What is the CJC-1295 + Ipamorelin + GHRP-6 stack? It is a three-component peptide combination consisting of a CJC-1295-labelled GHRH analogue, the GH secretagogue ipamorelin, and GHRP-6. The name describes a combination used in research and commercial peptide markets rather than a universally standardized, clinically validated formulation.
Research-status note: CJC-1295, ipamorelin and GHRP-6 have been studied individually or in related growth-hormone research. That evidence should not be interpreted as clinical evidence for the exact three-component combination. Formulation, CJC-1295 variant, component ratio, purity and intended research endpoint can differ between products.

What Is the CJC-1295 + Ipamorelin + GHRP-6 Stack?
The CJC-1295 + Ipamorelin + GHRP-6 stack is a multi-component research combination built around peptides associated with growth-hormone-axis signalling. It should be described as a market/research combination, rather than as a standardized pharmaceutical formulation.
The most important nomenclature issue is CJC-1295. Commercial and research sources may use "CJC-1295" for either a DAC-containing long-acting analogue or a non-DAC form often described as Modified GRF(1-29). These are not interchangeable research materials.
!
Do not infer the CJC-1295 variant. A research page, product label or COA should identify whether the material is CJC-1295 with DAC, CJC-1295 without DAC/Modified GRF(1-29), and, where relevant, the chemical form such as free base or salt.
What's in the Stack?
Each component has its own molecular identity, research history and evidence profile. The three should not be treated as one molecule.
01
GHRH analogue
CJC-1295
CJC-1295 is described as a synthetic analogue related to growth-hormone-releasing hormone. Research literature includes human studies of the DAC-containing form showing prolonged stimulation of GH and IGF-1.
Key terminology: DAC and No DAC are distinct research variants.
02
GH secretagogue
Ipamorelin
Ipamorelin is a growth-hormone-releasing peptide investigated for its pharmacokinetic and pharmacodynamic effects in humans. Its research profile differs from that of CJC-1295.
GHRP-6 is a synthetic growth-hormone-releasing peptide that has been studied in human volunteers and in combination with GHRH during provocative GH testing research.
Key terminology: GHRP-6 is not the same compound as ipamorelin.
How the Shared Vial Concentration Works
In a true multi-component vial, all components occupy the same final liquid volume. The volume is shared; the component masses are not added together before calculating an individual concentration.
Figure 2. Mathematical model for a multi-component vial. The example uses equal 3 mg component masses solely to demonstrate the calculation.
Commonly Documented Formulations
There is no universally standardized CJC-1295 + Ipamorelin + GHRP-6 formulation. Commercial and research listings can differ in component ratios, total vial mass and, critically, the CJC-1295 variant.
Example formulation
3 mg / 3 mg / 3 mg
CJC-1295 + Ipamorelin + GHRP-6, 3 mg of each component.

CJC-1295 + Ipamorelin + GHRP-6 BAC Water & Concentration Reference
For a multi-component vial, every component shares the same final liquid volume, but each component retains its own mass. Therefore, each peptide must be calculated separately.
Component concentration (mg/mL) = component mass (mg) ÷ final volume (mL)
The table below uses the illustrative 3 mg + 3 mg + 3 mg formulation. It is a mathematical reference only and does not establish an appropriate research or human-use volume.

Important: Because all three components are present in the same vial, changing the final liquid volume changes the concentration of all three components simultaneously. The ratio between the components remains unchanged if no material is lost or added.
How BAC-Water Volume Changes Every Component's Concentration
If each component contains 3 mg, changing the final volume changes each component's concentration by the same mathematical factor.
Common calculation error: Do not calculate the concentration as (3 + 3 + 3) mg ÷ volume and then label that number as the concentration of each peptide. That produces the combined peptide mass per mL, not the individual concentration of each component.
Evidence for Each Component
Component evidenceCJC-1295
Human studies have evaluated CJC-1295 pharmacokinetics and pharmacodynamics. Published studies of the long-acting DAC form reported prolonged stimulation of GH and IGF-1 in healthy adults.
This does not establish equivalent evidence for every product sold under the CJC-1295 name, particularly where the DAC status is not specified.
Component evidenceIpamorelin
Human pharmacokinetic/pharmacodynamic research has examined ipamorelin in healthy volunteers and documented a GH response after administration.
These studies provide component-level information, not evidence that an exact CJC-1295 + ipamorelin + GHRP-6 blend is safe or effective.
Component evidenceGHRP-6
GHRP-6 has been evaluated in human research, including pharmacokinetic studies and studies examining GH responses.
GHRP-6 research should not be conflated with ipamorelin research. They are different peptides within the broader GHRP/GHS research family.
Evidence for CJC-1295, ipamorelin and GHRP-6 individually does not establish the efficacy or safety of the three together.
No controlled human study of the exact three-component CJC-1295 + ipamorelin + GHRP-6 formulation was identified in the literature reviewed for this page.
Has the Complete CJC-1295 + Ipamorelin + GHRP-6 Combination Been Clinically Studied?
!
Exact combination: evidence gap. The available evidence should not be presented as a clinical trial of the complete three-component blend. Human research exists for individual components and for related GHRH + GHRP-6 experimental combinations, but those are different interventions.
Importantly, human studies have shown that GHRH and GHRP-6 can produce strong GH responses when administered together. That finding is useful for understanding the biology of GHRH/GHRP signalling, but it does not prove that replacing the GHRH component with a particular CJC-1295 variant and adding ipamorelin creates a clinically validated three-component intervention.
Related combination research
GHRH + GHRP-6
Multiple human studies have investigated GHRH together with GHRP-6, including provocative testing for GH reserve.
This supports a mechanistic research rationale for studying complementary GHRH/GHRP pathways.
Not equivalent
Three-component blend
GHRH + GHRP-6 research is not equivalent to a study of CJC-1295 + ipamorelin + GHRP-6.
The exact molecules, ratios, pharmacokinetics, exposure profiles and safety characteristics must be evaluated independently.
CJC-1295: DAC vs No DAC
CJC-1295 terminology requires special attention because "CJC-1295" is not sufficient by itself to identify the research material.
DAC
CJC-1295 with DAC
The DAC-containing form is associated with albumin binding and a prolonged pharmacokinetic profile. Human studies have specifically evaluated this long-acting form.
Research distinction: prolonged exposure profile.No DAC
CJC-1295 without DAC
Market sources commonly use "CJC-1295 No DAC" to refer to Modified GRF(1-29). It should not automatically be treated as pharmacologically equivalent to CJC-1295 with DAC.
Research distinction: shorter-acting analogue terminology.Verification

