Laxogenin is good for reducing joint pain and increasing joint mobility, when applied transdermally, but it won't help you much in regards to mucsle growth.
If you're looking for supps to help improve muscle gains/size then look into things like Arachidonic Acid, Phosphatidic Acid and EpiCatechin products. Gotta make sure your diet and training are on point too. Supplements will only help to a certain degree, but when combined with the proper nutrition and training can easily help you make over average gains.
If you're just looking for cortisol control/reduction the look into things like Reduce XT, Ashwagandha/KSM-66 and transdermal 7-Keto.
