Education
How peptides are made, tested and delivered — and answers to the questions we hear most from clinicians and first-time buyers.
What a peptide is
A peptide is a short chain of amino acids — typically 2 to 50 — joined by peptide bonds. Many signaling molecules in the body are peptides, which is why synthetic peptides are studied so widely in metabolic, recovery, cognitive and longevity research. Each compound page on this site states the sequence class, the research area it is studied in, and the dosage forms we carry.
Dosage forms we carry
- Lyophilized Vials. Research-grade lyophilized peptide vials, sealed and third-party tested.
- Capsules. Ingestible peptide capsules — 60 count — built on our latest oral-delivery technology.
- Tablets. Precision-dosed peptide tablets — 60 count.
- Oral Sprays. Sublingual oral sprays for fast, needle-free ingestible delivery.
- Nasal Sprays. Metered nasal sprays — Pro-grade formulations in sealed, tested bottles.
- Topical Serums. Peptide-infused topical serums for skin.
How every lot is released
Identity by LC-MS, purity by RP-HPLC (≥99.0% for single peptides), and a safety panel covering endotoxin, sterility or microbial limits, and heavy metals — run by an independent laboratory before the lot ships. The full protocol and the certificate-of-analysis request form are on the Quality page.

Questions, Answered
Is every product really tested, or just a sample?
Every lot. Identity, purity and the safety panel are run on each lot by an independent laboratory before release, and the certificate of analysis is tied to the lot number on your label.
How do I get the certificate of analysis for what I bought?
Send the product name and lot number through the COA form on the Lab testing page or email info@biorepep.com. We send the matching certificate the same business day.
What does 'ingestible peptide' mean?
Capsules, tablets and oral sprays designed so the peptide survives digestion or bypasses it. Our tablets use SNAC, the absorption enhancer used in approved oral peptide medicines; our sprays are sublingual.
Can I put my own brand on BioRePep products?
Yes. Our white label program puts your logo on any product in the catalog, with certificates of analysis issued under your brand and low per-product minimums. See the White label page or send an inquiry.
Do you sell to clinics and distributors?
Yes. Clinics, practices and distributors get tiered volume pricing and lot-matched documentation. Use the contact form and include your business or license details.
What are the current offers?
Two promotions, one per order. Promotion A: enjoy 10% off your eligible purchase (applies to eligible products, before shipping and taxes). Promotion B: spend $200 in eligible regular-priced products (excluding shipping and taxes) and add our regularly $100 featured GHK-Cu + SNAP-8 serum for just $30 — limit one promotional serum per qualifying order. You choose one in the cart; selecting one turns the other off, and if the cart drops below $200 the serum offer is removed and the total updates. Discount codes can't be combined with these promotions.
How do I order?
Add products to your cart and check out securely with a card. Shipping is a flat $20 per order and taxes are calculated at checkout from your shipping address. In the cart you can choose one promotion: 10% off your eligible purchase, or — at $200 of eligible products — add our $100 featured serum for $30.
Where do you ship from, and how fast?
Orders ship from Houston, Texas. In-stock items leave within one business day; temperature-sensitive products ship with cold packs.
How should I store lyophilized vials?
Refrigerated at 2–8 °C and away from light. Once reconstituted, keep refrigerated and use within 30 days.
Are these products for human use?
BioRePep products have not been evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease. Consult a licensed healthcare professional before use.
