What Our Customers Say
Real reviews from customers who trust our quality, design, and style.
I've tried peptides from three other suppliers. The difference with this batch was noticeable within two weeks. The COA actually matched what I was seeing, which doesn't always happen.
Marcus D.
Austin, TX
The order showed up in plain packaging exactly as described. No issues at the door, nothing flagged. Shipped faster than I expected and everything was sealed properly.
Tyler R.
Denver, CO
Emailed support about a question on storage temps before my order even arrived. Got a real answer in under two hours, not a copy-paste reply. That kind of thing matters.

The purity documentation came with the package. Ran it against a third-party lab I use and the numbers held up. That level of transparency is rare in this space.

I placed my second order without hesitation. Pricing is fair for what you're actually getting — research-grade material, not the gray-market stuff you find elsewhere.

Checkout was smooth, no sketchy redirects, confirmation came right away. Small thing but it tells you a lot about how a company operates on the backend.

Frequently asked questions
Everything you need to know before placing your order.
Are RCDbio peptides legal to buy in the USA?
Yes. Our products are research compounds sold for lab use only. We don't market them as drugs, supplements, or treatments, which is precisely what keeps them legal to purchase in the U.S. Every order ships with research-use-only labeling. We stay in our lane so you can stay in yours.
Are peptides the same as steroids?
No. Steroids are synthetic derivatives of cholesterol-backbone hormones operating via nuclear receptor pathways. Peptides are short-chain amino acid polymers with distinct receptor binding profiles. The structural, mechanistic, and regulatory classification of the two compound classes is entirely separate. Both appear in scientific literature spanning endocrinology and physiology research, which is the source of conflation.
What is a Certificate of Analysis (COA) and do your products have one?
A COA is a lab document that proves what's actually in the vial — purity percentage, compound identity, and the testing method used. We run every batch through HPLC, GC-MS, and NMR. It ships in the box with your order, not behind a contact form. Open it, check the lab name, look up the batch. Everything's there.
How do I know the purity is what you say it is?
Three independent tests, every batch. HPLC tells you how pure it is. Mass spec confirms it's actually the compound you ordered. NMR verifies the molecular structure. Your COA lists the lab name, test date, and batch number. Google the lab. Call them if you want. We've got nothing to hide.
What peptide categories do you carry?
Five categories: GH Secretagogues for growth hormone receptor pathway research, Longevity Peptides for cellular senescence studies, Metabolic Peptides for preclinical metabolic pathway research, Nootropic Peptides for in vitro neural receptor pathway studies, and Nasal Spray formulations for intranasal bioavailability research. All research use only, no exceptions.
How fast do you ship and how is it packaged?
Most orders leave our facility within 1 business day and land in 2-4 days. Packaging is plain with no brand name, no product labels, nothing on the outside that tells anyone what's inside. We place research-only labels on the product. Every shipment is fully insured. Something wrong when it arrives? Tell us. We make it right.
Can I use these peptides on myself or for personal wellness?
No, and we mean that. Everything on this site is for laboratory research only. Not for personal use, self-experimentation, or wellness routines. The FDA has not evaluated these compounds for clinical use, and we don't pretend otherwise. If you're purchasing, you're confirming you're a researcher working in an appropriate setting. That's not a checkbox — it's a real condition of sale.
What payment methods do you accept?
Crypto, credit and debit cards, and Apple Pay — processed through a PCI-compliant, 256-bit SSL checkout. Your payment data isn't stored on our end. And your personal details? Never sold, never shared, never rented — not to anyone, not for any reason.
