Glow Peptides · Research Use Only
Encapsulated Research Materials
MK-677 is a synthetic small molecule, not a peptide, built on a spiro-indoline-piperidine ring system with a methylsulfonyl group and a benzyloxy side chain. Glow Peptides supplies it as encapsulated powder in a sealed research container. For laboratory research use only, not for human or veterinary use.

Composition • MK-677 (Ibutamoren) • Appearance: Encapsulated powder in a sealed research container
Supplier catalog specifications are not measured lot results. Read the specific report for its methods, findings and limitations.
Orders placed before 4 PM ET ship the same day, Monday through Saturday. Everything goes out in discreet, secure packaging, and a tracking number is emailed to you the moment your label is created.
Check the lot documents shown for the selected material and match the report lot number to your label. Documentation may be missing or held for clarification. A document on file does not itself establish independent analytical review, identity, purity, or sterility. Read the specific report for its methods, findings, and limitations; contact us to check availability if your lot is not listed.
Glow research materials are synthesized by our manufacturing partners in cGMP (current Good Manufacturing Practice) facilities using Fmoc solid-phase peptide synthesis, and each lot is then tested by an independent U.S. laboratory. Manufacturing conditions and analytical results are different things: check the lot-specific report for the methods and findings it records.
Store at room temperature, away from direct sunlight and moisture. No reconstitution or refrigeration required.
You're covered three ways. A money-back quality guarantee: if your material doesn't match its independent U.S. lab COA, we'll replace it or refund you in full within 30 days. Hassle-free returns: unopened, unused items in original sealed condition can come back within 30 days of delivery for a refund. And if a shipment arrives damaged, email us within 48 hours with photos and a free replacement ships once verified. Full policy.
