Typical oral or sublingual dosage: 200500 g once or twice per day 68 week cycles Take on an empty stomach for better absorption This route is often chosen for gut inflammation, leaky gut, or ulcer recovery, since the peptide interacts locally with digestive tissue
Reported side effects include: Injection site irritation Headaches Nausea Fatigue More importantly, long-term data is limited
