Some supps may give a libido boost, so folks think their test is being boosted.
Most of the studies are bullshit also, even on proven supps. ("Subjects testosterone was boosted 10% for exactly 9 minutes" etc).
Some adaptogens can help with recovery, etc. (Real Ecdy). All the Turkesterone going around today is pure bullshit as we're seeing.
This shit makes a comeback every decade for all the noobs who missed it the first time around.
Some supps you can feel though. I had a trial/sample envelope of "Nutrex Alpha-Pump" shit.
I took it this AM as its "pump-only" w/ no stims.
I dont think I ever got a pump like this before. I dont happen to train for pump like some do, but arms and shoulders today, veins were popping.
Even more so than BHanks veins.
Might just be the glycerol in the product, I dont know. The thing is, some shit you can feel, but the effects are very short lived mostly.
Especially for these "plant anabolics".
