How many units of MK-677 (Ibutamoren) should I draw?

It depends on your vial size, BAC water, and dose. For a 25mg vial with 0mL BAC water, a beginner dose of 10mg is typically 0 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to MK-677 (Ibutamoren)?

The standard amount is 0mL of bacteriostatic water for a 25mg vial. More water gives a more dilute solution — easier to measure small doses. Less water means fewer injections per vial. Adjust the BAC water slider in the calculator to see how it changes your syringe units.

How long does a MK-677 (Ibutamoren) vial last?

At a beginner dose of 10mg daily, a 25mg vial lasts about 2500 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for MK-677 (Ibutamoren)?

Most people use a U-100 insulin syringe (1mL / 100 units). For very small doses, a U-50 or U-30 syringe gives better precision. The calculator adjusts units automatically for whichever syringe you pick.

Pharmacokinetics — Active Dose Over Time

t½ = ~5 hours (IGF-1 elevation lasts ~24h)

After 1 half-life (5h): 50% remainsAfter 2 half-lives (10h): 25% remainsAfter 3 half-lives (15h): 12.5% remains

At a 15mcg dose: 50% = 8mcg remaining after 5h. Recommended frequency: Daily.

Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

MK-677 (Ibutamoren) Dosing Protocol

Level	Dose / Injection	Frequency
Beginner	10mg	Daily
Moderate	15mg	Daily
Aggressive	25mg	Daily

Note: Oral GH secretagogue — not a peptide, but a non-peptide ghrelin mimetic. Often available as capsules or liquid. No injection required. Take at bedtime to minimize hunger side effect. Monitor fasting blood sugar.

About MK-677 (Ibutamoren)

MK-677 (Ibutamoren) is an orally active, non-peptide growth hormone secretagogue that mimics ghrelin signaling. Unlike injectable GH peptides, it's taken by mouth and produces sustained 24-hour elevation of GH and IGF-1 levels. A single daily dose raises IGF-1 by 40-60% within weeks. It does not suppress natural GH production and can be used long-term, though it increases appetite and may affect insulin sensitivity.
