You will have natural testosterone production, since using The ONE is NOT going to shut off your natural testosterone production (bloods from users have shown this).
Using a natural testosterone booster is NOT going to impair your natural testosterone production. You WANT to be using one, so that you restore your normal functioning and HPTA as soon as possible.
If Activate Xtreme takes 2 weeks to kick in, then it would be recommended to start it 2 weeks before the end of your cycle. You would have to be careful though, since Activate Xtreme contains nettle root: Nettle lowers SHBG, and the lower levels feedback by increasing estrogen levels, which can lead to gyno.
If you are NOT going to use Activate Xtreme and were only going to use ONE testosterone booster, then I recommend Drive (as it also increases you cAMP levels).
