Integrative Peptides Review: Is It Legit? My Experience and What I Could Verify
I took two of their BPC-157 capsules for about four months, and my very first order went missing in the mail. Here's what the company actually sells, what its labels and policies say, which claims I could check, and which ones I couldn't.
We may earn a commission when you buy through our link. It doesn't change what I report here.
The short answer
Integrative Peptides is a real US company selling oral peptide and bioregulator supplements, with clear labels, card payments and a support team that replaced my lost order. Its headline quality claim is the part I couldn't confirm: it says every batch is third party tested, but it names no lab and publishes no certificates.
The verdict
Is Integrative Peptides legit?
Yes, as a company. It has operated since 2018, prints a US address on every label, answers email and text messages, and replaced my first order when the mail lost it. Whether its products are tested the way its homepage says is a separate question, and the public record doesn't answer it yet.
I sorted everything I checked into three piles. Green is what I could confirm myself from labels, policies, the brand's own store data or my own orders. Amber is what the company says but doesn't document publicly. Red is what's worth knowing before you order.
Verified
- A real company: “Integrative Peptides, LLC, Cheyenne, WY” on every label I checked, a public FAQ, return policy and support contacts.
- Clear Supplement Facts panels: amount per capsule, directions, storage and warnings.
- Official list prices in its own public store data, from $110 to $185 for most of its peptide products.
- My lost first order was replaced quickly, and later orders arrived normally.
Brand says, not documented
- “≥99% purity verified by third party testing” for each batch. No lab is named and no certificate is published.
- Its capped peptides are more absorbable by mouth. No human study has measured this for its products.
- A “GMP Certified” seal on labels, with no certifier named.
Know before you order
- You must confirm you're 21 or older and create an account before you see prices or buy.
- Refunds are rare. Returns get store credit, and the written policy doesn't cover lost parcels.
- Lookalike web stores use the brand name. Buy only at integrativepeptides.com.
- None of these peptides has solid human evidence yet.
How I checked
- Four months of my own orders and use
- Labels read from the brand's own product images
- 78 products and list prices from its public store data
- Policies from its FAQ, returns and promotion pages
- Evidence from PubMed and FDA reviewer documents
The website doesn't name a founder. It describes the company as started by a group of healthcare professionals, including physicians, and selling since 2018.
My take
A legitimate, consumer friendly brand with better labeling than most peptide sellers, and weaker proof of testing than its homepage suggests.
What I actually used
My four months with Integrative Peptides
I bought Integrative Peptides BPC-157 PURE because I'd been dealing with loose stools and stomach pain for a while. I took the delayed release version for about two months, then the immediate release version for about two more.
My symptoms eased a little over that stretch, and I first noticed it around day 60. It wasn't dramatic and it wasn't a cure. Later, proper GI testing found what was really going on, and treating that helped far more than anything I took.
I couldn't tell the two versions apart. The change I noticed landed right around the switch, so it doesn't favor either one.
Worth noting: one person's experience can't show whether a supplement works. My symptoms could have shifted for other reasons, which is exactly why I don't read my own result as proof.

Buying from them
What ordering is actually like
Integrative Peptides doesn't work like a normal online store. Product pages and prices stay hidden until you're signed in, so the first few steps happen before you see a single price.
- 1Confirm your ageA 21+ age check appears when you arrive.
- 2Create an accountName, email, birthday, username and password, or Google or Microsoft sign in.
- 3Pay by cardThe checkout footer shows Visa, Mastercard and American Express.
- 4ShippingUS orders usually ship the next business day and arrive in 2 to 5 business days. International takes 2 to 5 weeks.
Official policy
- Lost parcels: “We're not responsible for lost, stolen, or delayed packages once shipped. Refunds are not provided.”
- Cancellations: no refunds. An order that hasn't shipped may be stopped and turned into store credit.
- Returns: new, unopened products within 30 days, for store credit only. You pay return shipping unless they made the mistake.
- Shipping days: no overnight shipping on Fridays or Thursday afternoons, to keep temperature sensitive items out of weekend transit.
My experience
My first order never arrived. I contacted customer service, and they sent a replacement quickly. Every order after that arrived without a problem.
That's one customer's outcome, not a promise. The written policy says lost parcels aren't refunded, so keep your tracking number and watch it.

