Endocrine side effects have included inhibition of endogenous testosterone release by means of feedback inhibition of pituitary luteinizing hormone (LH). Large doses of exogenous anabolic steroids may suppress spermatogenesis through inhibition of pituitary follicle stimulating hormone (FSH). The androgenic activity of anabolic steroids may decrease levels of thyroxin-binding globulin and result in decreased total T4 serum levels and increased resin uptake of T3 and T4. Free thyroid hormone levels remain unchanged and there is no clinical evidence of thyroid dysfunction. [ Ref ]
While a bit higher in price Geneza brand stuff is very good, and has less PIP and post injection problems than anything else I’ve tried. However if you’re budget shopping everything else is of comparable potency, but just be careful because it will require a bit more caution to avoid swelling and PIP.
As far as orals go I highly recommend British Dispensary. The price is impossible to argue with and the product kicks fantastically well. However for AI’s and SERMs I suggest Geneza’s stuff. Their clomid, and armidex got be back up and running again in only about 4 weeks after a HARD 1 year long cycle/cruise.
