packaging is tamper-evident; insulated mailers protect the cold chain. Reshipment guaranteed if a package arrives damaged or compromised.
The release floor we operate to.
Concrete commitments, not marketing language. These are the numbers a buyer can hold us to and verify against any individual COA.
Synthesis in Switzerland and Slovenia. Verification in two independent labs.
We are not a single facility — we are a release decision built on top of separately-owned partners. Each link in the chain is documented, audited, and replaceable if the partner stops meeting our standards.

Who we ship to — and who we don't.
Our compounds are sold strictly for in-vitro laboratory research. We are not a clinic, a pharmacy, a supplement vendor or a beauty brand. The line is firm because the regulatory category and the storage handling are different.
Yes — we ship to
- Academic research groups (universities, institutes)
- Contract research organisations (CRO)
- Biotech startups validating analytical workflows
- Independent researchers running in-vitro studies
- Public-sector laboratories and government research
- Pharmaceutical companies for assay development
No — we don't ship to
- Anyone purchasing for human consumption
- Anyone purchasing for animal consumption
- Veterinary, livestock or agricultural use
- Cosmetic, food or supplement formulation
- Resellers without documented scientific use
- Buyers in restricted jurisdictions (the order page will tell you)
What arrives when you place an order.
The exact contents of every package, regardless of order size or destination. Free shipping on orders over $59; carriers are UPS Next Day Air (US) and DHL Express Worldwide (international, 5 business days).
Lyophilized peptide
Tamper-evident vial with the released lot. Sealed under inert atmosphere where the sequence requires it.
Lot-specific COA (PDF)
Signed by the contract lab. Contains the chromatogram, the mass spectrum, the LAL kinetic curve and the release decision.
Reconstitution guide
Recommended diluent (BAC water vs. saline vs. acetic acid), volume per concentration, and the storage profile for the reconstituted aliquot.
Insulated mailer
Cold-chain protected, padded, with airbags. Lyophilized peptides ship at ambient — sealed and stable for several weeks above freezing.
Tracked shipping
UPS Next Day Air (US, 48 h) or DHL Express Worldwide (international, 5 business days). Tracking number sent the same day the label is printed.
Reshipment guarantee
If the package arrives damaged, broken, or compromised — send a photo and we ship again, no quibbling, no return required.
