What is MK-677?

MK-677 (ibutamoren) is a non-peptide, orally bioavailable ghrelin receptor agonist used in long-duration GH/IGF-1 elevation research where parenteral dosing is impractical.

Mechanism of action

Orally bioavailable GHS-R agonist.

Primary research areas

Long-duration GH/IGF-1 elevation studies.

Research notes

  • Not a peptide; included for mechanistic completeness.

Third-party COA — testing in progress

Pending
The current MK-677 batch is with our independent laboratory (Janoshik Analytical / VidaLabs) for HPLC + Mass Spectrometry analysis. Published COAs for previously-tested compounds are available in our full COA library.

Need the batch-specific COA for your order? Email support@regena-peptides.com — we'll send it as soon as the lab returns the report (typically 5–10 business days after shipment).

What researchers say about MK-677

    COA matched batch number exactly

    Ordered three batches of BPC-157 over four months. Each shipment arrived cold-packed with a COA and the batch numbers cross-checked against the public testing database. Purity reported between 98.7% and 99.2% — consistent with what we measured in-house by HPLC.

    Fast UK delivery, clean reconstitution

    Discreet packaging, arrived in 48 hours to London. Lyophilised cake was firm, dissolved completely in bac water with no cloudiness. Dose math in IU on the calculator made repeat dosing trivial.

    Best documentation I've seen from a supplier

    We compared three suppliers as part of a sourcing audit. Regena was the only one with chromatograms, retention times and lab-named COAs published per batch. That's the standard the rest of the industry should meet.

    Good product, customs took an extra day

    Product itself is excellent — clean reconstitution, COA available. Customs added 24 hours which is outside Regena's control. Support replied within an hour when I asked for an update.

    Independent lab agreed with stated purity

    We sent a sub-sample to an independent lab. Their result was within 0.4% of the published Regena COA. That's a level of transparency you almost never see in research-peptide sourcing.

    Dr. S. PatelBirmingham, UK

    Cold chain held the whole way

    Temperature indicator strip in the package stayed in the green. Vials still chilled on arrival despite a 3-day route. Whoever packs these boxes knows what they're doing.
