As already mentioned in the initial post, I don't do it consistantly but cycle it, 4 weeks I use the testo stack and then 4 weeks my creatine cycle, the one week off everything - rinse and repeat.
You can use Creatine Monohydrate all year round.
Creatine is the best researched supplement in the world. It is very safe, worst you can get is diarrhea when you take too much at once, and it works amazingly well for bodybuilding and strength. It's also dirt cheap. I take 5g morning + 5g evening on rest days and an additional 5g post workout on training days. There's no need to cycle it.
Testo booster:
Even if we assume for a moment that testo boosters were not a scam, it would still be stupid to use them because it's highly unhealthy to manipulate your hormones.
What people don't understand is that when it comes to hormones, more is not better.
Everyone of us has a perfect balance of hormones where the body feels like a well oiled machine. This balance is unique for each individual and genetically fixed. You can't alter it in any way. The further you get away from that balance, the more side effects you will see and the more drugs you will have to take to stay healthy and functional.
Some people have higher natural testosterone levels. Some people have lower natural testosterone levels. As long as your testosterone is exactly where your body wants it to be, everything is perfectly fine. If your testosterone level gets higher (!) or lower than your genetic sweet spot, you'll get sick and you'll eventually die if you don't correct it, because hormones play an immense role in a multitude of processes in your body.
That's why we have testosterone replacement therapy (TRT) which can counter health problems that are related to testosterone levels that are out of balance.
It is usually men with a high testosterone sweet spot that suffer heavily from age related hypogonadism. These guys often have severe symptoms of low T even if they still have higher T than guys with a low sweet spot.
People don't understand that testosterone is all about relativity. They see total numbers without context and try to pump their own numbers as high as possible. Is low testosterone bad? No. Is low testosterone bad in a guy that has a high T sweet spot? Hell yes, but so is high testosterone in a guy that has a low T sweet spot. If a low T sweet spot guy does TRT and he pushes his T too high than he will get seriously sick.
If your body is healthy and working exactly how it's meant to be, testo boosters, assuming they're not a scam (they are a scam), will give you zero benefits for weight lifting. You would only see benefits, if your T levels are out of balance.
But even then it's stupid to take these testo boosters. Testosterone, as a drug, is very well researched. Testo boosters are not. Today's men have access to 3rd generation medical testosterone which is much better than the stuff people used decades ago and the shady crap you can order in the dark web from an underground lab. Testo boosters have side effects and they're not produced under medical standards. For a guy with hypogonadism, using medical testosterone is much healthier than using a testo booster.
Also, real testosterone is cheap. A month worth of medical T will cost you $15 and it will be highly effective. That testo boosters cost you $100 per month and it will do nothing except damaging your liver.
