What is MK-677?

MK-677 (Ibutamoren) is a non-peptide oral GH secretagogue — unique among GH secretagogues in that it's taken orally. Mimics ghrelin to stimulate GH and IGF-1 release with a 24-hour half-life for once-daily dosing. Produces significant, sustained GH and IGF-1 increases comparable to low-dose HGH. Dramatically improves deep and REM sleep — often the first benefit noticed. Main downsides: water retention, increased hunger, and potential blood glucose elevation with long-term use.

Dosing Protocols

Below are evidence-based MK-677 dosing protocols for different experience levels and goals. Always start at the lowest effective dose and assess tolerance before increasing.

Beginner: 10–12.5 mg before bed. Minimizes water retention.

Standard: 25 mg before bed. Most common dose.

Sleep Stack: 25 mg MK-677 + 100 mcg Ipamorelin before bed.

Reconstitution Guide

Proper reconstitution is critical for accurate dosing. Follow these steps carefully:

MK-677 is taken orally — no reconstitution needed

Available as capsules, tablets, or liquid suspension

Take 30–60 min before bed for sleep GH benefits

Standard dose: 10 mg (beginner) or 25 mg (standard)

Dosing Reference Table

Use this table to determine your exact injection volume based on vial size and BAC water amount:

Vial Size	BAC Water	Concentration	Low Dose Vol	High Dose Vol
10 mg/day	Oral	N/A	10 mg	N/A
25 mg/day	Oral	N/A	25 mg	N/A

Injection Site Guide

Recommended sites: Oral — no injection required

Rotate injection sites to prevent scar tissue buildup. Clean the injection site with an alcohol swab before injecting. Use a 27-29 gauge insulin syringe for subcutaneous injections. Pinch the skin, insert needle at 45-90°, and inject slowly.

Storage Guidelines

Lyophilized (powder) form: Refrigerate at 36–46°F (2–8°C). Protect from light. Most peptides remain stable for 1–2 years unreconstituted.

Reconstituted solution: Refrigerate immediately after mixing. Use within 4 weeks typically. Do not freeze reconstituted peptides — this may damage the peptide structure.

Frequently Asked Questions

Q: What is MK-677?

A: Oral GH secretagogue (Ibutamoren) mimicking ghrelin to raise GH and IGF-1 without injections.

Q: Cycle length?

A: 12–16 weeks with 4–8 week breaks. Some use 10–12.5 mg year-round.

Q: Best time to take?

A: Before bed — maximizes overnight GH pulse and makes hunger/lethargy side effects occur during sleep.

Q: Will it cause fat gain?

A: Water retention is common but not fat. Manage caloric intake since it increases hunger.

Q: Effect on testosterone?

A: No direct testosterone effect. Possible mild cortisol increase with long-term use.
