Adamax vs FGL
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Adamax
Adamax is a modified version of Semax with an adamantane group attached, designed to enhance its nootropic effects and extend duration of action compared to standard Semax.
Full details →FGL
FGL (FG Loop) is a synthetic peptide that mimics the neural cell adhesion molecule (NCAM) FG loop region. It promotes neuroplasticity and has shown cognitive-enhancing effects in research.

| Aspect | Adamax | FGL |
|---|---|---|
| Dose Range | 200 mcg–750 mcg | 500 mcg–1 mg |
| Frequency | 1x daily | 1x daily |
| Cycle Length | 2–4 weeks | 4–8 weeks |
| Route | intranasal | intranasal |
| Mechanism | Similar to Semax - enhances BDNF expression and modulates dopamine/serotonin systems. The adamantane modification may increase lipophilicity and CNS penetration. | Binds to FGFR1 (fibroblast growth factor receptor 1) to activate downstream signaling cascades that promote neurite outgrowth, synaptic plasticity, and neuronal survival. |
| Typical Dosage | Intranasal: 100-500mcg 1-2 times daily. Lower doses than standard Semax may be effective due to enhanced potency. | Research protocols have used subcutaneous doses ranging from 1-10mg. Intranasal administration also studied. Optimal dosing not established. |
| Administration | Intranasal spray is most common route. More stable than standard Semax. Often used for acute cognitive enhancement. | Subcutaneous injection or intranasal administration. Research compound with limited human dosing data. |
| Side Effects | Similar to Semax - possible irritability, hair shedding, or overstimulation. May have stronger effects than standard Semax. | Limited human data available. Animal studies show good tolerability. |
