Blends

8 of these 9 vials have never been tested as a vial

That is the single most useful fact about this category, so it goes first. A blend is sold on the strength of its ingredients, and the ingredients were studied one at a time, separately, usually in animals. Nobody ran the combination. Nobody checked whether the components are stable together in one vial, whether their effects add up or overlap, or what ratio a person should want. The product exists; the study of the product does not.

Below are the 9 blends in this database, drawing on 14 distinct compounds. Each card shows what is in the vial, what share of the powder each ingredient is where a label mass can be sourced, what the component evidence actually supports, and the specific problem that particular combination creates. Exactly 1 of them carries a tested badge, and it is worth seeing why: multi-ester testosterone blends.

The 9 blends, and what is in them

Amounts are the milligram figures printed on common labels, never doses. The share beside each one is calculated from those figures, so it shows what the vial is mostly made of rather than what the name emphasises.

KLOW

4 components · 80 mg on the label

Never tested as a combination
  • GHK-Cu50 mg · 63% of the mass

    A copper tripeptide with small topical skin studies. Here it is most of the powder, and a repeated copper load.

  • KPV10 mg · 13% of the mass

    The alpha-MSH tripeptide, given alone in mouse colitis models where it reduced inflammatory markers.

  • BPC-15710 mg · 13% of the mass

    Animal tendon and gut repair data, plus one retrospective series of twelve knee patients.

  • TB-50010 mg · 13% of the mass

    Sold as thymosin beta 4, identified in the lab as a seven amino acid fragment of it.

What is known
Each of the four has a literature of its own, and all of it is single agent: topical skin work for GHK-Cu, mouse colitis for KPV, animal repair models for BPC-157, and actin-binding work for the fragment inside TB-500.
The catch
GHK-Cu is the majority of the vial by mass, so this is mostly a copper peptide product whichever component you came for, and the ratio is fixed, so lowering the copper means lowering the other three with it.

GLOW

3 components · 70 mg on the label

Never tested as a combination
  • GHK-Cu50 mg · 71% of the mass

    The skin claim in the product. Its human evidence is topical and cosmetic, not injected.

  • BPC-15710 mg · 14% of the mass

    Animal repair data and one small uncontrolled human series.

  • TB-50010 mg · 14% of the mass

    The actin-binding fragment, with no human trial of its own.

What is known
GHK-Cu has the better documented component record for skin, from small topical studies measuring appearance. The two healing peptides bring animal data for tissue repair.
The catch
It is KLOW with the KPV removed and the same copper-dominant mass, so a product bought for skin delivers most of its milligrams as a compound whose skin evidence was gathered by putting it on skin rather than under it.

Wolverine

2 components · 20 mg on the label

Never tested as a combination
  • BPC-15710 mg · 50% of the mass

    The larger half of the claim. A 2025 systematic review found 36 studies, 35 of them preclinical.

  • TB-50010 mg · 50% of the mass

    Marketed as thymosin beta 4. Mass spectrometry on the product identified Ac-LKKTETQ, seven of its 43 amino acids.

What is known
Two separate preclinical repair literatures, one of them substantial in animals. There are registered single agent trials for each component and none for the pair.
The catch
The thymosin beta 4 research that sells this vial is research on a molecule the vial does not contain, and with an even split there is no way to keep the component you believe in while dropping the one you do not.
Blend calculator
CJC-1295 with ipamorelin

2 components · 10 mg on the label

Never tested as a combination
  • CJC-12955 mg · 50% of the mass

    The GHRH analogue half, which raises the size of a growth hormone pulse.

  • Ipamorelin5 mg · 50% of the mass

    The ghrelin-receptor half, selected by sellers for releasing GH with less effect on cortisol and prolactin than older GHRPs.

