MK-677 Tracker
MK-677 is an orally active growth hormone secretagogue — not actually a peptide, though it is almost always grouped with them. This page covers its half-life, what that timescale means for keeping a usable record, and how it changes the shape of a log — not what to take or how much.
What MK-677's timing means for tracking
Two things set MK-677 apart from everything else on this site. It is taken orally, so there is no vial, no bacteriostatic water, and no syringe math at all. And it is not a peptide — it is a small molecule that happens to act on the same pathway, which is why it ends up in peptide catalogues anyway.
Its half-life is around 24 hours, which is long enough that levels build across consecutive daily entries and reach a rough steady state after roughly five days. That is a genuinely different pattern from the injectable secretagogues, which clear within hours.
For recordkeeping the oral route simplifies things: no concentration to store, no unit count to recompute when a vial is mixed differently. What matters is the date, the amount, and consistency — because at a 24-hour half-life a missed day is a visible dip rather than a rounding error.
What to capture in the log
- Record date and amount. There is no concentration or unit count to track for an oral compound.
- Consistency matters more here than for short-acting compounds — levels depend on the previous few days.
- Expect roughly five days before the pattern settles.
No reconstitution needed
MK-677 is taken orally, so there is no vial to mix, no bacteriostatic water, and no syringe unit conversion. If you are tracking injectable compounds alongside it, the reconstitution calculator covers those.
Frequently asked questions
What is the half-life of MK-677?
About 24 hours, long enough that daily entries overlap and reach a rough steady state after roughly five days.
Is MK-677 a peptide?
No. It is an orally active small molecule that acts on the growth hormone secretagogue pathway. It is grouped with peptides by convention rather than by chemistry.
Do I need to reconstitute MK-677?
No. It is taken orally, so there is no vial to mix, no bacteriostatic water, and no syringe unit calculation.
Is Ibutamoren the same thing?
Yes, Ibutamoren is another name for MK-677 and PepTrack records it as an alias.
