MK-677 (Ibutamoren) vs Syn-Ake
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
MK-677 (Ibutamoren)
MK-677, also known as Ibutamoren, is an orally active growth hormone secretagogue. Unlike peptides, it can be taken orally and has a long half-life, providing 24-hour GH elevation.

| Aspect | MK-677 (Ibutamoren) | Syn-Ake |
|---|---|---|
| Mechanism | Acts as a potent, selective agonist of the ghrelin receptor (GHS-R1a). Increases GH and IGF-1 levels without affecting cortisol. Mimics ghrelin's GH-releasing effects. | Acts as a competitive antagonist at the nicotinic acetylcholine receptor, reducing muscle contractions similar to Botox but through a different mechanism. Provides muscle-relaxing effects when applied topically. |
| Typical Dosage | Typical dosing: 10-25mg taken orally once daily. Often taken at night due to sleep benefits and appetite increase. | Topical: 1-4% concentration in serums or creams. Applied 1-2 times daily to target areas like forehead and crow's feet. |
| Administration | Oral administration (capsule or liquid). Can be taken with or without food. Long half-life allows once-daily dosing. | Topical application only. Should be applied to clean skin. Often combined with other anti-aging peptides for synergistic effects. |
| Side Effects | Increased appetite and water retention are most common. May cause lethargy, vivid dreams, and mild numbness. Can affect blood glucose and insulin sensitivity. | Generally well-tolerated topically. Rare reports of mild skin irritation or sensitivity. |
