Chemyo RAD-140 vs MK-677: Compare the Product Specifications
Updated October 31, 2026
RAD-140 and MK-677 are different named compounds. A catalogue that lists both is not showing two names for the same material. Compare identity, supplied format and label units before comparing containers or a value pack. The distinction is especially useful when a search result places both names together without explaining what each product record contains.
Two records with different specifications
| Question | RAD-140 record | MK-677 record |
|---|---|---|
| Catalogue name | RAD-140 Testolone | MK-677 Ibutamoren |
| Solution label | 10 mg/mL, 50 mL | 25 mg/mL, 50 mL |
| Powder record | 1 g | 1 g |
| Nominal mass in the liquid bottle | 500 mg from the label values | 1,250 mg from the label values |
PubChem maintains separate chemical records for RAD-140 and ibutamoren. Ibutamoren is described as a non-peptide secretagogue; a shared place in a research-compound shop does not turn it into RAD-140. For the actual catalogue presentations, see the RAD-140 50 mL solution and MK-677 50 mL solution. These labels establish the intended order format, not a clinical comparison.
A shared bottle volume does not mean equal contents
Both liquid records state 50 mL, but the labelled concentrations differ. A comparison based only on the bottle size misses that difference. The nominal totals above are multiplication of printed values. They do not verify concentration, confirm a solvent composition or establish the amount actually present in a specific supplied bottle.
What does a value pack mean?
The RAD-140 and MK-677 value pack describes separate labelled items. It is not a single blended solution, a validated combined method or a recommendation to use the materials together. Read each component separately, then confirm both are part of the current offer. A carton illustration does not replace an itemised inventory record.
Choose the comparison that answers your question
For an order enquiry, compare exact material, form, quantity, documentation and current delivered price. For a laboratory process, rely on the applicable validated method and complete specification. This page does not compare personal effects or recommend a treatment, cycle or stack. FDA warns against consumer use of unapproved products marketed as SARMs; a supplier label does not establish an approved medicine.
Use the quantity comparison guide when mass and volume are mixed, and documentation guidance when the missing question is identity or measured content.

Turn the comparison into two clear product questions
When asking Chemyo about these records, identify RAD-140 and MK-677 separately. State the requested format and quantity for each, then ask about the exact detail that needs clarification. A shared bottle volume or pack illustration does not establish the same identity, composition or applicable evidence for two different materials.
For a current price comparison, keep both complete specifications beside the quoted totals. Include container count and relevant order charges. This helps distinguish a commercial comparison from a claim of chemical or clinical equivalence; the guide addresses the catalogue records and does not establish that either material can substitute for the other.
