This is to be taken everyday preferably at night on an empty stomach. I personally wouldn't purchase this because to it wouldn't last long enough to see any kind of results at all. It's only 16 IU's, the average intermediate/experienced user of HGH takes at the lowest 3-4 IU's a day, more advanced users hover around the 8-10 IU a day mark (I'm not advanced with HGH and to be honest I've never taken HGH ever before because in order to even begin to start noticing just even the smallest of positive effects is the 3-6 month mark (I have several very close friends of mine who are experienced at using HGH and the lowest amnt per day my best friend takes is 8 IU a day, therefore this pen would last him 2 days). Lucky for him he was a trust fund baby and recently lost his Mom and Dad and had tens of millions in liquid assets left to him alone with 3 very nice houses (his Pops owned 2 half mansions fully paid off and his Mom owned a very nice home maybe an 1/8th of a mansion also fully paid off so he sold all 3 and made another 10 million off that),so what I'm getting at is if you're going to experiment or use HGH you either need to be damn near a millionaire like my best friend in order to afford it enough to make it worth ur time, or save up and every month try to put $300-$500 away for 8-12 months and then once you have about $6,000 put away then put that towards the best bulk deal of HGH you can find and you depending on how many IU's you plan to pin daily will decide whether you can squeeze possibly up to a yr of a decent daily amnt that'd make it worth it for you enough to see some results, and if u want drastic results you should also be stacking a good cycle of anabolics where you can do a good 12-16 week cycle while starting the HGH at the same time. Make sure Test is your base of that cycle regardless of what your goals are, And depending on your goal will depend on how many other compounds you can/should stack with this and id reach out to the professionals on here and tell them how much $$ u have to work with and from there ask them if they can put together a 16 week cycle for you to see what compounds you can stack on your cycle, take 6-8 weeks off and do a VERY PROPER NO SHORT CUTS PCT, and once uve done that then hop on another cycle (all the meanwhile even during your PCT and time off your cycle you'll still be pinning your HGH daily), this will make it to where after 1 yr of this you're going to see such dramatic results (depending on genetics) that you're likely to look like an entire different person for the better. Trust me if I had even a penny to put aside for a year's worth of daily HGH (or a tad bit lower daily dose for everyday use for life) along with the 4 good length cycles I do per yr which I'm not even financially able to truly afford the best stacks I could be doing, but if money was no issue then this is the amounts of money you should be prepared to spend to see maximum results.

Do you take this every day and how many days does this pen last?
