FAQ
Products & Lab Reports
What does research use only mean?
Everything we sell is supplied for laboratory research only, or RUO. It is not a medicine, not a supplement and not for use in humans or animals.
That is also why we do not answer questions about effects, dosing regimes or how to combine products. We can tell you what is in the vial, how pure it is and how to store it. Anything beyond that is outside what we are allowed to advise on.
Are all your peptides lyophilized?
Yes. Every PulsePeptides vial is lyophilized, or freeze-dried, which keeps the material stable in transit and in storage by protecting it from heat, moisture and oxidation.
A small amount of mannitol is added as a stabilizer during freeze-drying.
The one product in our range that is not a lyophilized peptide is BAC-Water.
What is BAC-Water?
BAC-Water is bacteriostatic water, supplied as 15 ml with 0.9% benzyl alcohol. It is a laboratory solvent, not a peptide.
How do you test quality?
Every batch is tested by Janoshik Analytical, an independent laboratory, to verify purity, identity and composition.
- HPLC for purity
- Bacterial endotoxins, with a limit of 10 EU per vial
Results for every active batch are published on this website, and you can verify them directly with Janoshik rather than taking our word for it.
Production runs under strict GMP quality and safety standards, with precise dosing and consistent quality in every vial.
Where do I find the lab report for my batch?
Your batch number is printed on the vial label.
HPLC and endotoxin results for every active batch are shown on the product page and on our Test Results page. The reports themselves are hosted by Janoshik, so you can check them at the source.
How should I store peptides?
Keep vials at 0 to 8 °C, in a cool, dry place, away from light.
Avoid repeated freeze and thaw cycles. Peptides containing Cys, Met, Trp, Asn or Gln, and copper peptides such as GHK-Cu, are more sensitive than the rest. Keep them in the original vial, away from light and moisture.
Do you offer raw peptide materials?
Our standard vials are lyophilized, but we can supply raw peptide powder on request for research or formulation projects.
These are handled as projects and may have a minimum order quantity. Send your project details to support@pulsepeptides.com.
What is the difference between lyophilized and raw powder?
Both are forms in which peptide compounds are supplied for laboratory research. They differ in physical state, and in how they behave in storage and handling.
Raw powder
Peptides in their pure, solid form, resembling a fine powder, usually produced by solid-phase peptide synthesis (SPPS). Raw powder is more exposed to air, moisture and temperature swings, so it needs more careful storage. Some researchers prefer it in order to avoid the excipients used in the lyophilisation process.
Lyophilized
Lyophilization, also called freeze-drying, removes water from a frozen solution under vacuum. What is left is a dry, porous cake that is easier to handle and to measure, and that has less stringent temperature and environmental requirements in storage.
Everything we sell as a standard vial is lyophilized. Raw powder is available on request.
Do you offer custom peptides and peptide synthesis?
Yes. We run custom peptide synthesis and project-based production for research and formulation development.
- Custom amino acid sequences
- Modifications such as acetylation or amidation
- Bulk peptide powder supply
- Analytical testing (HPLC, MS, COA)
- Confidential, project-based collaboration
Custom and made-to-order products are excluded from the right of withdrawal, because they are produced to your specification.
To discuss a project, write to support@pulsepeptides.com.
Do you supply bulk or wholesale quantities?
Yes. For large quantities, contact support@pulsepeptides.com directly and we will work out the details with you.
Payments
Which payment methods do you accept?
Four, all of them shown at checkout:
- Debit card
- Credit card
- Cryptocurrency, with a 5% discount on the order total
- Direct bank transfer, in EUR, GBP or USD
Which cryptocurrencies do you accept?
Bitcoin (BTC), Ethereum (ETH), Tether (USDT, on the Ethereum network), USD Coin (USDC), Binance Coin (BNB), Solana (SOL) and Litecoin (LTC). The current selection is shown at checkout.
Paying in crypto gets you 5% off the order total.
I paid with cryptocurrency. Why has my order status not changed?
Crypto payments are confirmed by hand, so they take longer than a card payment. For each blockchain we check how many network confirmations are needed before a payment counts as received. Once that threshold is reached and we have confirmed the incoming amount, your order moves into the normal processing time.
The amount due is always the amount shown at checkout, and that is the amount that has to arrive.
What reference should I use for a bank transfer?
Your five-digit order ID, and nothing else.
Please do not add product names or any other description. Extra wording can make your bank hold or reverse the transfer. The money then has to travel back to you before we can start again, which costs everyone a week.
Which currencies do you accept?
EUR, GBP and USD.
If your account is held in another currency, your bank or card issuer converts the amount at its own rate. Any conversion fee is theirs, not ours.
Do you accept PayPal?
No. PayPal is not available. You can pay by card, by cryptocurrency, or by direct bank transfer.
Are prices shown with VAT?
Yes. Prices include VAT where it applies, and the VAT is shown on your invoice.
Shipping
Where do you ship from?
All orders ship from inside the EU, from the fulfillment center closest to your delivery address.
What countries do you ship to?
We ship to the following countries.
- EU: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden.
- Outside the EU: Albania, Argentina, Australia, Bosnia and Herzegovina, Canada, Iceland, Moldova, Montenegro, Norway, Philippines, Saudi Arabia, Serbia, South Africa, Switzerland, Türkiye, Ukraine, United Arab Emirates, United Kingdom, United States.
Other countries are possible as well. A country not on this list is not automatically excluded from shipping.
Every country we can deliver to can be selected at checkout. If your country is not in the list there, we cannot currently deliver to it.
How much does shipping cost?
