Andarine and Ostarine are separate research identities. Andarine is commonly indexed as S4 or S-4; Ostarine is indexed as MK-2866 or enobosarm. Similar-looking names should not be treated as a spelling correction for one another.
Match identity before concentration
| Full reference | Alternate code | Listed liquid | Listed powder |
|---|---|---|---|
| Andarine | S4 / S-4 | 50 mg/ml · 50 ml | 1 g |
| Ostarine | MK-2866 | 25 mg/ml · 50 ml | 1 g |
Start with the complete identifier
The shorter label on a purchasing list can hide the distinction. Record Andarine S4 or Ostarine MK-2866 in full so the order, receipt and inventory label all refer to the same intended material.
The Andarine listing and Ostarine listing explain the catalog entries separately. Their shared research category is not evidence of equivalence.
Read the solution concentration for each item
The liquid product records use different labeled concentrations for these two materials. A shared 50 ml bottle volume does not make the supplied compound amount identical.
Use the concentration and volume guide when checking the labels. That calculation concerns purchasing quantities rather than personal-use amounts.
Powders require a different comparison
The powder entries are supplied by mass, not by a prepared liquid concentration. A 1 g label does not specify a solvent or method of preparation.
Review Andarine powder and Ostarine powder as separate material records. Keep the product name attached to the mass in any comparison.
Avoid unsupported outcome rankings
A name comparison does not establish which material is more suitable for a person or an experiment. Any research conclusion needs the actual study context and a method-specific assessment.
This article supplies no cycle, dose or personal-use recommendation. Materials in this catalog are intended for laboratory research only.
Select the listing the laboratory requested
Check the requested identity, format and quantity, then review the product-specific composition and storage notes. A related code should remain a separate option, not an automatic replacement.
