Mixing & calculations

No validated recipe is established for arbitrary research vials. The calculator shows concentration, not suitability or shelf life.

Simple syringe and pen calculator

Choose your device and enter your known values. One result appears below.

You know the total solution volume. Calculate the scale mark for your entered amount.

Which syringe or pen?

More syringes

How much substance is in the vial?

Total amount on the label—not the container size in ml.

What is the total solution volume?

This is the total solution after dissolving, not automatically the water to add. Follow the specific product's instructions for preparation.

Which known amount do you want to convert?

Your known input. The calculator does not choose a suitable amount.

Complete the three number fields to see a result.

The calculator chooses neither a dose nor a mixing liquid. It does not check sterility, stability or suitability for use.

What the units mean

mg / µg = substance amount. 1 mg = 1,000 µg.
ml = liquid volume, not substance amount.
U / clicks = device markings. Their meaning depends on the device scale.

Calculation and extra figures

Complete the three number fields to see a result.

Scale and precision notes

Arithmetic does not establish measurement accuracy. Displayed numbers may be rounded; very small numbers use scientific notation. Intermediate values may not be readable on your device. Do not round fractional clicks up or down.

U-100 is used as a volume scale: 100 U = 1 ml. It is not the substance amount.

Copy this value from your pen's instructions. A 3 ml cartridge does not tell you the volume delivered at 60 clicks.

Formulas and individual stepsOpen only if you want the deeper explanation.

Formulas used

Concentration (µg/ml) = vial mg × 1,000 ÷ fluid ml
Volume (ml) = target µg ÷ concentration
U-100 units = volume ml × 100

Mixing process described by the reference

Verify inputs

Independently check label, fluid, expiry information and planned volume. Do not use unclear or damaged products.

Disinfect stoppers

The reference calls for separate alcohol swabs and sterile single-use materials.

Add fluid slowly

The calculated fluid is described as running down the inside wall rather than being forced directly onto the powder.

Dissolve gently

The vial is rolled or swirled gently, not shaken, until no visible solids remain.

Inspect visually

Cloudy, discoloured or particle-containing solution is discarded. Clarity does not prove sterility or identity.

Label and store by product data

Record concentration and date. Reliable manufacturer or pharmacy information takes precedence.

An internet guide cannot ensure aseptic preparation. Bacteriostatic water, sterile water and approved product diluents are not interchangeable; benzyl alcohol may be unsuitable for some people.

See calculation examplesFollow sample figures to understand mg, ml and scale markings.

Documented vial and fluid examples

Reconstitution & quantitiesOpen basics, units and sources

Explained in very simple termsBefore reading any number: this page reports what a product label, study or online community states. It does not say what any person should use.

Amount

mg or µg describe the mass of a substance. That is not the same as ml of fluid or U on a syringe. The number is only the amount stated by the identified source.

Interval

The interval only describes the time stated between two points. For example, once every 7 days does not mean daily and never justifies catching up or doubling.

Cycle

A cycle is a stated period that may include breaks. A community cycle proves neither effectiveness nor safety and does not prevent long-term risks.

Reconstitution

Reconstitution means mixing powder with a defined volume of fluid. This changes concentration, not the total amount in the vial. On U-100, 100 U equals exactly 1 ml of volume.

Not a guide to misuse

All community figures are shown only to place widely circulated online protocols in context. They are not instructions for self-use, injection, performance enhancement or any other misuse. Approved figures apply only to the exact named product, approved indication and medical supervision.

Research, risks & more detailsMechanism, adverse effects, storage, comparisons and common questions.

Mechanism: what is supported and what does not follow

Endogenous neuropeptide acting at VPAC receptors

VIP is classified as “Endogenous neuropeptide acting at VPAC receptors”. Influences vascular, intestinal, pulmonary and neural signalling. Therapeutic uses and analogues remain under clinical study. This describes the investigated pathway but does not validate a community use, amount, route or combination.

VPAC receptor signalling

This studies how binding to VPAC receptors mediates effects on blood vessels, digestion, and immune function, similar to a signal reaching several organ systems at once. Blood flow and inflammation markers are measured in lab and clinical models.

Vascular, lung, and gut signalling

This examines how a signal affects blood vessels, airway tissue, and the digestive tract at the same time, similar to one dispatcher relaying instructions to several different departments at once. Researchers typically measure blood flow, airway function, and gut activity in laboratory or clinical models.

