So about 6 months ago my friend bought a test booster from a store, testo fx or something, and has told me he hasn't been himself since.. Emotionally.. First I'm wondering if that's even possible cause i dont know much about over the counter test boosters and i believe they are crap... and second if it is possible, would a pct help in any way to get him feeling like himself? And other advice would be appreciated as well.
