Purple Peptides protocols

The eight stacks, as listed

Each one in turn

The retail price that changes when you turn the page

This is the finding on this vendor that we did not go looking for. Almost every kit states one retail price on its own product page and a different one on the store listing, and on three of them the two numbers cannot both be true.

The Phoenix 30 day kit carries a $236 retail value on its product page, where the store says the retail was $297 and advertises a 34 percent saving. The Wolverine 30 day kit says $158 on the page and $297 in the store. The Wolverine 60 day kit then says $305 in the store, which is less than the store’s own $297 figure for a kit holding half as much. The Elevate is the only kit whose two pages agree, at $662, and the Spartan and the Foundation and the Longevity only ever state one figure each, so there is nothing to cross-check those against.

We are not saying the discount is fake, because we cannot see the vendor’s margin and we are not entitled to guess at it. We are saying that a saving is only meaningful against a price the seller will honour, and that a retail figure printed on two pages of the same website in two different amounts is a marketing number rather than a list price. Where a kit publishes its contents we have priced the components that are sold separately, so a reader can do the arithmetic the vendor has not done.

A protocol that ships without a protocol

The vendor sells kits under the names of a 30 day protocol and a 60 day protocol. It also answers, in its own FAQ, the question of whether the products come with instructions. The answer is:

Products from Purple Peptides do not include usage instructions, as they are strictly for in vitro research and prohibited by law for human or animal use.

So the words 30 day and 60 day describe how many vials are in the box, not a documented schedule, and the vendor says so itself. We publish no schedules either, for a different reason: what any individual should take is a clinician decision, and these compounds are not approved for human use anywhere. The point here is narrower and worth being exact about. The word protocol implies instructions. There are none, and the product name promises something the vendor is careful not to deliver.

The naming problem

Phoenix, Spartan, Wolverine, Elevate, Foundation, Longevity, Purple Neuro. Not one of those words tells a buyer what is in the vial. The Wolverine page is built on what it calls the Wolverine Principle, on being forged in resilience, and on the line that wolverines do not recover, they adapt. That is motivational copy standing exactly where a component list belongs, and a stack named after an animal is not documentation.

The product labels have the same problem at a smaller scale. Nearly everything in the catalogue carries the tag Recovery Compound, including Melanotan 2, which is a tanning agent, and NAD+, KPV and DSIP. A category label that fits a tanning peptide and a metabolic peptide describes neither of them. The catalogue also lists a product called Tirz at $99. Tirzepatide is a licensed medicine in a growing list of countries, and a research grade version of a licensed medicine is not the licensed medicine, which is the argument our tirzepatide guide sets out at length.

Where the vendor is more candid than most

Worth saying clearly, because it cuts against the rest of this page. The GLOW page grades the evidence for its own three compounds. It calls GHK-Cu strong human data, BPC-157 promising animal data with limited human clinical trials so far, and TB-500 preclinical and mechanistic with human data still developing. Those grades sit close to ours, though ours are a step stricter: we rate GHK-Cu Tier C, because its human evidence is topical rather than injected, and both BPC-157 and TB-500 Tier D, which is preclinical only. A vendor that grades its own stack in roughly the right order and stops short of claiming a licence is rarer than it should be.

Documentation gaps you can see for yourself

Two things are visible on the vendor pages without any testing at all, and both sit under the heading of that verification standard.

The second gap is the purity number, and we set it out on our blends page: a target of 99 percent or better in the standard, 99 percent certified on GLOW, and 100 percent purity verified on Wolverine. The store listing also shows at least two products priced at zero dollars. None of that is proof of anything wrong in a vial. All of it is a reason to read the listing rather than the brand.

Two vials, three compounds, one certificate

The two kits that do publish their contents are built the same way. Each pairs a two component blend with MOTS-c, so both vials in each kit are multi-compound products, and that is the hardest case a certificate of analysis has to resolve. A single purity figure covering a mixture cannot tell you the proportion of the components inside it. Ask whether each component is identified separately. If the answer is that one figure covers the whole blend, you have learned exactly what the document does not say.

Who can buy, and who cannot

These are US products, sold from a US facility, priced in dollars, and the kits ship free in the domestic market. Readers in the European Union and the UK cannot use the links on this page, and we would rather say that here than have you discover it at checkout. Our blends page sets out the shipping position in more detail.

What to ask before you buy a kit

• What is in the box, in milligrams, in writing. Six of these eight stacks do not say. Ask first, and keep the answer.
• A certificate per vial, carrying the batch code on your vial. A kit contains more than one vial, so it should come with more than one document.
• Whether each component is identified separately, or one figure covers the blend. Those are different documents and one of them cannot answer the question.
• Endotoxin results for anything presented as suitable for injection. None of this is approved for human use in any case.
• What in the kit is not a peptide. Bacteriostatic water is included with several kits and should not be counted as an active compound.
