I've run nolvadex in my cycles in the past and it always made my nips puffy then I tryed AR's L-dex in my last cycle @.25cc and no more puffyness,my gains seemed a lot more harder but my strength gains didn't seem as much as they usally do,do you all prefer nolvadex or L-dex,or letro,I know L-dex is effective in decreasing the production in estrogen and letro even more effective than L-dex,and from what I've read nolvadex does not prevent the production of estrogen only takes the etrogens place,what I need to know is do you need estrogen in your system to get the full effects from AAS and if so or if not what do you prefer or advise so far as treaments go ?
