I just read a thread about test enan and when it begins to work. My question is why do you not feel it until 4-5 weeks later? The steroid is available for the body to use immediatley after injection and is carried into the bloodstream over a 4-6 day period. Is the reason is that you have to raise your test levels consistentley over a prolonged period? Someone with knowlege of this please let me know why this is. Thanks
