Currently we don't make anything for muscle building per say. But our products like G-Force and TF-1 that promote deep sleep, will help being that sleep is one of the most important steps to building muscle. We are in the process of releasing Adrenoforce our cortisol control Transdermal that will help in that area. I just got finished running a bottle of Metamorphosis along with a CKD diet and I have shed some decent BF% while keeping my weights up. LMK if I answered your question, thanks for the interest.
