Research use only
All research products on this site, including all peptides, are sold strictly for laboratory and research use only, not for human or animal consumption, diagnostic, or therapeutic use. Our tallow skincare products are topical cosmetics. You must be 21 or older to enter.

A storefront, a phone number and 25 published certificates.
We sell research compounds from a retail counter at 967 Lawnsdale Rd, Unit 2, Medford, Oregon. Walk in during the hours posted below, call and get the store rather than a ticket queue, or read the measured purity of every batch we have published. The rating, the certificates and the purity figures all link back to their source.
What we can show you
The certificate figures are read from our live catalog every hour. The purity number moves when a new batch comes back from the lab. The newest certificate we have published was reported on 08/11/2026.

“First off, the customer service is amazing! They answer any question no matter how silly I think it is. They're very knowledgeable about all their products and set you up so you leave with confidence.”
We do not publish a staff directory. Instead we publish our faces, our street address, our phone number and certificates signed by an outside lab, all on one page. That is what we can stand behind.

What customers say about the service
5.0from 81 Google reviews“Optimum ReGen Peptides has exceeded all our expectations for research supply. Knowledgeable, experienced representatives, incredible shipping, and attention to detail make this our first stop. Extremely professional, and genuinely good people.”
“I did a lot of research before purchasing, and I'm glad I did. They are the real deal. I reviewed their COAs and appreciated the transparency. Knowing they back their products with testing gave me confidence in the quality.”
“I absolutely love Optimum ReGen Peptides. Amazing customer service, quick shipping, and high-quality USA-compounded products with COAs to match.”
“I don't leave reviews often, but these guys absolutely earned one. From my first interaction I was treated like a longtime customer instead of just another sale. They went out of their way, and the communication was outstanding.”
“It's tough finding good quality with direct, great service. The owner, Ian, called me personally and walked me through the process. It's been a great experience, and 2-day shipping is unheard of.”
“An outstanding experience with this local peptide supplier. Their prices are hands down the best I've found, but what really sets them apart is the customer service: friendly, knowledgeable, and never making you feel rushed.”
The rating and the count come straight from Google. We choose which reviews to feature and we trim them for length. The ones we show are about buying from us, not about what a compound did for anyone, because these are research compounds and we do not publish outcome claims. Read them all on Google, unfiltered and in full.
Tested, then published
Every peptide we sell is tested the same way.
Tested by an outside lab
Batches go to Freedom Diagnostics, an independent analytical laboratory, for HPLC purity and LC-MS identity.
Published with the accession number
Each certificate goes up with its accession number, hosted by the lab rather than by us, so the document you read is the one the lab signed. We have not published one for every compound yet.
The rules we hold ourselves to
A claim nobody can check is worth nothing.
We show a purity figure only where a certificate reports one, on the product that certificate covers. No product borrows another product's result.
We do not publish claims about what a compound does in a person. No benefits, no dosing, no protocols, no before and after. These are research compounds, supplied for laboratory use only.
We feature reviews about service, not outcomes. Anything that reads as a health outcome is filtered out in code before it renders, even when it is a five-star review.
We publish the low numbers too. The lowest purity we currently show is 96.397%, and it sits on the lab testing page next to the higher ones, because a company that publishes only its best numbers is not publishing anything.
25 certificates, covering 24 products
This is the most recent published batch for each product, tested by Freedom Diagnostics. The purity shown is what the lab measured on that batch, not a target we set. If a product is not on this list, its page will not show a purity figure. Published certificates cover 24 of the 49 products we currently list. The rest are peptides we have not published yet, plus the tallow skincare, bacteriostatic water and other items no purity assay describes.

The research compounds we sell are for laboratory use only. They are not for human or veterinary use. The tallow skincare is not one of them: it is an ordinary topical cosmetic and is sold as one. Nothing on this page is medical advice.
