Use Zhe Chem, they sell seti at $5.5/g at orders of 200g or moreThis is the price sheet that they gave me50g—USD 8/g100g—USD 7/g150g—USD 6/g200g—USD 5.5/gAll price includes shipping.I think if you contact Zhe from their ali baba site they will take a long time to respond.Contact a guy named Lewis ZheChem.lewis@hotmail.com he should get back to you quick.I just ordered 200g from them. If he asks who you are just say Khalil from HairLossTalk.com referred you.
