A peptide amount in mg and a concentration in mg/mL describe different things. The first is a mass; the second is a mass for a stated volume. When you compare catalogue entries, keep the material name, listed content and presentation in separate fields.
This distinction is useful for BPC-157, KPV, Retatrutide and other named entries. It also prevents a picture of a vial or pen-style kit from becoming a substitute for the actual specification.
What do mg, mL and mg/mL mean?
| Unit | Describes | Question to ask |
|---|---|---|
| mg | Mass, expressed in milligrams | What material and reporting basis does the amount identify? |
| mL | Volume, expressed in millilitres | Is this actual liquid volume or container capacity? |
| mg/mL | Mass concentration | Which constituent and mixture volume does the value refer to? |
IUPAC defines mass concentration in terms of a constituent’s mass relative to the mixture volume. Read the primary IUPAC definition. A mass-only listing leaves the volume unspecified, so it cannot establish a liquid concentration on its own.
This page explains catalogue units. It does not provide preparation instructions, delivered amounts or a use schedule.
Confirmed catalogue amounts at a glance
| Named entry | Listed amount options | How to read them |
|---|---|---|
| BPC-157 | 10 mg | Listed content per unit; confirm selected presentation |
| KPV | 10 mg | Listed content per unit; confirm selected presentation |
| GHK-Cu | 50 mg / 100 mg | Listed content per unit; confirm selected presentation |
| Retatrutide | 30 mg / 40 mg / 50 mg / 60 mg | Listed content per unit; confirm selected presentation |
| Tesamorelin | 5 mg / 10 mg | Listed content per unit; confirm selected presentation |
Separate options are separate catalogue specifications. Retatrutide 30 mg and 60 mg identify different listed amounts; neither number establishes the concentration of an offered liquid. The Tesamorelin options likewise identify content choices rather than a timetable or comparative effect.
Ask which option and presentation are currently available. Retain the complete name: for example, the GHK and GHK-Cu comparison explains why a related name should not silently replace the named entry.
Container capacity is another field
A container may be described by capacity, while the supplied contents have their own specification. Keep a capacity label apart from any declared liquid fill volume. If a photograph or brief shows only a container size, ask for the missing content details.
For a vial or pen-style kit, request the named material, accepted amount basis and supplied component list. Confirm whether the enquiry concerns a standalone unit or a packaged kit. Do not infer an amount delivered by a device from its appearance or from a total milligram figure.
Blend totals need their components
A total amount for a blend does not tell you how much of each component it contains. Preserve the component names and amounts exactly as accepted. A ratio cannot be supplied by the product category or by the sum alone.
The Aurelis blend guide keeps unresolved specifications visible. If a blend is listed as specification on request, request that specification; do not assign a concentration or component breakdown from a similar-looking product elsewhere.
Use a short specification checklist
Record the exact peptide or blend name, listed content option, preferred presentation and requested quantity. For any liquid specification, request the actual declared volume and concentration basis separately. Ask for the matching batch identity and content records through our quality-documentation page.
That record connects the catalogue enquiry to the offered material. It also makes a revised quotation easier to compare: you can see whether the name, amount, format or another field has changed without treating all differences as “strength.”
Send an enquiry with the units intact
Include your selected named entry, amount option and preferred vial or kit format. Add your destination in the USA, Canada or Australia and request confirmation of current local availability. If a document uses a different unit, attach the original wording and ask what it represents.