Why Are These Compounds Combined in Research or Market Practice?
The conceptual rationale is that CJC-1295 is associated with GHRH signalling while ipamorelin and GHRP-6 belong to the broader growth-hormone secretagogue/GHRP research class. Related human research shows that GHRH and GHRP-6 can interact strongly at the level of GH secretion.
However, a mechanistic rationale is not the same as a validated combination therapy. Adding a third secretagogue changes the experimental system and creates additional variables that must be studied directly.
!
Research principle: complementary mechanisms can justify a hypothesis. They do not prove that the resulting combination produces better clinical outcomes or has an acceptable safety profile.
For laboratory mathematical reference, the concentration of each component is calculated from its own mass and the final liquid volume. The same volume is used for every component because they occupy the same vial.
Important mathematical distinction: 9 mg is the total mass of all three peptides in this illustrative vial. It is not the concentration of each individual peptide.
Need to Calculate Another Vial or BAC-Water Volume?
Use the BacScience Universal BAC Water Calculator for single-compound concentration calculations. For a multi-component vial, calculate each component separately using its own mass while applying the same final liquid volume.
Commercial listings can differ in total mass, component ratio and CJC-1295 terminology. A product name alone is insufficient to establish composition.
Combination evidence gap
Individual-component studies cannot be combined mathematically to create evidence for the complete three-component blend.
Route and formulation matter
Results from one formulation, route or experimental design should not automatically be transferred to another formulation.
Research material ≠ approved medicine
Research availability or commercial sale does not establish FDA approval, therapeutic efficacy or clinical safety.
Regulatory & Safety Considerations
CJC-1295 and ipamorelin have been specifically discussed by FDA in the context of bulk substances considered for compounding, including concerns related to characterization, peptide impurities, immunogenicity and, for CJC-1295, reported serious adverse reactions such as increased heart rate and systemic vasodilatory reactions.
FDA documentation has also identified safety concerns relating to ipamorelin acetate and noted limited information for certain injectable routes.

Do not interpret this page as a human-use protocol. BacScience research pages should distinguish mathematical concentration calculations from clinical dosing, treatment recommendations or administration instructions.
For competitive athletes, CJC-1295 and ipamorelin are listed among prohibited growth-hormone-releasing factors/secretagogues under the World Anti-Doping Agency prohibited-list framework. GHRP-6 is also included in that category.
Frequently Asked Questions
Is CJC-1295 + Ipamorelin + GHRP-6 a standardized formulation?
No. The combination appears in research and commercial contexts, but component ratios and the exact CJC-1295 variant can differ. A product should be evaluated from its actual label and lot documentation.
Does CJC-1295 + Ipamorelin + GHRP-6 have clinical evidence as a complete stack?
The individual components and related GHRH/GHRP combinations have research histories, but that evidence should not be presented as a controlled clinical trial of the exact three-component blend.
Does CJC-1295 with DAC mean the same thing as CJC-1295 without DAC?
No. DAC and No DAC refer to materially different research forms and should be identified separately. The long-acting DAC form has a substantially different pharmacokinetic profile from the shorter- acting No DAC/Modified GRF terminology used in many research listings.
If a vial contains 3 mg of each peptide, is the total concentration 9 mg/mL?
No. If the final volume is 3 mL, each peptide is 1 mg/mL. The combined mass is 9 mg, but the individual concentration of each component is calculated from that component's own mass.
What happens when the liquid volume is increased?
Increasing the final volume decreases the concentration of every component proportionally, assuming the component masses remain fixed.
Can the Universal BAC Water Calculator calculate this blend?
The universal calculator is primarily designed around single-compound concentration mathematics. A multi-component vial requires the same volume calculation to be performed independently for every component.
Does evidence for GHRH + GHRP-6 prove that this three-peptide stack works?
No. Related GHRH + GHRP-6 studies provide mechanistic context, but they do not establish the efficacy, safety or optimal formulation of CJC-1295 + Ipamorelin + GHRP-6.
