Most times Gibberellic acid comes in a powder form and you mix it yourself to the desired strength. That is a very fair price for that amount, if it's 10 grams? Are you sure it's not .1 gram?
Try mixing it with distilled water at different strengths. Keep the mixed formula in the refrigerator or the powder in a cool dry place. It should keep fine for an indefinite time period. Are you sure it's 10g? That seems like quite a bit. Usually a 1G. package is about that price.
I mixed .05g with 12 ounces of water to make a 1000ppm solution or 24 ounces of water to make a 500ppm solution. It's very concentrated chemical and a little bit goes a long way. I have used 500ppm most effectively on temperate type of sundew, pinguicula, and sarracenia seeds to help break dormancy and avoid a long cold stratification period by soaking the seeds in the solution for about 8- 12 hours before sowing. You can experiment with different techniques. I have also sprinkled some seeds into the dry powder to coat them lightly before sowing. Keep the plants separate from the rest of your other pots of plants because the solution stays in the soil and could affect the growth of your other plants if the solution leeches out and gets to them.
Hope that this helps.
