Frequently Asked Questions

Answers about COAs, Janoshik testing, shipping, ordering, payment, storage, and research-use-only policies.

How much is shipping?

FREE shipping on every order. No minimum, no exceptions. Orders ship within 1-2 business days.

Are your peptides tested?

Every documented batch is verified through independent third-party testing. BatchTrace: scan vial QR → match batch code → verify Janoshik report. COAs are available on each product page and in our COA & Batch Verification Ledger.

How long does shipping take?

Orders ship within 1-2 business days. Standard delivery takes 3-5 business days.

What payment methods do you accept?

Current checkout options include credit card payment and credit/debit card invoice request. Available payment methods may vary by order and compliance requirements.

Is packaging discreet?

Yes. All orders ship in plain, unmarked packaging for product protection and privacy — no product names or descriptions on the exterior. There is a small chameleon sticker because we couldn’t help ourselves, but it doesn’t reference any contents.

What is your refund policy?

Due to the nature of research materials, we cannot accept returns. If there’s an issue (damaged, defective, or missing), contact us within 48 hours and we’ll make it right.

Where do you ship?

We ship to all 50 US states. International shipping is not available at this time.

How do I contact support?

Email [email protected] or use the chat widget on our site — you’ll probably meet Kai, our AI assistant. He’s fast, friendly, and surprisingly knowledgeable about peptides. If he can’t help, a real human will follow up within 24 hours.

Can I track my order?

Yes — you’ll receive a tracking number via email once your order ships. You can also track directly on the carrier’s website.

Quality & Sourcing

How we source, test, and maintain the standards behind every vial

What are research peptides?

Short chains of amino acids used in laboratory and preclinical research. They’re tools for studying biological processes — from tissue biology to metabolic pathways to cellular signaling. Every peptide we sell is for research use only.

How do I verify purity?

Documented batches are independently tested by Janoshik Analytical. We publish batch-specific COA rows with HPLC purity, mass spectrometry identity, amount, endotoxin, heavy metals, or other screens where those tests were ordered. BatchTrace: scan vial QR → match batch code → verify Janoshik report through our COA & Batch Verification Ledger and the linked Janoshik records.

How should peptides be stored?

Lyophilized research materials should be handled according to qualified laboratory SOPs, institutional requirements, and batch-specific documentation. Protect materials from light, moisture, contamination, and repeated temperature cycling as appropriate for the research protocol.

Where are your peptides sourced?

We work with ISO 9001 certified manufacturers. Yes, synthesis happens in China — because that’s where it happens for the entire industry. The difference is verification. Every batch gets independently tested before we stock it.

How do you maintain batch consistency?

We test incoming batches separately, maintain batch documentation, and add packaging or supplier-cycle notes when they matter. If a supplier’s quality dips, we switch. Our catalog is curated, not comprehensive — we’d rather sell verified products than products we can’t vouch for.

01What if I accidentally use a research peptide for non-research purposes?

Misuse of research peptides for non-research purposes can carry significant legal and ethical consequences. It's crucial to strictly adhere to the 'for research purposes only' designation to avoid such issues.

02What If You Need Peak GH Output Above All Else?

Use hexarelin for short-term protocols (≤10 days) where maximum GH release is the primary outcome. Accept that cortisol, prolactin, and aldosterone will all rise significantly, and plan for receptor desensitisation if dosing extends beyond two weeks. Hexarelin produces GH peaks 30–50% higher than ipamorelin at equivalent doses, but the secondary endocrine effects and tachyphylaxis risk make it unsuitable for most experimental designs. If your protocol examines a single acute GH pulse and its downstream effects within 24–48 hours, hexarelin is the right tool. For everything else, it introduces more variables than it solves.

03What If Cost Per Milligram Is the Primary Constraint?

Snap-8 ($0.45–0.75/mg) and Melanotan II ($0.60–1.00/mg) are the most economical options for sustained multi-week studies. TB-500 costs 3–5× more per milligram, and while BPC-157 sits in the middle range ($1.20–1.80/mg), its broader mechanism often justifies the premium. If your study design suits Snap-8's neurotransmitter-focused pathway, cost efficiency favors it decisively. Just confirm the biological endpoint you're measuring actually involves acetylcholine modulation.

04What If I'm Designing a Study on Metabolic Substrate Availability and Receptor Signaling Simultaneously?

Combine Lipo-C with a peptide in a factorial design: one group receives Lipo-C alone, one receives the peptide alone, one receives both, and one receives neither. This isolates substrate-level effects from receptor-mediated effects and tests whether the two mechanisms are additive or synergistic. For example, pairing Lipo-C with a GLP-1 agonist in a hepatic steatosis model would reveal whether substrate provision (Lipo-C) enhances the metabolic response to receptor activation (GLP-1 agonist). Measure both pathway-specific endpoints: SAMe/SAH ratio and phosphatidylcholine content for Lipo-C, and cAMP levels or insulin secretion for the peptide.

05What If I'm Using BPC-157 for Tendon Repair — Does Adding AHK-Cu Help?

Yes, but only if collagen cross-linking is a limiting factor. BPC-157 accelerates angiogenesis and capillary formation, which delivers oxygen and nutrients to the injury site. But it doesn't directly improve the structural integrity of newly synthesised collagen. That's where lysyl oxidase comes in. If copper availability is low, the collagen deposited during BPC-157-mediated repair will be poorly cross-linked and mechanically weak. AHK-Cu addresses that gap by restoring lysyl oxidase activity, which increases tensile strength in healing tendons. Research from the Journal of Orthopaedic Research found that combining copper peptides with angiogenic growth factors improved collagen tensile strength by 31% compared to growth factors alone.

Research context

Read sources and limitations before applying a claim.

Research Context: Not for Human Use

It’s critical to understand that research peptides are for laboratory use only. They are not approved for human consumption, injection, or therapeutic use. All research peptide use must take place in appropriate laboratory settings with proper training, equipment, and adherence to institutional guidelines and legal requirements. This distinction is important for both legal compliance and scientific integrity. Research peptides allow scientists to conduct controlled experiments and generate data that may eventually lead to approved therapeutic applications, but the peptides themselves remain strictly research tools.

Specifications, Handling, and Storage

Before incorporating research peptides from Pure Tested Peptides into a new study, teams typically review specifications such as the amount per vial, nominal purity percentage, and any notes on recommended storage conditions. These details are important because they determine how stock solutions are prepared, how frequently they should be remade, and what type of containers are appropriate for short-term and long-term storage. Many laboratories prefer to log each vial into an inventory system as soon as it arrives. A typical workflow might include assigning an internal inventory number, scanning the barcode on the shipping label, and recording the lot number from the vial label. Doing this at the receiving bench ensures that no vial is ever used without a clear record of its origin. It also makes it easier to rotate stock so that older vials are used first while newer vials remain in deep storage. Storage practices vary between institutions, but most research teams using research peptides from Pure Tested Peptides rely on designated refrigerators or freezers that are reserved for high-value reagents. Temperature logs, access control, and regular maintenance of refrigeration equipment are simple steps that help protect peptide integrity. Clear “research use only” notation further reinforces that the materials are not intended for any type of administration or diagnostic procedure. Supplemental images showcasing multiple vials together are often used in presentations, internal…
