1-Andro 2-Step converts to 1-Testosterone, which is a DHT derivative. So it is *possible* that it may affect your hairline. It doesn't convert to Estrogen, therefore it is a "Dry" compound. The supplements available to combat the negative effects of DHT, would be those related to the Prostate: Saw Palmetto, Stinging Nettle, Pumpkinseed Oil, etc... There is also a shampoo that claims Anti-DHT properties, but I have no idea if it works. Taking 1-Andro 'Solo' could also have lethargy as another side effect.
