Frequently Asked Questions
Everything you want to know about our peptides, shipping and orders.
Research peptides are synthetically produced peptide sequences intended for laboratory and analytical use — in fields such as molecular biology, biochemistry and pharmaceutical research. They go through no drug approval process and are reserved exclusively for scientific use, not for human consumption.
Each batch is checked by HPLC (High Performance Liquid Chromatography) for a purity of at least ≥98.9% — the baseline requirement for reproducible laboratory results.
Through an additional LC-MS analysis (Liquid Chromatography Mass Spectrometry), which unambiguously confirms molecular mass and sequence — independent of the plain purity measurement.
No — exclusively for scientific research purposes, neither for human nor veterinary use.
Every shipment leaves our warehouse in Germany, packaged discreetly. Depending on the destination, delivery is handled by DHL, DPD, Hermes or UPS.
Germany: 2–3 business days. Austria and Switzerland: 3–5 business days. Rest of Europe: 4–6 business days.
From €100 order value within Germany. Deliveries elsewhere in Europe carry a flat shipping fee of €9.90.
Credit card, plus the cryptocurrencies ETH, USDT and USDC, processed via DePay.
For long-term storage, −20 °C, dry and dark. For short-term use, 2–8 °C is sufficient. Details in our Storage Guide.
Yes — lyophilised peptides must be dissolved in a sterile solvent suitable for the protocol before use.
These three GLP-1-based peptides differ in how many receptors they address: Semaglutide targets one (GLP-1), Tirzepatide two (GLP-1 + GIP), and Retatrutide three (GLP-1 + GIP + Glucagon). Semaglutide and Tirzepatide are approved compounds; Retatrutide is currently in clinical trials. More detail: What is Retatrutide? · What is Tirzepatide? · What is Semaglutide?
GLP-1 (Glucagon-like Peptide-1) is an endogenous incretin hormone. Agonists mimic its effect: more insulin release, suppressed glucagon output, slower gastric emptying — together reducing appetite and stabilising blood sugar.
Add the sterile solvent slowly along the inner wall of the vial, then swirl gently — never shake. Typical concentration: 1–2 mg/ml. Full step-by-step process in our Application Guide.
