Happy so far

I like their creatine it’s not always easy to find a flavorless creatine so I make sure to always have that in my order. The pre work out is nice I get a decent boost but not a crazy jittery rush I like the low caffeine. I get a good pump and can power through tough sets. The flavor is a little rough but I like it. I’m not sure about the test booster yet I’m on my third week and not sure if I feel any changes.

Yes, Vintage Boost™ is a non-steroidal product for adults wishing to boost their testosterone to help drive gains in muscle size, strength, energy and libido.


First, it has been suggested that the maximum amount of creatine your muscles can absorb at once is roughly around 5 g. Your muscle cells contain tiny proteins, known as transporters, that pull creatine inside the cell. Once these become saturated with creatine, they need a few hours to process it before they can take on another 5 g dose. For this reason, we suggest allowing at least 4 hours between doses. Second, creatine requires adequate water to produce maximum results. We advise drinking 10-12 oz with each 5 g dose. Finally, eating carbohydrate (“carbs”) enhances the uptake of creatine by your muscles. This is because it stimulates the release of insulin, which in turn stimulates the creatine transporters in your muscle cells. A simple way to take advantage of this is to take each dose of creatine right after eating a carbohydrate-containing meal or snack. Carbs that digest quickly work best. Examples include breakfast cereals (e.g. corn flakes), white rice and potatoes.
