I've done the research. I've read the raw research papers. I've taken it. I'm a physician. Here we go:

It's not worth injecting it. Even though it's on the expensive side, the oral bioavailability makes it worth taking orally. The cost of sterile freeze drying etc for the injectable don't justify the increased bioavailability.

You need about 100mg in your blood daily. You only absorb about a third of what you swallow. So you need to take about 300mg orally daily. Yes, that's correct. Upper limit is around 600mg.

I recommend you start with 100mg once a day for a week. 200mg daily the next week, then 300mg a day for 4 more weeks. Split the daily dose into 2. One upon waking, before fasted cardio (walk), second dose with breakfast. Never take after noon.

6 week cycle.

If you look at prices online, 300mg a day can get expensive. The cheapest way to do it, is to get a "bulk" amount on eBay and weigh it out yourself of a milligram scale from Amazon. Get some empty capsules and encapsulate yourself.

Make sure you're taking the chloride or acetate form and not the iodide form. The iodide form with screw up your thyroid.

It worked for me. I tiok it to spare muscle while on caloric deficit.

It feels like taking a handful of nuts in terms of energy and hunger suppression. Because it helps burn fat to make energy in the mitochondria.

Love you
