Do you ship research peptides to the United States, Canada and Australia?

Yes. We ship to all 50 US states, Canada and Australia via DHL Express cold-chain delivery. USA delivery is guaranteed within 3 business days; Canada is typically 3–4 business days; Australia is typically 5–7 business days after dispatch.

How long does DHL Express delivery take?

USA delivery is 3 business days after dispatch. Canada usually takes 3–4 business days. Australia usually takes 5–7 business days. Dispatch happens every Monday and Wednesday.

Is the cold chain maintained for international DHL shipments?

Yes. USA, Canada and Australia shipments use refrigerated insulated foam containers with phase-change cooling material rated for up to 96 hours of cold-chain integrity at 2–8 °C.

What does DHL shipping cost to the USA, Canada and Australia?

USA is £24.99. Canada is calculated proportionally at 1.2× the USA DHL base and rounded to £29.99. Australia is calculated proportionally at 1.6× the USA DHL base and rounded to £39.99. The exact freight is shown before payment.

What are research peptides and how are they used?

Research peptides are high-purity synthetic compounds manufactured exclusively for in-vitro and laboratory research. They are used by researchers, academic institutions and certified labs to study mechanisms of action, stability profiles, formulation development, and receptor binding behaviors. They are not pharmaceutical drugs and are not intended for diagnostic, therapeutic, or human/animal consumption purposes.

Are Synedica Labs products legal to purchase?

Yes. Our products are sold strictly for laboratory research and development applications and are legal in the regions we ship to under research-chemical regulatory frameworks. By purchasing, you confirm that you are a qualified researcher or representative of a research institution and will use the materials exclusively for non-clinical R&D purposes.

How is product purity verified?

Every batch is independently tested by third-party analytical labs. We provide a Certificate of Analysis (COA) per lot, including HPLC purity verification (typically ≥99%), mass spectrometry confirmation, and endotoxin testing. COAs are available on request for any order.

How fast is shipping and what does it cost?

USA: DHL Express guaranteed 3 business days — £24.99. Canada: DHL Express 3–4 business days — £29.99 (1.2× USA base). Australia: DHL Express 5–7 business days — £39.99 (1.6× USA base). UK: Royal Mail Tracked 48 (£7.99) or Tracked 24 (£15.99). EU: EDP/Chronopost (£15.99 std, £23.99 express). All shipments refrigerated cold-chain. Dispatch every Monday & Wednesday.

How should research peptides be stored?

Most lyophilized (powder) peptides are stable at room temperature for transit but should be stored long-term at 2-8°C (refrigerator). Reconstituted peptides should always be stored refrigerated and used within 30 days. Avoid repeated freeze/thaw cycles. Detailed storage protocols are provided with each kit.

Do you ship discreetly?

Yes. All shipments use plain external packaging with no branding or product disclosure on the outer parcel. Internal documentation includes only research labelling and the COA. Tracking is provided to all customers.

What payment methods do you accept?

We accept cryptocurrency only: Bitcoin (BTC), Ethereum (ETH), Tether (USDT), and Litecoin (LTC). Live GBP conversion at checkout via CoinGecko. Your payment data is never stored.

How does the Buy 3 Get 1 Free combo work?

Add 3 units of any product to your cart, and the 4th unit of the same product is automatically free at checkout. You can mix products — each product qualifies independently for its own 3+1 deal.

What is your refund policy?

We offer a 30-day money-back guarantee on unopened products. If a kit arrives damaged or fails QC inspection on receipt, contact us within 7 days and we will replace or refund immediately.

Research Reference

The metabolic peptide ladder — Semaglutide → Tirzepatide → Retatrutide

Understanding receptor coverage helps researchers select the right compound for their protocol stage.

①

Semaglutide — GLP-1

Single-receptor agonist. The standard entry point for new metabolic research protocols. Effects one receptor pathway in metabolic studies.

From £95 · View kit →

②

Tirzepatide — GLP-1 + GIP

Dual-receptor agonist. The intermediate step when single-pathway tolerance has been observed. Provides broader mechanistic coverage.

From £106 · View kit →

③

Retatrutide — GLP-1 + GIP + Glucagon

Triple-receptor agonist. The most advanced compound in the class — ideal when dual-agonist protocols have plateaued. Broadest receptor profile.

From £130 · View kit →
