Tongkat Ali 2% Capsules are also available.


Our tongkat ali powder is standardized to 2% Eurycomanone, which is the main active ingredient in this supplement. Most companies advertise different extract ratios of longjack powder; however, these ratios mean little without the active compound Eurycomanone. We are the only retailer that performed this testing to guarantee the amount of Eurycomanone present in our powder.

Curated Reviews

"I've had a long relationship with Tongkat. I used to buy from a supplier in Canada - best quality I've ever had, but super expensive. So I tried finding my own source, which led to a lot of frustration. 100:1 or 200:1 is meaningless. It just means they start off with, say, 100 times more plant material than they end up with in the final extract product. It doesn't speak to the strength of the source material, the process used, etc. Additionally, it is my understanding that Tongkat has to be kept from air and heat. So I had trouble finding something that came close to the super-bitter stuff I got from my source in Canada. I kept asking myself - "Why can't they standardize this stuff?". Finally, Powder City has come through with the holy grail - a standardized Tongkat. It's pretty bitter, and that's a good indication of potency. A good dose for me is a heaping .5cc (1/2 cc) scoopful. I combine with Horny Goat Weed extract, and Powder City has a good one for that, too. Remember you can't take it constantly - some say 5 days on/2 days off, and some say 2 weeks on/one week off. General recommendation seems to be somewhere between 33% and 40% off cycle time. I don't know what happens if you don't respect the off cycle time, I just have always respected it. – David S.

"Used 10 grams of this so far, what I can say is that this is not like other herbs that are subtle in nature, you can DEFINITELY feel this working. Raise in mood, motivation and a substantial increase in aggression. Not that it makes you on edge, quite the opposite you are in a good mood, but if someone crosses your path... lets say you are quick to respond. Must take days off, but used sparingly, one of the most effective supplements I've used, and definitely one of the strongest.– Daniel B.
