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.
