Yeah I use these guys all the time. Have been using them to track bloods whilst on cycle. Usually takes 1-2 weeks to get the pack, prick your finger then send it back (paid for). They receive it the next day and results are usually released in 3-4 days.
Expensive but its awesome. And anonymous.
Start?
You should be doing this year round till you figure out your needs. On & off cycle. You need to learn how to eat. Honestly I know people are recommending Funnyman a lot but there is a reason for this - it works. Have you reached out to him? Rather then spending money on gear which is not needed FM will actually be able to help you shed all the weight.
You need to use Funnyman.
The money you were going to spend on gear should just be directed his way. Then when he gets you in good shape you can look at cycling further down the line.
I'd recommend going with at least 400mg/week test. I'm currently on first cycle and considered going lower; in the end I'm glad I went with the "standard" 500/week. It's pretty mild and I would have been disappointed with a lower dose I think.
Advice I was given and the advice I would give would be not to use an AI unless you have to. Had I gone off all these cookie cutter first cycles my estrogen would be well in the shitter right now - I'm on week 7 and haven't used an AI yet (I also wasn't a fat bastard at the start of the cycle).
I think the most important thing is you AT LEAST get pre cycle bloods so you know you're baseline.