What is known
Both halves have human pharmacokinetic work showing each raises growth hormone on its own, and they act at two different receptors, which is the mechanistic reason the pairing is offered at all.
The catch
Most material labelled CJC-1295 without DAC is mod GRF 1-29, so the name on the vial may not be the molecule inside it, and because both halves push the same growth hormone axis, any change in IGF-1 belongs to the pair rather than to either component. Vials are also sold at ten and ten, so read the label rather than assuming the ratio here.

Tesamorelin with ipamorelin

2 components · no consistent label mass

Never tested as a combination
  • Tesamorelinamount not sourced

    The one growth hormone secretagogue in this group with an approval and phase 3 visceral fat data behind it.

  • Ipamorelinamount not sourced

    A ghrelin-receptor secretagogue with short human pharmacokinetic studies and no outcome trial.

What is known
Tesamorelin carries the strongest single agent record of anything on this page apart from testosterone: an approval, phase 3 trials and a defined daily dose for reducing visceral fat in HIV lipodystrophy.
The catch
That evidence belongs to tesamorelin given alone at its own dose, so a compounder's ratio puts you outside the only data that made it worth using. No vial size is canonical, though 5 mg plus 5 mg and 10 mg plus 3 mg are both common; the compound page works the arithmetic for those. The sharp version of the problem is that on a 5 plus 5 vial you cannot reach the 2 mg of tesamorelin that produced the approved result without also taking 2 mg of ipamorelin, roughly seven to ten times the amount anyone uses on purpose.

NAD+ with B-complex

2 components · no consistent label mass

Never tested as a combination
  • NAD+amount not sourced

    The headline ingredient, with human trials showing blood NAD rises after dosing and much thinner evidence for what that changes.

  • Vitamin B12amount not sourced

    The one ingredient here with a blood test that says whether you need it, and decades of evidence for correcting a deficiency.

What is known
B12 replacement in a deficient person is settled medicine, measurable before and after. NAD precursors have human trials that raise blood NAD, with much weaker evidence that the rise produces the energy and aging benefits used to sell it.
The catch
Two ingredients with opposite evidence quality arrive in one syringe, so the half that genuinely works for deficient people is what you feel and the half being marketed takes the credit. No formulation is canonical, though 250 to 500 mg of NAD+ with a 1,000 mcg B12 add-on is the common drip; the compound page works that split, and B12 is about two tenths of one percent of it by mass. The B6 in an injectable B-complex is pyridoxine, the vitamer behind the reported neuropathy cases, which is worth knowing before it is added to anything.
Semax with selank

2 components · no consistent label mass

Never tested as a combination
  • Semaxamount not sourced

    An ACTH fragment used clinically in Russia for stroke and cognitive indications, studied almost entirely in Russian language literature.

  • Selankamount not sourced

    A tuftsin analogue used in Russia for anxiety, with small domestic trials and no Western replication.

What is known
Both are registered medicines in Russia with domestic clinical use, semax for stroke and cognition and selank for anxiety, which is more than most peptides in this database can claim.
The catch
One is sold as activating and the other as calming, so the blend puts two opposing intents in one draw at a ratio the seller chose and you cannot adjust. Vial sizes are inconsistent across sellers, so the balance between them is not knowable from the outside.
Sermorelin with a GHRP

2 components · no consistent label mass

Never tested as a combination
  • Sermorelinamount not sourced

    The GHRH fragment that was an approved product for growth hormone testing and pediatric use before it was withdrawn commercially.

  • GHRP-2 or GHRP-6amount not sourced

    The ghrelin-receptor half, usually GHRP-2, sometimes GHRP-6, which has the stronger appetite effect of the two.

What is known
Sermorelin was an approved medicine and GHRP-2 has human evidence for producing a growth hormone pulse. Combining a GHRH analogue with a ghrelin-receptor agonist is the oldest version of the two-receptor rationale in this category.
The catch
Which GHRP you got changes the experience, because these agents raise appetite, cortisol and prolactin to different degrees, and a fixed blend gives you no way to keep the sermorelin while backing off the GHRP when that shows up. Sellers do not publish consistent vial sizes for either half.