Testing and COAs
Is Integrative Peptides third party tested?
The company says so. I couldn't confirm it. Here's exactly what it claims, what I found, and what would settle it.
Brand claim · homepage
“≥99% Purity Verified by Third-Party Testing. Each batch is tested to confirm ≥99% purity.”
What I found
No lab is named anywhere public: not on the homepage, the FAQ, the labels or in any of its 78 product descriptions. The FAQ's own purity answer points you to customer service.
Brand claim · FAQ
“independent third-party testing for purity, heavy metals, microbials, and other contaminants.”
What I found
No certificate covering purity, heavy metals or contaminants is published for any product. Integrative Peptides also isn't listed on Finnrick, an independent peptide testing database.
The one certificate I've seen
BPC-157 PURE delayed release, lot 261201
- Dated
- 28 January 2026
- Assay
- .500 to .520 mcg per capsule as printed, against a specification of at least .500
- Microbes
- Seven organism panel, all within limits
- Signed by
- Company staff
- Outside lab
- None named
- Accreditation
- None stated
It's a real manufacturing record for one lot, which I requested through my contact at the company, so you may not get the same access. It isn't independent third party testing, and I haven't seen a certificate for any other product, including Thymogen Alpha-1.
What a genuine third party certificate shows
- An independent lab's name and address
- ISO/IEC 17025 accreditation
- A lot number that matches your bottle
- An identity test, such as mass spectrometry
- Purity or potency by HPLC
- Heavy metals and microbial results
Some oral BPC-157 brands already publish this. When I checked in September, ProHealth's lot certificate named an ISO/IEC 17025 accredited outside lab. If you want it from Integrative Peptides, email cs@integrativepeptides.com and ask for the certificate for your lot, plus the lab's name and accreditation.
Evidence check
What the science can and can't tell you
A trustworthy company doesn't make an ingredient proven. For almost everything in this catalog, the research is early, small, or done in animals and cells.
| Ingredient | In people | In animals or cells | Taken by mouth |
|---|---|---|---|
| BPC-157 | A few tiny uncontrolled pilots, none oral | Extensive | No human study has measured absorption |
| Thymogen (Glu-Trp) | Small Russian studies, given by injection or nasally. Western nasal spray cancer trials didn't beat placebo | Yes | No human oral data. The capped form in Thymogen Alpha-1 is unstudied |
| Immune Peptide A2 (Lys-Glu) | None found | Cells and mice, one research group | Unstudied |
| KPV | FDA reviewers found no human data | Animal and cell | Unstudied |
| TB4-Frag | FDA reviewers found no human data | Limited | Unstudied |
| Epitalon, Pinealon | One small study each, from one institute | Mostly one group | Unstudied |
| Organ bioregulators | Small, rarely repeated | Mostly one Russian institute | Unstudied |
Why “oral” matters
The brand says its peptides are acetylated and amidated, capped at both ends, which gives them “higher bioavailability and potency” than uncapped peptides. Capping can protect a peptide from some digestive enzymes, but it doesn't make it well absorbed. Even Rybelsus, an oral peptide drug engineered with an absorption enhancer, reaches only about 1% (NCBI, PMID 32479930). Capping a dipeptide may also weaken PepT1, the gut's main route for small peptides (NCBI, PMID 10848990). Nobody has measured absorption for these products.
Safety notes from the brand and the label
- Not for anyone pregnant, nursing, or under 18.
- The FAQ says some people report sleep changes, such as taking longer to fall asleep, on BPC-157 or Thymogen.
- If you take immunosuppressants, have had a transplant or live with an autoimmune condition, talk with your doctor before trying any immune focused product.
- No published human safety data exists for these capped peptides taken by mouth.