- Standard shipping, every country: €15.00
- Express shipping, every country: €55.00
Within Europe, standard shipping is free from €200.00, express shipping from €500.00. Both thresholds are order totals including VAT. Outside Europe there is no free shipping.
How long does delivery take?
Orders are processed within one to two business days. After dispatch:
- Europe: 3 to 11 business days standard, 1 to 5 express
- International: 7 to 25 business days standard, 2 to 7 express
These are estimates. Customs clearance and local postal services are outside our control and are the usual reason a parcel sits still for a few days.
Do you ship to PO boxes?
Yes, and to locker-style pickup locations such as DHL Packstations.
For a DHL Packstation, your Post Number (your personal DHL customer number) and the Packstation number both have to be part of the address. Without them the parcel cannot be delivered.
How can I track my order?
Once your order ships you get a confirmation e-mail with your tracking number and a link to follow the parcel.
Orders
What do the order statuses mean?
- Pending: we have received your order.
- On hold: your payment is not confirmed yet, or we have a question about the order.
- Processing: your order is being prepared, packed and dispatched.
- Back Ordered: something is out of stock. Your order ships once it is back in.
- Rejected: we were not able to accept the order.
- Cancelled: the order was cancelled by the customer.
- Completed: your order has been dispatched.
Can I modify or cancel my order?
Yes, as long as your order has not been processed and has not shipped. Orders are normally processed within one to two business days, so write to support@pulsepeptides.com as soon as you can, ideally straight away.
Once an order has been processed or dispatched we can no longer change or cancel it.
I entered the wrong shipping address. Can I change it?
Write to support@pulsepeptides.com immediately. We can update the address as long as the order has not shipped.
After dispatch we cannot change it. Giving us a correct and complete delivery address is your responsibility, and so is being there to receive the parcel. We are not obliged to redirect a shipment, to recover it, or to send it again to a different address. We do look at individual cases, but we cannot take on liability for them.
If we got the address wrong, we send your order again. No discussion.
I did not receive an order confirmation e-mail.
Check your spam or junk folder first.
If it is not there, the e-mail address on the order may have a typo in it. Write to support@pulsepeptides.com and we will resend the confirmation and check your order details.
One of my items is back ordered. What happens now?
A back-ordered item is temporarily out of stock, and your order ships once it is available again. If you would rather not wait, write to support@pulsepeptides.com and we will see what we can do for your order.
Can I combine multiple orders?
If you placed several orders in a short time, tell us as soon as possible. We can often combine them into one shipment, as long as none of them has been processed yet.
How do I contact support, and how fast do you reply?
By e-mail, at support@pulsepeptides.com. We are here Monday to Friday, 8am to 6pm London time.
Most messages get an answer within one business day. In a busy week it can take one to two.
Delivery Problems
My tracking has not updated in days. What should I do?
Tracking often goes quiet for several days in transit and during customs clearance, especially on international shipments. That on its own is not a sign that anything is wrong.
If it has not moved for a long stretch, open a delivery investigation with the carrier, and tell us as well. If your order is already past the timeframes for a lost parcel, see the entry on packages that have not arrived.
My package has not arrived. What now?
- Standard shipping: contact us if your order has not arrived within 30 days of dispatch.
- Express shipping: the same applies after 14 days from dispatch.
We then look at the case and offer either a free reshipment or a refund. Which of the two we can offer depends on the case.
If it is already obvious that the order will not arrive, for example because it was returned to sender, ask us to look at it earlier.
Tracking says delivered, but I did not receive my package.
From the moment a parcel is dispatched it is with the carrier. Open a delivery investigation with them directly. They are the only ones who can search for it, check who signed, and find out where the driver left it.
Tell us too. We look at each case individually and can contact the carrier ourselves where that helps. If the problem turns out to be on our side, you get a full refund.
My package is held or seized by customs.
Inside the EU, if customs seizes your parcel, we replace the goods in full, at no cost to you.
Outside the EU, we cannot offer a refund or a reshipment for parcels that are held, refused or seized. This includes European countries that are not EU member states.
Checking whether the products you order may lawfully be imported into your country is your responsibility.
Who pays customs duties and import taxes?
The recipient. Customs duties, import taxes and handling fees are charged by the destination country and are not included in the product price or the shipping cost.
All orders ship from inside the EU.
My order arrived damaged or incomplete.
Write to support@pulsepeptides.com within 7 days of delivery. Include your order number and photos of the problem.
Damaged goods are refunded in full. Where the damage is entirely on our side we will send a replacement instead, if you prefer that.
Returns & Refunds
Can I return a product?
Our vials are sealed for hygiene and sterility. The flip-off cap and the rubber stopper are that seal. Once either one is opened, punctured or damaged, the vial cannot be returned. Sterility and batch integrity cannot be restored, so the product can never be sold again.
While the seal is intact you have a right of withdrawal, described in the next entry.
Damaged, defective or incorrect goods are a separate case and are refunded in full.
Do I have a right of withdrawal?
As a consumer in the EU you have 14 days to withdraw from your purchase, counted from the day your order arrives. It applies to unopened, sealed goods.
Three things to know:
- The right of withdrawal ends once the seal is removed, because the goods can no longer be returned for health protection and hygiene reasons.
- You pay the cost of sending the goods back.
- Peptides have to be kept at 0 to 8 °C. If returned goods were kept outside those conditions, we deduct the resulting loss in value.
Custom synthesis and other made-to-order products are excluded, because they are produced to your specification.
How long does a refund take?
We review each refund individually and pay it out as fast as we can. How long it then takes to reach you depends on your bank, card issuer or wallet.