Neuroendocrine signalling

This examines how the nervous system and hormone-producing glands communicate with each other, similar to a two-way phone line connecting the brain to distant organs. Researchers typically measure hormone levels in blood alongside markers of nervous system activity.

What communities discuss

These themes describe discussions and vendor claims. They do not prove benefit, safety, product identity or suitable use.

General wellness forums

Broader wellbeing impressions such as mood, sleep, and general feeling after using various products are exchanged here, usually without structured tracking. Such general impressions are not a substitute for targeted clinical examination.

Biohacker and longevity forums

Users compare self-assembled combinations of peptides aimed at influencing ageing processes or energy levels, often based on blood tests or subjective wellbeing scales. Personal self-experiments and marketing promises do not replace controlled long-term human studies.

Source and purity discussion

Discussion covers which vendors are seen as more trustworthy and how purity test results differ between batches. Such community assessments are based on limited samples and do not replace independent lab testing of each individual batch.

Adverse effects and safety risks

Reproductive, vasoactive or fluid-regulating signals can affect hormone axes, blood pressure, heart rate, fluid balance and pregnancy; risks depend strongly on route and indication.
Local reaction, infection, abscess and contamination are possible with any injection that is not professionally manufactured and administered.
A label or clear appearance does not exclude unknown purity, wrong identity, endotoxins or concentration errors.

Do not self-use / obtain clinical review

Pregnancy or fertility planning, cardiovascular disease, electrolyte/fluid disorders and hormone-sensitive disease require indication-specific medical oversight.
Acute symptoms, allergic reaction, breathing difficulty, chest pain, neurological deficits or severe abdominal pain require immediate medical care.
Children and adolescents, pregnancy/breastfeeding, and people with relevant disease should not be part of unsupervised experiments.

Monitoring and laboratory markers

Depending on the objective, vital signs, fluid balance, electrolytes, reproductive hormones and clearly defined clinical endpoints may be monitored.
Baseline, objective, measurement timing and stop criteria must be defined professionally in advance. Individual laboratory values cannot compensate for unknown product quality.

Evidence boundary

In clinical trials

Therapeutic uses and analogues remain under clinical study, without broad approval.

Clinical evidence

The substance is currently being studied in structured human clinical trials, but a general approval does not yet exist.

VIP acts through VPAC receptors on vascular, intestinal and pulmonary signalling, unlike oxytocin, which primarily governs reproductive pathways.

Storage and stability

The manufacturer label and prescribing information take priority. Storage instructions from a different product do not transfer.
Unapproved vials often lack dependable stability data before and after mixing; ‘2–8 °C’ or ‘28 days’ is not a universal standard.
Do not use after seal damage, particles, cloudiness, discoloration, unknown date or interrupted cold chain. Visual inspection does not prove sterility.

Troubleshooting and common errors

U-100 units measure volume, not drug amount: 100 U equals 1 mL. A wrong concentration makes every unit figure wrong.
Do not shake or dilute further to ‘fix’ cloudiness, particles or uncertain solubility; discard and obtain professional clarification.
Do not calculate a double or extra amount to compensate for missed use or an uncertain injection.
Without a COA, clear supplier, correct label and consistent vial information, identity is not confirmed.

Regulatory status and WADA

Comparison with related substances

Combinations / stacks

Combinations change effects, adverse effects and laboratory values; evidence for one substance does not establish the safety of a stack.
Overlapping pathways may add up. Hormonal, glucose, blood-pressure, coagulation, immune and sedating effects are important potential interactions.
Non-standardised blends prevent separate dosing, cause attribution and dependable reconstitution.

Frequently asked questions

Is an amount shown here a recommendation?

No. This page separates approved product information, study protocols and community information. No number or calculator is an individual dosing recommendation.

Does the U-100 calculator prove correct use?

No. It only converts mass, volume and syringe scale. It cannot check identity, purity, sterility, stability, solvent or medical suitability.

Can this profile be combined with other substances?

Safety of a combination cannot be inferred from a single-substance profile. Overlapping pathways, medicines and undefined blends can increase risk.

Which source controls when information conflicts?

For approved medicines, the current prescribing information and treating professional control. For research substances, conflict shows that no dependable self-use standard exists.

Are community claims clinical evidence?

No. Anecdotes can generate questions but do not replace controlled studies, regulatory review, or identity and quality testing.
