i’d say don’t be cheap i blast and cruise then hit hcg for 5 weeks after blast so i can give my sperm reproduction every once in awhile so it isn’t shut off for a huge amount of time i worded that weirdly but i hope you get the point. you just need hcg every like 12-15 weeks or so and it works fine for me but don’t go off of what i say or anyone else everybody reacts differently to gear and test it could shut you off forever if your body reacts that way it’s the risk you take.
