Reference catalog
An educational index of what actually circulates: compound classes, the vial sizes they are sold in, lyophilized powder versus pre-mixed solution, and the diluents and supplies that go with them. Last updated .
No vendors, no prices, no purchase links. We deliberately name no supplier, brand or storefront. Every illustration here is a schematic we drew, not a product photograph. This page exists so you can identify what you are holding and what should be verified — not so you can shop.
Six formats cover essentially the whole market. Each fails in a different way.
Freeze-dried cake or loose powder in a sealed vial. The dominant format. Mass is the label claim; you supply the water.
Watch forA cracked, shrunken or oily-looking cake suggests a broken cold chain or a failed freeze-drying cycle.
Already reconstituted, sold ready to draw. Convenient and the least stable — potency falls with time in solution.
Watch forCloudiness, floaters or any colour where the compound should be clear.
Pharmacy-channel presentation for approved GLP-1 products, dosed in clicks or fixed increments.
Watch forBatch numbers that do not match the carton, or a dose dial that does not click cleanly.
Oral, sublingual and intranasal formats. Mass per unit is small and excipients dominate.
Watch forEffectively unverifiable by appearance; assay of the finished unit is the only real check.
Cosmetic-strength peptide in a carrier base, usually GHK-Cu or signal peptides.
Watch forConcentration is often stated as a percentage of a blend, not of active peptide.
Two or more actives in one vial under a single total-mass claim.
Watch forThe ratio between actives is the number that matters and is almost never disclosed.
The highest-volume category on the public market. Sold as lyophilized powder in single- or multi-dose vials, and as pre-mixed pens through licensed pharmacy channels.
GLP-1 receptor agonist
Dual GIP / GLP-1 receptor agonist
Triple GIP / GLP-1 / glucagon agonist
GLP-1 receptor agonist (daily)
GHRH analogue (visceral fat)
hGH fragment (176–191)
Typically small-milligram vials of lyophilized powder. This category showed the highest failure rate in our own sample analysis.
Pentadecapeptide, body-protection compound
Actin-binding repair peptide
Copper tripeptide
Immune-modulating peptide
Alpha-MSH tripeptide fragment
Sold in larger milligram loads than most peptides, and the category most often shipped as an already-dissolved solution.
Coenzyme / cellular redox
NAD+ precursor
Tetrapeptide (pineal)
Mitochondria-targeted tetrapeptide
Mitochondrial-derived peptide
Often sold as blends, which is what makes them hard to verify: two or three actives in one vial with a single total-mass claim.
Selective GH secretagogue
GHRH analogue
GHRH 1-29
Assorted secretagogues and appetite agents
The half of the market nobody verifies. A correct peptide in the wrong diluent, or with a compromised stopper, fails just as surely.
Sterile water with 0.9% benzyl alcohol
Preservative-free diluent
Isotonic diluent
Fixed-needle syringe
Transfer consumables
Packaging components
Ancillary supplies
Common labelled loads, the water volumes typically paired with them, and the resulting concentration. Educational reference only — follow the instructions from your prescriber or pharmacy, not this table.
| Labelled size | Typically used for | Diluent volume | Concentration |
|---|---|---|---|
| 2 mg | Repair peptides, secretagogues | 1–2 mL | 1–2 mg/mL |
| 5 mg | Most common all-purpose vial | 2 mL | 2.5 mg/mL |
| 10 mg | Repair peptides, mid-tier GLP-1 | 2–3 mL | 3.3–5 mg/mL |
| 15 mg | GLP-1 / dual agonist | 1.5–3 mL | 5–10 mg/mL |
| 20 mg | GLP-1 / dual agonist | 2–4 mL | 5–10 mg/mL |
| 30–60 mg | High-load dual agonist | 3–6 mL | 10 mg/mL |
| 100–1000 mg | NAD+ and precursors | 2–10 mL | 50–100 mg/mL |
Nothing on this page tells you what is inside your vial. Labels, cakes, crimp seals and vial sizes are all trivially reproducible. Content and identity require an assay.