Labels and rules
Supplement or research product?
Integrative Peptides uses two kinds of language, and it helps to know which is which.
On the labels
“Supplement Facts” panels with the standard FDA statement, and 43 product descriptions that say “dietary supplement”.
On the website
The homepage describes “formulas intended for qualified research and educational use”, and CogniPep's description says “research and educational use only”.
“FDA registered”
From the FAQ. That's a facility registration. It isn't approval. No product here is FDA approved, and supplements never are.
“GMP Certified”
A seal on the labels. It describes manufacturing practice, not product effectiveness, and no certifier is named.
BPC-157 specifically
- Not FDA approved for any use.
- In July 2026 an FDA advisory committee voted 8 to 6 to recommend allowing it in pharmacy compounding, against the advice of FDA's own reviewers. FDA hasn't acted on that vote.
- The US Department of Defense's supplement safety program calls it an unapproved drug that isn't a dietary ingredient.
- It's on WADA's prohibited list at all times, so tested athletes should avoid it.

Before you paste a code from a coupon site
Coupon sites advertise 20% to 30% Integrative Peptides codes. The brand's affiliate codes are 10%. Two lookalike stores also use the name: integrativepeptidesstore.com, registered in March 2026 and advertising a 20% code, and integrativepeptidesusa.com, which offers a discount for paying in cryptocurrency. Neither is linked from the official site, and I couldn't find any connection to the brand. Buy only at integrativepeptides.com.

Fit
Who it may suit, and who should skip it
May suit you if
- You specifically want oral capsules rather than injections.
- You value clear labels, a US address and a support team you can reach.
- You're working with a clinician who knows these products.
- You accept that the evidence is early and results may be modest or absent.
Be cautious if
- You want an independent, published certificate before you buy.
- You're pregnant, nursing or under 18.
- You take immunosuppressants or have an autoimmune condition.
- You're a tested athlete. BPC-157 is prohibited in sport.
- You need the option of a refund.
Final verdict
I'd order from Integrative Peptides again for the buying experience: clear labels, card payments and a team that fixed my lost order. I'd also keep asking it for independent certificates, because that's the one thing its homepage promises and its public record doesn't show.
Quick answers
Integrative Peptides FAQ
Is Integrative Peptides legit?
Yes, as a company. It has sold oral peptide supplements since 2018, lists a US address on its labels, publishes its policies and answers customers. My lost order was replaced. What isn't publicly verified is its claim that every batch is third party tested.
Does Integrative Peptides publish COAs?
No. It says batches are third party tested but doesn't publish certificates or name a lab. I received one lot certificate for BPC-157 delayed release, and it names no outside laboratory. You can ask customer service for the certificate for your lot.
What did you personally use?
BPC-157 PURE delayed release for about two months, then immediate release for about two more. I haven't used Thymogen Alpha-1 or any other product in the catalog.
Does code SAMA work?
Use code SAMA for 10% off. Restrictions may apply. The brand's rules say coupons don't apply to bundles or Nature's Marvels products, and its seasonal sales can't be combined with other discounts.
Is Thymogen Alpha-1 the same as Thymosin Alpha-1?
No. Thymogen Alpha-1 is a capsule of two capped dipeptides. Thymosin Alpha-1 is a 28 amino acid peptide sold as a prescription drug in some countries, and Integrative Peptides doesn't sell it. Here's how they compare.
Does Integrative Peptides sell injectable peptides?
No. Its catalog is capsules, powders and oral sprays. Anything sold as an injectable under this name isn't from the official store.
Do the products need refrigeration?
The brand says no. Labels say to store them in a cool, dry place. I kept mine in the fridge anyway, as a personal preference.
Why can't I see prices?
Product pages and the store open only after you confirm you're 21 or older and sign in. The list prices in this review come from the brand's own public store data.
