European Research Compound Catalogue
Welcome to SynthesisGear. You are looking at a curated catalogue of 127 products across five major manufacturers, designed for European researchers and performance athletes. We do not sell random stock; we stock specific, verifiable compounds from Magnus, Pharmacom, Genetic Labs, Prime, and Genopharm. The site is organised into seven clear categories, from Injectable Steroids to Cycle Packages, so you can navigate directly to the specific 53 active ingredients you need. Our platform supports seven European languages, ensuring clarity for users across the EU. We ship exclusively within the European Union, with a strict policy against US shipments. Payments are processed securely via major credit cards. This is a professional environment for sourcing research materials, prioritising accuracy, stock availability, and transparent logistical information for your procurement needs.
Catalogue Structure and Brands
The inventory is divided into seven distinct categories to help you locate specific compounds efficiently. The largest sections are Oral Steroids with 46 items and Injectable Steroids with 29 items, covering the core anabolic agents. Anti Estrogens (13 items) and Fat Burners (15 items) address supporting protocols. We also stock HGH & Peptides (6 items), PCT / Recovery (2 items), and pre-assembled Cycle Packages (16 items) for convenient ordering. You will find products from five established manufacturers: Magnus, Pharmacom, Genetic Labs, Prime, and Genopharm. Each product page lists the specific active ingredient, dosage concentration, and manufacturer. The 53 active ingredients are standardised across these brands, allowing you to compare prices and availability easily. We do not list discontinued or unverified brands. The categorisation reflects common research protocols, ensuring that PCT and supportive compounds are readily accessible alongside primary agents. This structure saves time and reduces the risk of ordering incorrect items.
Ordering, Payment, and Delivery
Our checkout process is streamlined for European customers. We accept payments via Visa, Mastercard, and American Express. No other payment methods, including PayPal or bank transfers, are supported. This ensures a secure and transparent transaction record for your purchases. Delivery is restricted to the European Union only. The United States is a closed market for our operations, and we do not ship to US addresses. Once your order is confirmed, it is processed and dispatched from our EU distribution centre. You will receive tracking information via email. The site is available in en, es, de, it, fr, pl, nl, allowing you to browse and order in your preferred language. If you encounter issues with your order or payment, contact [email protected] directly. We maintain a strict policy on shipping addresses to comply with regional regulations. Please ensure your billing and shipping addresses match your card details to avoid processing delays. This focused approach to logistics ensures reliable delivery within the EU.
Sourcing and Quality Control
We source our inventory exclusively from established manufacturers with verifiable production standards. The brands we stock, including Pharmacom and Magnus, are known for consistent product quality in the research compound market. We do not accept unknown or unverified stock. Each batch is associated with a specific manufacturer and lot number, which is documented in our internal records. This traceability is crucial for researchers who need to identify the source of their materials. We stock 127 products that represent the most requested active ingredients in the European market. Our inventory is updated regularly to reflect current availability. If a product is out of stock, it is clearly marked, and we do not accept pre-orders for unverified items. This policy ensures that you only purchase compounds that are ready for immediate dispatch. We prioritize reliability over speed, ensuring that every order contains the exact items listed. This approach builds trust with long-term customers who require consistent access to specific compounds for their research protocols.
