They play crucial roles in many biological processes, including hormone regulation, immune response, and cell signaling. Research peptides are synthetic versions used in laboratory settings to study these biological mechanisms.

Crystal Peptides: 5–9 units of the same product receive 10% off, 10–19 receive 20%, and 20 or more receive 30%. Checkout confirms eligibility and any permitted combinations.

Crystal Peptides lists vials, nasal solutions and capsules. Check the exact product for its strength and status; a Coming soon listing is not yet available to order.

Keep the bottle closed and follow its labelled temperature, expiry and moisture precautions. Do not apply storage instructions for a reconstituted vial to capsules. If the seal is damaged or the contents change unexpectedly, keep the packaging and contact support.

The first number is the total amount in the bottle, not in each spray. At a nominal 60 sprays, 10 mg/10 ml corresponds to about 167 mcg per spray; 500 mg/10 ml to 8.33 mg. Actual pump output needs separate validation.

No. Absorption depends on the compound, formulation and device. Research on one nasal preparation cannot validate every peptide or prove a brain effect. A receptor mechanism alone is not evidence that a nasal product works in humans.

Follow the storage conditions and expiry for the exact formulation. Unopened shelf life, time after opening and transport temperature are different questions. Stabilizers may help, but a purity result alone does not establish microbiological quality or a room-temperature shelf life.

Strength is stated per capsule unless the label says otherwise; the capsule count is separate. For blends, read each ingredient amount. Some products in this category are small molecules rather than peptides, so the category name does not define their chemistry.

No. Digestion and the intestinal barrier can limit absorption. Evidence depends on the exact compound and formulation, and a local intestinal effect is different from systemic absorption. Results for one product cannot establish the performance of the whole capsule range.

No. Bacteriostatic water is not included automatically and, when listed, must be purchased separately. Whether any solvent is suitable depends on the validated laboratory method and product documentation. We cannot provide reconstitution, injection, or administration instructions.

Bacteriostatic water is a separately listed laboratory accessory whose label identifies its composition and intended handling. Its suitability for a particular validated research method must be determined from the relevant product documentation and your institution-approved protocol. We cannot recommend a solvent or provide reconstitution, dosing, injection, or administration instructions.

No. We can only compare factual information currently published in the catalogue: product name, format, strength, price, availability, and exact linked documentation. We cannot recommend a product or stack for a person or goal, advise on interactions or human use, predict outcomes or timelines, or describe one option as safer, stronger, or more effective without an approved published claim.

Products are offered only for lawful laboratory research and are not intended for human, medical, or veterinary use. Laws, import rules, permits, and allowed activities can vary by destination and may change. You are responsible for checking the requirements that apply to your destination and intended lawful research activity; we cannot provide individual legal advice.

For unopened freeze-dried vials, follow the temperature and expiry stated for the exact product and batch. Protect them from light and moisture. After opening or laboratory preparation, the original unopened shelf life no longer applies automatically.

Do not continue with a laboratory procedure when a sample appears abnormal or does not meet the approved method's acceptance criteria. Keep the vial and label, take clear photographs, and contact support with the product name, batch information, storage history, and order number. We cannot troubleshoot reconstitution or provide administration instructions.

A report is verified only against the exact product, strength, batch or lot, and report type shown in the published record. If no exact match is published, we will say that no linked report was found for that exact combination; this neither proves nor disproves quality. We do not make universal purity or all-batch testing claims.

This FAQ does not approve independent testing, reimbursement, store credit, replacement, or refund. Contact the official support address listed on the site before arranging any testing. Only explicit written confirmation for the exact case can establish whether anything is approved; without it, do not assume reimbursement, credit, replacement, or refund.

Report the issue through an official support channel and provide the order reference and requested evidence.

• If the original shipment is confirmed as not delivered, lost, or seized by customs for reasons outside your control, we send one replacement shipment at no extra cost. A customs hold, inspection, or tracking delay alone is not confirmed non-delivery.
• If that replacement shipment is also confirmed as not delivered for reasons outside your control, we issue a full refund for the affected goods. We do not send a second replacement shipment.
• A wrong, missing, broken, or damaged item must be reported within 7 days of delivery with a full, continuous unboxing video. Once verified, we send the missing, correct, or replacement item, including shipping, at no cost.

The non-delivery process does not apply to customer-caused failures or an order or destination prohibited by applicable law. Mandatory statutory rights are unaffected.

Available couriers and methods, shipping price, cash-on-delivery availability or fee, any free-shipping threshold, and estimated delivery time depend on the destination and exact delivery route, such as address, office, or locker. Enter the delivery details at checkout to see the current options and final calculation before confirming. Checkout estimates are not guaranteed delivery dates; if an option or threshold is not shown for that route, do not assume it applies.

Available payment methods depend on the order, destination, and current checkout configuration. Use only a method shown as selectable at checkout; that screen is the current source of truth. Never send card numbers, bank login details, one-time codes, wallet private keys, or seed phrases in chat.

You may ask support to review a change or cancellation before fulfilment, but the request is not completed or guaranteed until the team explicitly confirms it. Do not make a manual payment requested only in chat or share card, bank, or wallet credentials there. If a balance or refund is required, follow only the official order or payment flow issued after the review.

Report a wrong, missing, broken, or damaged item through an official support channel within 7 days of delivery. Keep all packaging and record a full, continuous unboxing video that clearly shows the unopened parcel, shipping label, the entire opening, all contents, and the issue. Photographs, labels, and batch or lot details may be requested as supporting evidence, but they do not replace the video. Once the evidence is reviewed and the issue is verified, we send the missing, correct, or replacement item, including shipping, at no cost. Mandatory statutory rights are unaffected.

Order creation, payment receipt or confirmation, processing, dispatch, and a customer-usable final carrier tracking number or link are separate states. When an authenticated order page is available to you, its current status is authoritative; a dispatch status alone does not mean that final customer tracking is available. No fixed dispatch time is promised here.

Follow the exact payment instructions and current status shown for that order. A payment reference identifies the transfer or transaction; it is different from the order reference that identifies the order. For an initial review, provide only the order reference, the payment reference if displayed, and the visible error or status. Never send a full bank statement, account login, card details, private keys, recovery phrase, or wallet credentials in chat; no universal expiry or processing time is promised.

We provide a date only when a confirmed estimate exists for the exact product, strength, and format. If no exact estimate is published, there is no confirmed restock date, so we will not invent one. Use a stock-notification option if it is currently available on the product page.

Eligibility and stacking can depend on the products, quantities, account, promotion, payment method, and current checkout rules. The final checkout calculation and displayed order breakdown determine which discounts or rewards apply and in what amount. Do not rely on a previous order or a general FAQ as a guaranteed combination.

Checkout revalidates current eligibility, scope, validity, and whether combinations are allowed when the order is calculated. A rejected coupon, reward, or promotion does not create an automatic right to reissue, combine, or apply it manually. For review, share only the exact visible error text and the order reference, never account or payment secrets.
