Honestly, I just do not think that u really need anything more than a good strong PCT...The one that has just been proven returned levels to normal in 22 days...If you have a natty issue then maybe HCG blast would be the way to go...Now as far as off cycle test boosters are fine bc they will only allow you a small increase but your body will always stay close to homeostasis....I know that yohimbe works but it also jacks your blood pressure up and it messes with your heart rate too...Trib is great but like I said your body will only produce enough test for your daily fuctions and wont go much past the normal natty and thats just saying that you dont have lowT but an optimal level...you can fool yourself in thought but your body is not going to be so easily fooled...It knows right where its comfortable and supposed to be...otherwise we would need to use exogenous hormones to acheive the levels we need bc we could just use test boosters...Main thing is before you go putting something in your body, whether it b herbal or not its a good idea to research it and weigh the pros and cons to decide if its best for you