Multi-ester testosterone blends

4 components · 250 mg on the label

Tested as a combination
What is known
The exception on this page. The four-ester preparation is a licensed medicine in the United Kingdom and many other countries, so the mixture itself was evaluated rather than assembled, and the hormone it delivers carries the largest safety trial in this database.
The catch
Every ester cleaves to the same testosterone, so the label milligrams are ester mass rather than hormone, and four release rates mean a blood level depends on which esters were still releasing when the blood was drawn. A single ester on a weekly or split schedule answers the same question and can be read.

What a blend costs you, in 4 parts

Convenience is the honest argument for a blend: one vial, one draw, one mixing step. These are the things you gave up for it, and none of them are visible at the moment of purchase.

  1. 01

    You cannot titrate one component

    The ratio was fixed by whoever filled the vial. Every adjustment you make to the draw moves all of the ingredients at once, in the proportions somebody else chose, so the only dose decision left to you is how much of their ratio to take.

  2. 02

    You cannot stop one when a side effect appears

    A reaction to one ingredient ends the whole vial, because there is no way to remove a component from a solution. With separate vials the same reaction costs you one compound and tells you which one it was.

  3. 03

    You cannot attribute a benefit or a harm

    If something improves, the blend gets the credit and you learn nothing you can carry to the next decision. If a marker moves the wrong way, you cannot say which ingredient moved it, which is the piece of information that would have been worth the money.

  4. 04

    The heaviest component dominates the vial

    Milligrams are not evenly divided. In several of these the ingredient with the largest label mass is not the one in the marketing, so most of what you inject is whatever the filler weighted the vial toward, whether or not it is the reason you bought it.

Doing the arithmetic on a blend

A single concentration figure is meaningless for a multi-compound vial, because each ingredient is present at a different amount and therefore arrives at a different concentration in the same millilitre. Blend mode in the calculator takes the component amounts printed on the label, the bacteriostatic water you added and the draw you intend, and returns what every component delivers in that one draw, separately. It is arithmetic, never a dose: every number that produces a result comes from you.

6 of the 9 blends here have their label amounts stored as a calculator preset, so the component fields are filled in for you: KLOW, GLOW, Wolverine, CJC-1295 with ipamorelin, Tesamorelin with ipamorelin, Sermorelin with a GHRP. For the rest, open blend mode and type the amounts from your own label.

Questions people ask about this

Has anyone tested these blends as blends?
Almost none of them. Of the 9 multi-compound vials catalogued here, 1 was evaluated as a product rather than assembled from its parts, and that one is a licensed multi-ester testosterone preparation rather than a peptide blend. For the other 8, every claim made for the combination is borrowed from single agent studies of the ingredients.
If each ingredient has evidence, does the blend have evidence?
No. Evidence for A and evidence for B is not evidence for A plus B. It says nothing about whether the two are stable in one vial, whether their effects add up, cancel out or overlap, what ratio would be right, or what happens to the side effect profile when both arrive at once. Those are the questions a combination study exists to answer, and for these products it was never run.
Why does the mass share matter?
Because it tells you what you are mostly injecting. A vial can carry four named ingredients and still be, by weight, one ingredient with three garnishes. The share column on each card below is calculated from the label amounts, so you can see which component the vial is actually made of before you read what it is sold for.
How do I work out what one draw delivers from a blend?
Use blend mode in the reconstitution calculator. It takes each component's label amount, the water you added and the draw you intend, and returns the amount of every ingredient in that draw separately, because a single concentration figure is meaningless when the vial holds several compounds at different amounts.
Why are some vial amounts missing here?
Because sellers do not agree on them. 4 of the 9 have no vial size consistent enough to quote, so the amount is left blank rather than invented. A made-up milligram figure would produce a made-up mass share, and the share is the part of this page worth reading.
