Frequently asked questions

Healthy Mango is a bilingual educational website about peptides and related research compounds. It publishes structured, cited, plainly written summaries of what the peer-reviewed literature, regulatory documentation, and a current practitioner reference report about each compound.

It is an information site, not a clinic, a pharmacy, a laboratory, or a peptide vendor. It does not diagnose, prescribe, or sell.

No. Healthy Mango is an educational information platform. It is not a healthcare provider, does not employ physicians in any provider capacity, and does not offer medical advice, diagnosis, or treatment.

Nothing on the site creates a physician-patient relationship. For any personal medical question, contact a licensed clinician in your jurisdiction.

Medical advice is personalised — it depends on knowing the reader's history, medications, allergies, and clinical context. An educational website cannot know those things and would be irresponsible to pretend otherwise.

Healthy Mango describes what published research reports at the population level. That is genuinely useful. It is also not a substitute for a clinician who knows you.

Healthy Mango is operated by HealthyMango™ LLC, a United States limited liability company. HealthyMango™ LLC is the party responsible for editorial content, for privacy practices under the Privacy Policy, and for legal notices under the Terms of Use.

Peptides are short chains of amino acids, usually between 2 and about 50 residues. They sit between small-molecule drugs and full proteins, and they behave differently from both — usually too fragile to survive the digestive tract and too large to cross membranes freely.

Every compound on Healthy Mango is a peptide or a peptide-adjacent research compound.

"Research Use Only" (RUO) is a regulatory label attached to material sold for laboratory investigation. It means the material was produced and sold outside the pharmaceutical approval chain, and that neither the seller nor a regulator represents it as suitable for human use.

RUO is not a warranty of identity, purity, potency, sterility, or safety. It is a legal statement about how the material is being sold.

No. The FDA approves specific pharmaceutical products, not molecules in the abstract. When a molecule (for example semaglutide) exists both as an approved product (Ozempic, Wegovy) and as a research-supply vial, those are legally, chemically, and supply-chain-wise different products. The approval attaches to the pharmaceutical product, not to the research vial.

No. Two peptides that differ by even a single amino acid can behave very differently in pharmacology, stability, and safety profile. Class-level generalisations only go so far; the compound page is the authority for a specific molecule.

A Certificate of Analysis (CoA) is a laboratory report summarising the tests performed on a specific production batch. A peptide CoA typically confirms identity (usually by mass spectrometry), reports purity (usually by HPLC), and sometimes covers water content and appearance.

The CoA is evidence about the specific sample the lab tested, on a specific date. It is not automatically evidence about every vial in the batch, and it is not evidence about safety.

No. A CoA reports the results of specific analytical tests under specific methods. A high purity number does not imply sterility. A confirmed identity does not imply endotoxin freedom. Even a complete panel (identity, purity, sterility, endotoxin) does not establish suitability for human use — no test a research supplier can run does.

Read a CoA as evidence for what it tested and treat every category of contamination or defect the CoA does not test as an unknown.

High-Performance Liquid Chromatography (HPLC) is a separation technique used to measure the purity of a peptide sample. The peptide is pushed through a column at high pressure and the components elute at different times; a UV detector produces a peak for each component.

The purity number on a CoA is usually the area under the main peak as a percentage of all detected peaks under a specified method.

Liquid Chromatography–Mass Spectrometry (LC-MS) combines a chromatographic separation with a mass spectrometer that measures molecular mass. For peptides it is the primary identity technique: the observed mass is compared to the theoretical mass calculated from the peptide's sequence.

Endotoxins are cell-wall breakdown products from Gram-negative bacteria; they can trigger strong inflammatory reactions even in nanogram amounts and are not destroyed by autoclaving. The standard test is the Limulus Amebocyte Lysate (LAL) assay (or a recombinant equivalent), reporting units per volume or per mass.

Endotoxin testing is distinct from sterility testing. A sterile product can still contain enough endotoxin to be pyrogenic.

Sterility testing verifies the absence of viable microorganisms. A sample is cultured in media that support a wide range of bacteria and fungi, and the media are inspected over about 14 days.

The test is destructive (the tested vials are consumed), and a pass is a statistical inference about the batch, not a guarantee about every vial. "Sterile-filtered" is not the same as "sterile."

