Peptide Stacks, Blends and Starter Kits

Three distinct kinds of product sit under a single heading. What turns up in the box differs each time, and so does the paperwork that travels with it.

About Peptide Stacks, Blends and Starter Kits

What is a peptide blend?

A blend is one vial holding several compounds that were combined before being freeze-dried. A single vial, a single label naming everything inside, a single certificate of analysis covering the mixture as one.

Since the components are already combined, there is no separating a blend later. The vial is reconstituted once and every component within it enters solution at the same time, in whatever ratio the label records. The blends in this range are GLOW, KLOW and the three cagrilintide blends.

What is a peptide stack?

A stack is a set of separate vials sent together in one box. None of it is combined. Every vial brings its own label, its own batch number and its own certificate, and each is reconstituted separately.

In practice this means a stack can be pulled apart where a blend cannot. Should you want to swap one component, or draw on the vials at different times, a stack permits it. Wolverine, Recovery, Metabolic and the others are stacks.

What is a starter kit?

A kit pairs one compound with the items needed to prepare it: bacteriostatic water, insulin syringes and alcohol swabs, or pen needles when the kit is built around a pen. The vial within matches the one sold separately; the kit exists so a first purchase can be one order rather than three.

Why buy a blend instead of the individual compounds?

Three reasons, every one of them practical rather than pharmacological.

  • One vial instead of several. A single reconstitution, a single container to store, a single thing to keep track of.
  • Less glass, less packing, less postage. This is why a blend is priced below the sum of its parts; the saving lies in the logistics rather than in a discount on the compounds.
  • A fixed ratio. The proportions are locked in when the blend is made, so each millilitre you draw holds the same mix.

And the case for buying separately instead: control. Individual vials can be reconstituted to different concentrations, drawn on at different times, or bought one by one. Every component of every blend and stack on this shelf is sold on its own too, and each product page sets out what its contents cost separately next to the price of the box.

Why buy a stack instead of the individual compounds?

The vials are identical vials. A stack is a packaging and pricing choice: the same material, in one box, cheaper than buying each one on its own. Should you want just two of the three components, buy those two; nothing is lost.

What does the milligram figure on a blend label mean?

It is the total across every component in the vial, rather than the strength of any single one. An 80mg four-component blend carries 80mg of compound overall, split across four things. A 50mg three-component blend is not weaker; it simply holds less in total, split differently.

This is the figure most often misread on any label we print. The product page for each blend sets out the breakdown, and how to read a vial label runs through every line on it.

Which blend do I have?

The label names every component. If what you hold is one of ours, the compound line will name them; where the components go unnamed on the label, it is not one of ours and we cannot say what is inside it.

The K in KLOW stands for the KPV. That alone is what separates the two.

How do I store a blend or a stack?

Storage, by what is in the box
StateBlend (one vial)Stack (several vials)
Sealed, as powderCool, dry and away from direct light. A freezer works for holding it long term.
Once reconstitutedRefrigerated, upright, not frozenEach vial separately, under the same conditions
LightKept out of direct light at all times
Shelf lifeNot published; the label and that batch's certificate are the authority

A stack reconstituted all in one go leaves several open solutions going at once. Where you are working with a single component only, there is nothing to be gained by making up the rest.

Is there any research on these combinations?

No published study examines any of these combinations as a combination. Every component has a published record of its own, linked from its own product page, and none of those papers sets out what occurs when the components are supplied together.

So nothing on this shelf rests on research into the combination itself. Anyone claiming what a given blend contributes is not taking it from a study.

How are these priced?

From the contents. A stack comes to the sum of its vials at a discount; a blend is discounted further still for being one vial in place of several. Every product page displays what the components cost separately next to the price of the box, so the saving can be seen rather than merely claimed.

Research use only. Incrementin provides compounds for use in laboratory research. None of what we sell is a licensed medicine, we do not operate as a pharmacy, and we put out no dosage, protocol or administration guidance. Not for use in humans or animals, and not for use in food.

Stacks, Blends & Kits questions

What is the difference between a stack and a blend?

The number of vials that arrive. A stack is a set of separate vials, each labelled and traceable to its own batch, and it can be pulled apart. A blend is one vial whose components were combined before freeze-drying, under a single certificate, and it cannot be separated.

Why would I buy a blend instead of the separate compounds?

A single vial to reconstitute and store rather than several, a fixed ratio in every millilitre, and a lower price since it is less glass, packing and postage. Buy separately where you want to set the concentrations independently.

Does an 80mg blend mean 80mg of one compound?

No. That figure sums every component in the vial. You will find the breakdown on the product page.

How do I know which blend I have?

The label names every component. Each of our blends names its contents both on the label and on its product page.

How should I store a blend?

Sealed as powder: cool, dry and away from direct light, with a freezer fine for long holding. Once reconstituted: refrigerated, upright and not frozen.

What comes in a starter kit?

The vial, bacteriostatic water, syringes and alcohol swabs, or pen needles when the kit is built around a pen. The vial itself matches the one sold on its own.

Is there research on the combinations?

No published study examines these combinations as combinations. Each ingredient keeps its own record, linked from its own page.
