Purple Peptides blends
Four blends listed from $89.00 to $169.00. Two of them tell you what is in the vial and two do not, which is most of the review in one line.
The short answer
Two of these four blends let you see what you are buying and two do not. GLOW names three compounds and a 70 mg total. BPC-157 + TB-500 and CJC-1295 + Ipamorelin name their components and publish no quantities. KLOW is sold on the name alone. None of the four has ever been tested as a blend, because a blend is a product category and not a molecule, and no trial has been run on one.
The four blends, as listed
| Blend | Contents named | Split published | Price |
|---|---|---|---|
| BPC-157 + TB-500 | BPC-157, TB-500 | No | $99.00 |
| CJC-1295 + Ipamorelin | CJC-1295, Ipamorelin | No | $89.00 |
| GLOW | BPC-157, GHK-Cu, TB-500 | Yes | $169.00 |
| KLOW | Not stated | No | $159.00 |
Each one in turn
BPC-157 + TB-500
Named contents. BPC-157 Tier D, TB-500 Tier D
Component split. Not published. The listing names both compounds and gives no quantities.
- Single vial: $99.00
Both components came off the FDA 503A Category 2 bulk list in April 2026. That is a compounding classification change, not an approval, and it changed nothing about their status for human use. The component to be careful with is TB-500: the human trials its sellers cite were run on full length thymosin beta-4, which is a different molecule from this fragment.

CJC-1295 + Ipamorelin
Named contents. CJC-1295 Tier C, Ipamorelin Tier B
Component split. Not published. The listing names both compounds and gives no quantities, and unlike the kits this one is not described as including bacteriostatic water.
- Single vial: $89.00
This is the one blend here whose two components both stayed on the FDA 503A Category 2 list in April 2026, where the grounds cited included cardiac adverse event signals. The April 2026 delisting news that other sellers quote as blanket reassurance did not cover these two compounds, and a page citing it for this pair has not checked which compounds it covered.

GLOW
Named contents. BPC-157 Tier D, GHK-Cu Tier C, TB-500 Tier D
Component split. Partly published. Three named compounds and a 70 mg total are stated. The split of that 70 mg between them is not.
- 70 mg blend: $169.00
The clearest of the four, and the vendor is unusually candid about it. Its own page grades the three compounds separately: strong human data for GHK-Cu, promising animal data with limited human trials for BPC-157, and preclinical research for TB-500. That is a step more generous than our scale, which puts GHK-Cu at Tier C because its human evidence is topical rather than injected, and rates both BPC-157 and TB-500 Tier D, where the evidence is preclinical. The chips above are ours. A blend cannot rise above the weakest compound in it.

KLOW
Named contents. Not published.
Component split. Not published. The listing gives a name and a price, and no component list at all.
- Single vial: $159.00
Sold on the name alone. KLOW is widely used elsewhere for a four component build of BPC-157, GHK-Cu, TB-500 and KPV, and we describe that build in our blends review, but we cannot confirm this vial contains it because the vendor does not say. Ask in writing before buying a product whose contents are not on the page.

Why a blend is harder to check than a single vial
Verification difficulty scales with the number of components. A single compound vial can be identified by mass spectrometry and its purity measured by HPLC, and both figures either match the label or they do not. A blend turns one question into several: what is in the vial, in what proportion, and is that purity figure a figure for each component or for the mixture. Those are different documents, and vendors rarely say which one they are handing you. We set the argument out in full in our review of peptide blends, and it applies to every product on this page.
None of the four has been through a controlled human trial as a blend. The individual components have their own records, which is why we link to each component guide above rather than treating a blend as a new thing with its own evidence. A blend cannot be better evidenced than the weakest compound in it, and it is usually worse, because the sum of two unapproved compounds is not an approved one.
What the vendor publishes
Purple Peptides sets out a three part standard: a purity target of 99 percent or better verified by HPLC and mass spectrometry, testing at manufacture followed by an independent third party, and release only when identity, testing and documentation align. There is a certificate of analysis page, and the brand states that every batch is tested. Those are the right things to claim, and a claim of that kind is the sort you can hold a vendor to, because a purity figure is only as good as the document behind it.
The published numbers do not agree with each other. The standard stated across the site sets a target of 99 percent or better. The GLOW page says 99 percent certified. The Wolverine page says 100 percent purity verified. A target of 99 or better and a claim of 100 are not the same statement, and the stronger claim is the one carrying the weaker qualification.
Where these ship, and who cannot use them
Purple Peptides is a United States vendor. It states that orders ship from its US facility, that prices are in dollars, and that domestic delivery is typically three to five business days. Readers in the European Union, the UK and most of the rest of the world cannot use the links on this page, and we would rather say so than have you find out at checkout. EU readers should read our other blend comparison instead.
What to ask before you buy
- The split in milligrams, in writing. For GLOW, ask what proportion of that 70 mg is GHK-Cu. A refusal or a vague answer is information.
- Whether the certificate identifies each component separately, or reports one combined purity figure. Those are very different documents.
- Whether the batch code on the certificate matches the vial in your hand. A batch matched report is worth more than a brochure.
- The measured content, not just the purity. Purity is the proportion of the powder that is the target molecule. It does not tell you how many milligrams are in the vial, and we have published a case of a 50 mg label holding 44.05 mg.
- Endotoxin testing for anything presented as injectable grade.
The general method is in our guide to reading a certificate of analysis, which sets out the checks that apply to every compound. All of them get harder as the component count goes up, which is the whole problem with this category.

Common questions
Are these blends cheaper than buying the components separately?
On the listed prices, not much. BPC-157 is listed at $39.00 and TB-500 at $69.00, so $99.00 for the pair is close to the sum of the parts, and in exchange you give up knowing the split.
Does a 99 percent purity figure mean the blend is what the label says?
No. Purity is the proportion of the powder that is peptide. It is not proof of which peptides are present or in what amounts. For a three component blend the useful number is the measured content of each component, and that is the number almost nobody publishes.
Is it legal to buy these?
The vendor sells them as laboratory research material and states they are not for human or animal use. That framing is what keeps the sale itself lawful in the United States. Buying one does not make a research chemical an approved medicine, and using one is a separate question with a different answer in every country.
