All research peptides
The complete LYSENTA catalogue. Every batch is lab-verified to be ≥99% pure, with a Janoshik COA and fast Express delivery.
The full LYSENTA range of research peptides in one place — from recovery and metabolism to growth hormone research, longevity and skin. Each batch has been independently tested by Janoshik Analytical to ensure ≥99% purity, with a publicly available lab certificate for each batch number. For laboratory and research purposes only.
Buying peptides for research: what should you look out for?
When buying research peptides, look out for four things: verified purity, a batch-specific certificate, traceability to the batch number, and reliable delivery within the EU. Research materials are only useful if you know exactly what is in the vial — and you can only be sure of that once an independent laboratory has analysed it.
Purity is determined using HPLC (High-Performance Liquid Chromatography), which separates the components of a sample and shows what percentage is actually the target peptide. Mass spectrometry then confirms the molecular identity and the exact molecular weight. Without these two measurements, a purity claim is nothing more than a figure on a website.
LYSENTA applies a threshold of ≥99% and has every single batch tested by Janoshik Analytical. The batch number on the label refers to the corresponding certificate, so that you can trace exactly which batch you had at a later date — the basis for reproducible work. Read about how we organise that process on the science page.
How much does a research peptide cost?
The price of a research peptide is determined by three factors: the scale of synthesis, the purity threshold and the independent laboratory testing carried out on each batch — not by the size of the vial alone. A longer amino acid chain is more complex to synthesise, and every additional percentage point of purity requires extra purification steps. This accounts for the bulk of the price difference within a product range.
You should therefore never compare prices based on the price per vial, but rather on the price per mg: divide the price of the vial by the number of milligrams it contains. A 10 mg vial costing €99 works out at €9.90 per mg. This way, you can see straight away that a cheaper vial with a smaller content isn’t automatically better value. The price per mg is calculated and displayed on every product page, alongside the contents and availability.
If a product is significantly cheaper elsewhere, the difference almost always lies in one of two things: lower purity, or the absence of a batch-specific COA. These are precisely the two variables that determine whether your research is reproducible. With a bundle, the saving can be as much as 15%, and above a certain threshold, delivery charges are waived — see below.
Peptide blends and mixes
A blend combines two or more peptides in a single lyophilised vial, so that they are reconstituted together rather than separately. In research, this is practical when combinations are studied as a whole; the total quantity in a blend is the sum of the individual components, which means that the price per mg is calculated slightly differently than for a single peptide.
The range includes, amongst others, the TB-500 + BPC-157 Wolverine blend, the CJC-1295 no DAC + Ipamorelin blend, and the broader KLOW and Glow blends. CJC-1295 no DAC (Mod GRF 1-29) is also available separately.
The same requirements apply to each blend as to the individual peptides: one batch number, one Janoshik certificate, ≥99% purity per component. The exact composition and the breakdown by component are listed on the product page.
Research categories in the shop
The range is categorised according to the research area in which a peptide is being studied, so that you can quickly find the right group:
Recovery & Tissue — Recovery & Healing, featuring peptides such as BPC-157 and TB-500.
Metabolism — Fat Loss & Metabolism, including Retatrutide and MOTS-C.
Growth Hormone Research — Muscle Growth & Growth Hormone, featuring CJC-1295 and Ipamorelin.
Longevity — Anti-ageing & Longevity, featuring Epithalon and NAD+.
Skin — Skin & Pigmentation and Skincare & Serums.
Other research — Cognition & Focus, Immune System, Sleep & Relaxation, and Hormones & Fertility.
If you’re working with lyophilised vials, you’ll find the relevant supplies — bacteriostatic water, syringes and wipes — under ‘Lab & Accessories’. New to peptides? Start by finding out exactly what peptides are, or calculate your dilution using the reconstitution calculator.
Ordering and delivery within the EU
LYSENTA charges €9.95 for delivery within the EU, and delivery is free on orders of €150 or more. Parcels are sent via PostNL, are discreetly packaged and come with a tracking code; a parcel is usually delivered within 1–3 working days. The countries and current rates are listed in the delivery policy.
Each consignment is accompanied by a batch-specific certificate linked to the batch number on the label. Lyophilised peptides are stable enough at room temperature for transport; upon receipt, store them in accordance with the storage instructions on the product page — typically at −20 °C for long-term storage.
All products in this shop are supplied exclusively for laboratory and research purposes. They are not intended for human or animal consumption, are not marketed as medicinal products, and no health claims are made in relation to them.
Frequently Asked Questions
How much does a research peptide cost at LYSENTA?
This varies depending on the peptide: the price is determined by the synthesis scale, the purity threshold and the independent laboratory testing carried out on each batch. Compare prices per mg (vial price divided by the content in milligrams) rather than by vial price — this is calculated on each product page, along with current availability.
Can you buy peptides online in the Netherlands?
Research peptides are supplied in the Netherlands on a research-only basis: exclusively for laboratory and research purposes, not as a medicinal product and not for consumption. LYSENTA delivers within the EU, with a batch-specific Janoshik certificate included with every consignment. This is general information and does not constitute legal advice.
What is a peptide mix or blend?
A blend combines two or more peptides in a single lyophilised vial, so that they are reconstituted together. The quantity stated is the total for all components. The range includes, amongst others, the TB-500 + BPC-157 Wolverine mix, CJC-1295 (DAC-free) + Ipamorelin, KLOW and Glow.
Why do prices vary so much between different peptides?
This is mainly due to the complexity of the synthesis and the number of purification steps required to exceed the 99% threshold. A longer amino acid chain requires more steps, and every additional percentage point of purity demands further purification. On top of that, there are the costs of the independent laboratory test for each batch.
What is the purity of the peptides in the shop?
LYSENTA applies a threshold of ≥99%, determined by HPLC and confirmed by mass spectrometry by Janoshik Analytical. Each batch number on the label is linked to a publicly available certificate of analysis, ensuring that every batch can be traced retrospectively.
Are these peptides intended for human use?
No. All peptides and accessories in this shop are offered exclusively for laboratory and research purposes and are not intended for human or animal consumption.
