Second order, same setup. GHK-Cu + Retatrutide, NaCl 2ml with every vial. Everything cleanly labeled, batch number on it. Solid.
Zweite Bestellung, Setup wie gehabt. GHK-Cu + Retatrutide, je 2 ml NaCl pro Vial. Alles ordentlich beschriftet, Chargennummer drauf. Läuft.

Discreta, veloce, affidabile. Esattamente quello che si aspetta da un brand serio.
I didn't know what to expect from my first order, but everything went great. The instructions arrived by email, the package came quickly — and everything came together without any hassle.
Nisam znao što očekivati od prve narudžbe, ali sve je prošlo super. Upute su stigle mailom, paket brzo — i sve se spojilo bez muke.
Hi. Second time ordering from you guys. This one arrived in 3 days. The packaging is cool, easy to keep it in my fridge vertically inside the box so the light doesn’t penetrate.

Didn't expect them to have their own app — but they do, and you actually use it. Notifications come in before you even check your email. Tracking, instructions, everything in one place. You can count on this.
Hab nicht erwartet, dass die eine eigene App haben — aber die haben eine, und man nutzt sie wirklich. Benachrichtigungen kommen rein bevor man überhaupt die Mails checkt. Tracking, Anleitungen, alles an einem Ort. Darauf kann man sich verlassen.
Great experience overall, very smooth process and great customer support!

Purity on the report was above 99%, same as the label. Reordered twice since.

The 30 mg format is well priced for longer protocols. Same purity as the 10 mg.
A 30 mg-os kiszerelés jó árú hosszabb protokollokhoz. Ugyanaz a tisztaság, mint a 10 mg-nál.
Restock notification worked — got the email and ordered the same day.

Every batch is analysed by HPLC, which separates and measures the compound — so purity of ≥99% and identity are verified for the exact lot you receive, rather than taken on trust.
Yes — a Certificate of Analysis (CoA) is available on request for every product and batch, documenting purity and identity for the specific lot you receive. For selected products the report can be opened directly from the product page and the Research library; for all others, contact us with your order or lot number.
Yes. Every vial carries a lot/batch number for full traceability back to its analysis and production record.
Independent third-party analysis is carried out by Janoshik Analytical. Each report carries a task number that can be verified on the laboratory's own website.
Refrigerate at 2–8°C on receipt — do not freeze. Lyophilised powder remains stable for up to 24 months; once reconstituted, keep at 2–8°C, away from light, and use within 30 days.