Bacteriostatic water for injection is sterile water containing 0.9% benzyl alcohol as a preservative. The preservative slows (does not eliminate) the growth of bacteria that may be introduced when a needle enters the vial. It is used for repeated-access reconstitutions.

No. Sterile water for injection contains no preservative. It is intended for single-use reconstitutions where the entire vial is used at once. Substituting bacteriostatic water for sterile water (or vice versa) changes both the in-use time and the applicable contraindications.

Lyophilization is a manufacturing step that removes water from a peptide solution under low temperature and low pressure, leaving a dry cake or powder of peptide inside the vial. The peptide mass does not change; only the volume it occupies changes.

Every compound page on Healthy Mango describes a lyophilized vial as the default presentation. It must be reconstituted in a diluent before it can be measured in millilitres.

Concentration ties the mass on the vial label to the volume in the syringe. A 10 mg vial reconstituted in 2 mL of diluent is 5 mg/mL; the volume needed for a given research amount is that amount divided by 5 mg/mL.

Getting concentration right first, before touching a syringe, is what makes every downstream step safer.

Reconstitution is the step in which a fixed volume of a sterile diluent is added to a lyophilized vial so that the peptide dissolves into solution. Once dissolved, the solution can be drawn into a syringe and its volume can be measured. The peptide mass does not change during reconstitution — only the volume it occupies.

The "units" printed on a U-100 insulin syringe are hundredths of a millilitre. 100 units is 1.0 mL; 10 units is 0.1 mL. It is a volume scale, not a mass scale — a unit does not correspond to a fixed amount of peptide.

Confusing units-as-volume with units-as-mass is one of the most common sources of a wildly wrong dose. Always cross-check with the compound page or the Preparation Calculator's example values.

Because Healthy Mango cannot know your medical history, current medications, allergies, or laboratory values. A dose that has been reported in a published trial or in a practitioner reference is not, by virtue of appearing there, safe or appropriate for any specific reader. That is a clinical decision, not an editorial one.

The site describes what has been reported and what the arithmetic is. It leaves the decision to the reader and their clinician.

No. The Preparation Calculator performs arithmetic only. It computes concentration from vial mass and diluent volume, and it converts a reported research amount into an equivalent volume. It does not verify vial identity, purity, potency, or sterility, and it does not evaluate whether the reader is an appropriate candidate for the compound.

No. Purity is a specific analytical measurement of the fraction of a sample that is the intended peptide under a specific method. It says nothing about sterility, endotoxin content, or the vial's suitability for human use. A 99% pure vial can be contaminated or contain a wildly wrong mass.

Yes. Microbial contamination and endotoxin are usually invisible; visual clarity rules out gross particulate but not much else. A dry cake that looks intact and a solution that looks clear are consistent with a good vial, but they are not proof of one.

Contact the vendor directly and preserve any packaging, labels, and Certificates of Analysis as evidence. If the situation involves personal injury or a suspected poisoning, get medical or emergency help first and preserve the material for the treating clinician.

You may also send an informational report to support@healthymango.org so we can consider the vendor and product in future editorial coverage. Healthy Mango does not act as an enforcement authority.

Stop reading this website and get help. Call your local emergency number for any life-threatening symptom. In the United States, Poison Control is available 24 hours at 1-800-222-1222 for suspected overdoses or exposures.

Do not use Healthy Mango contact addresses for emergencies. Those addresses are staffed for editorial and legal correspondence, not urgent triage.

Animals differ from humans in metabolism, receptor distribution, immune response, and lifespan. A signal in a mouse is evidence that a human trial is worth designing; it is not evidence that the same result will appear in humans.

Some safety signals translate across species better than efficacy signals do. Compound pages label animal-only evidence as such (Level D on Healthy Mango's evidence scale).

Every compound receives an evidence level (A, B, C, or D) summarising the quality and quantity of the human evidence. Level A is strong human evidence with regulatory approval; Level D is preclinical evidence with little or no human data. The grading is deliberately simple and is a starting point, not a verdict.

A published study is a controlled experiment: it isolates one intervention and measures a pre-specified endpoint. A practitioner reference describes real-world clinical practice: what practitioners have used, at what doses, in what patterns. Both are useful. They are not the same weight of evidence.

Compound pages tag every value with the source category it came from (peer-reviewed, regulatory registry, practitioner reference, or calculated).
