I bought n-acetyl-epitalon (listed as just epithalon) from China. 600mg very cheap at 12.8 us dollars per 50mg epitalon vial although the minimum order was 200 us dollars, so I also bought thymulin.
I injected it and didn't feel anything although my father yawns and feels a bit sleepy after each of his epitalon injections.
Other users report increased energy, dreaming, sleep, etc., but neither myself nor my father experienced that.
