Zero, none, nada. Anything that draws the attention of a deer's nose is my enemy! 
Results????If I do decide to use scent its Tink's 69 placed on a cotton ball in an old 35mm film case circling my stand at 15 yards with a minimum of 6 film cases. Its been years since I've used any.
Had a doe circle my stand sniffing each film canister. Once she offered the perfect quartering away shot I stuck her with an arrow. Watched her bound away and stop 50 yards out looking around. She dropped right there after a minute or two. As I was giving her a few minutes to die a young buck came in and circled the scent canisters just as the doe did just minutes before. 15 yards out he circled my stand stopping at each scented spot and gave it a good sniff. I only had one tag so I let him walk. He found her scent and followed it to her body. "Sorry to ruin your date young fella!" Once I got down from my tree stand he left the area.Results????
Same results with nose jammer myself. A friend of a friend had similar results as yours so I said F it and bought some too. I wasn't seeing many deer that season anyways so I wasn't worried about messing things up if it didn't work.For Whitetails... IMO Best Scent Is No Scent.....
I have seen it work though... like anything you have to have some faith in whatever it is "new" your introducing.... one way to build confidence is by doing.. trial and error.... gaining your own personal experiences.. I ultimately decided, via my gained personal experiences over the years; when it comes to introducing Scent to Whitetails... the benefits never seemed to outweigh the overall risk of ruining a hunt. The only commercial and/or DIY scents I tinker with are for Trapping... Have you ever sat any traps or know of anyone that does? If not... You might want to consider befriending a fur trapper in your area especially if you want to learn/witness how certain/specific scents are chosen and deployed ....
BTW... on the subject of Scent. I've personally experienced positive results with Nose Jammer... Yep! Believe It Or Don't....... I was given a aerosol can of Nose Jammer as a Gag Gift a few seasons back. The very 1st time I put it to use was during Bow Season out of a Bull Blind setting on the ground. It was a really cold/frosty morning with very little wind speed. I had made it to the blind clean and sprayed the "perceived" downwind side of the blind and both sides with NJ.. I had 2 separate doe groups come in as close as 7 yds and never spook. The older doe would tilt their heads up sniffing and at times be facing my blinds general direction. None of deer ever busted or blew. I admit it was a super still morning and the low/zero wind speed may have played a roll. Overall I considered the NJ involved interaction with multiple deer that morning as a positive one.... The reason I decided to use NJ on that particular hunt was due to the forecasted lack of wind speed. I'm fairly convinced my scent was capable of covering those 7-10 yds to ruin the hunt. Both family groups exited the plot without incident.
My other Nose Jammer experience involved spraying the bottoms of my rubber boots. I had a fairly decent hike to a ridge top where a 2 man deer stand was located. I made sure to not spray the bottom of my rubber soles until after I had crossed all the creeks. I had just gotten settled when I picked up movement in the same vicinity/trail I walked in on that morning. I watched a young button buck-nose to the ground cover my every step. Bird dogging my trail to the base of my ladder. He smelled the first 3 rungs of the ladder then hung around feeding in the plot below me. I Learned a good lesson that day... I don't use Nose Jammer on my boots anymore.. I can see using it out west or open country during a spot and stalk scenario... Damnn-dest thing is that the Nose Jammer I was using smelled like sugar cookies! Way better than sardines, tuna oil, etc. Best Of Luck! Don't let anyone talk you out of an experience with Scent.. I highly recommend that you research as much info that you can get your eyes on. You can also extract urine fairly easily from deer that your or others in your camp harvest.
