Peptides 101
Peptides are chains of amino acids. The name of a compound alone does not establish its benefits, suitability or quality. Read each guide for its research context and the limitations of the available evidence.
Laboratory findings, animal research and human studies answer different questions. A product listing is not evidence of approval for a particular use.
Browse the compound guides →↑ All topicsUnderstanding reconstitution
Reconstitution means adding a specified liquid to a powder to prepare a solution. The required diluent, quantity, mixing method and usable period depend on the exact product.
Use the manufacturer’s product instructions and the pharmacist’s directions. Do not substitute a diluent or copy a mixing recipe from another compound. If instructions are missing or unclear, ask the dispensing pharmacist before preparation.
A vial and a pen cartridge are different containers. A disposable pen must not be treated as a refillable device.
↑ All topicsSyringe types & scales
A syringe may be marked in millilitres (ml) or in units for a specified insulin concentration. Check both its capacity and its smallest marked interval.
A unit marking is not a universal peptide dose. Ask the pharmacist to show the exact prescribed volume on the exact syringe supplied. FDA reports describe errors caused by confusion between milligrams, millilitres and syringe units. [1]
↑ All topicsUnderstanding mg, mcg & ml
- mg — milligram
- A measure of mass.
- mcg or µg — microgram
- A smaller measure of mass: 1 mg = 1,000 mcg.
- ml or mL — millilitre
- A measure of volume: 1 litre = 1,000 ml.
- mg/ml — concentration
- The mass of a substance in each millilitre of solution.
You can convert mg to mcg directly. Converting mass to volume requires the exact concentration; mg and ml are not interchangeable. These definitions explain labels and do not determine an individual dose.
↑ All topicsCommon measurement mistakes
- Confusing mg, mcg and ml.
- Assuming the same volume has the same amount of medicine in every product.
- Copying syringe markings from a different concentration.
- Misreading a decimal point or the spacing between scale marks.
- Using instructions for a different vial, cartridge or pen.
Confirm unclear measurements with the dispensing pharmacist before use. FDA has reported serious dosing errors with compounded semaglutide when concentrations and measurement units were misunderstood. [1]
↑ All topicsNeedle gauge & length
Gauge describes needle diameter; length is a separate measurement, usually given in millimetres. A higher gauge number generally describes a thinner needle.
Needle choice depends on the device, the prescribed route and the individual. Ask a qualified healthcare professional to confirm a compatible needle and demonstrate its use. A product’s vial strength does not tell you which needle to choose.
↑ All topicsInjection routes & sites
Subcutaneous means under the skin; intramuscular means into muscle. These routes are different and must not be substituted.
The suitable site and technique depend on the prescribed medicine and its instructions. Obtain a demonstration from a healthcare professional for your exact product. This page does not provide a universal injection technique.
Never share a pen. Use fresh, sterile single-use equipment as directed; changing a needle does not make a used syringe safe to share. [2]
↑ All topicsUnderstanding refillable pens
Some pens accept replacement cartridges; others are disposable. Identify the exact make and model before selecting a cartridge or needle.
For a reusable device, follow its supplied instructions for compatible cartridges, assembly, flow checks, dose selection and maintenance. Have a pharmacist demonstrate these steps. Do not assume that clicks or dial markings translate to the same amount across devices or concentrations.
Never refill a disposable pen or transfer a vial into a cartridge unless the product and device instructions explicitly support that use.

↑ All topicsStorage FAQs
Do all peptides need the same storage?
No universal temperature or shelf life applies to every formulation. Follow the exact product’s label and dispensing instructions.
Does mixing change the usable period?
It can. Check the product-specific instructions for the period after preparation and after first use. Record dates when instructed.
Can I use a product after a temperature excursion?
Ask the dispensing pharmacist or manufacturer to assess the product and the time and temperature involved before using it.
What if the label has no storage instructions?
Request written instructions from the supplier or pharmacist. Do not infer them from another peptide or a general online guide.
Beginner’s Guide
- Start with a name or topic. Use the homepage search or choose one of the five topic cards.
- Read the full guide. Look for the research context, supporting sources and limitations.
- Keep research and product details separate. The education library explains topics. The catalogue lists available product variants and enquiry options.
- Write down your questions. Personal treatment, suitability and dosing questions belong with a qualified healthcare professional.
Quick glossary
- Compound
- A substance with a defined chemical composition.
- Peptide
- A chain of amino acids connected by peptide bonds.
- Research evidence
- The observations and results reported by studies. A guide should make clear what kind of study supports a statement.
- Preclinical research
- Research conducted before human clinical testing, including laboratory and animal studies.
- Clinical research
- Research involving people. Its findings depend on the study design, participants and outcomes measured.
- Formulation
- The ingredients and presentation of a particular product.
Frequently asked questions
How do I find a specific guide?
Choose Search Compounds in the menu and type a name. Select View all to clear the search and topic filter.
Why can a guide appear in more than one category?
Topics organise the library. A compound may be discussed in more than one research area; placement is not a promised result.
Where are the products and prices?
The existing private catalogue contains product variants and listed prices. Final availability and pricing need confirmation from NeoMe.
Does the library provide a personal treatment plan?
No. These pages provide educational context, not individual treatment or dosing instructions.
