I want to start Gene Devine’s NO stack but having difficulty finding horny goat weed 60% 150 mg. In the thread you note prefer Vitamin Shoppe brand. However, when I went to their website Horny Goat Weed has only 10% Icariin and many other ingredients. I found Nugenix brand that was 40% but 300 mg capsules. Can you suggest brand or source that matches your NO stack? Thanks.
