Dosing
A common research range for FGL is 200 mcg to 1 mg once daily. Experimental; limited human use data. These figures are reference points from published literature, not a prescription — your protocol should be set with a licensed provider.
Reconstitution
A typical reconstitution for FGL is 5 mg of peptide in 2 mL of bacteriostatic water, giving roughly 2.5 mg per mL. Vial's built-in calculator works out the exact syringe draw for any vial size and dose.
Half-life
FGL has an approximate half-life of 1.5 hours. Vial plots the real concentration curve from your logged doses so you can see peak windows and when levels taper.
Storage
2-8°C post-reconstitution.
Reported side effects
- Unknown human profile
Contraindications
- Pregnancy
