# Quality and laboratory testing **URL:** https://www.gavau.lt/en/pages/kokybe-ir-laboratoriniai-tyrimai --- Quality and laboratory testing — GAVAU.LT GAVAU.LT – the official authorised distributor of NPCRIZ peptide bioregulators in Lithuania and the Baltic states. The Institute of Bioregulation and Gerontology (NPCRIZ) is a scientific institution founded in 1992 by Prof. Vladimir Khavinson. All our trade is based on a direct relationship with the manufacturers, compliance with EU regulations and the manufacturers’ own quality control systems. 1. Direct supply from the manufacturer NPCRIZ (Institute of Bioregulation and Gerontology) – all peptide bioregulators (cytomaxes, cytogens, GPL complexes) are supplied directly by the manufacturer. There are no intermediaries between GAVAU.LT and NPCRIZ. FOHOW Bioscience (Zhuhai Yupintang Biological Science and Technology Co., Ltd., China) – the full FOHOW product catalogue is supplied directly through the official importer UAB „Xinshidai". Foherb – a Chinese manufacturer of herbal preparations, with GMP certificates and EU declarations of conformity. MyRealWay – a cosmetics manufacturer that uses NPCRIZ peptide formulations. 2. EU regulatory compliance All food supplements comply with Directive 2002/46/EC (supplements – the presentation of food products) and Regulation EC No 1924/2006 (health claims on food supplements). The compositions match the manufacturer declarations and are stated on each product label. Retail trade is carried out under Lithuanian law – every supplement sold is registered with the VMVT (the State Food and Veterinary Service). Cosmetic products (MyRealWay) comply with Regulation EC No 1223/2009 – a safety report (CPSR) is provided. 3. Manufacturers’ quality control NPCRIZ peptide bioregulators The Institute of Bioregulation and Gerontology (NPCRIZ) is a scientific institution founded in 1992 by Prof. Vladimir Khavinson. Over 30+ years of work: Published 800+ peer-reviewed scientific publications on peptide bioregulation. Registered 200+ patents for peptide isolation and synthesis methods. Carried out clinical studies with thousands of patients, including gerontological research. Production takes place in GMP-certified facilities; every batch goes through internal quality control: HPLC analysis, microbiological testing, heavy metals screening. FOHOW Bioscience The FOHOW manufacturer (Zhuhai Yupintang Biological Science and Technology Co., Ltd.) holds: A GMP certificate for the manufacture of natural products. ISO 22000 (food safety management system). A HACCP system for risk management. Batch certificates, available on request. 4. Important note: GAVAU.LT DOES NOT DISTRIBUTE injectable research peptides GAVAU.LT specialises in oral / sublingual peptide bioregulators – a scientific category created by NPCRIZ and underpinned by its research. These are NOT injectable research peptides (such as BPC-157, TB-500, CJC-1295, GHK-Cu, Ipamorelin, Retatrutide, MOTS-c, Tirzepatide and the like). Injectable research peptides are a separate market category in which the usual practice is batch HPLC/COA certificates, because the products are most often sold as „research chemicals" without food supplement status. We do NOT sell such products – they require a different form of regulation. NPCRIZ peptide bioregulators are sold as food supplements on the EU market under the applicable regulation. Instead of batch „research-grade" COAs, NPCRIZ provides manufacturer declarations of conformity and composition analysis in line with the EU supplements directive. 5. Our commitment to transparency A clear category: we do not try to present our products as something they are not. Peptide bioregulators and injectable research peptides are different classes of product with different research backgrounds. Source documentation: on request, we can provide the manufacturer documents (GMP certificate, batch declaration of conformity). Clear pricing: there are no hidden charges; the delivery price is shown before payment. 30-day returns: unopened products can be returned under EU consumer rights. Personal consultations: we can help you choose the product best suited to your particular situation. 6. Frequently asked questions about quality Will I receive an HPLC/COA batch certificate with my order? Not automatically. NPCRIZ peptide bioregulators are sold as food supplements – a batch certificate is not standard practice for this category. On request, however, we can obtain the manufacturer’s conformity documents for a specific batch. Are the products tested independently? NPCRIZ production takes place in GMP-certified facilities, where every batch goes through an internal quality control process (HPLC, microbiological and heavy metals testing). Independent third-party testing of individual batches is not common practice in the food supplement category, but all manufacturers are audited by EU market surveillance authorities. Why are your products cheaper / more expensive than comparable ones? Our prices reflect direct supply from the manufacturer (with no intermediary mark-up). Even so, peptide bioregulators are not cheap – they are food supplements in a specialised category. 7.
