That's extremely pricey, you shouldn't be paying more than about $100, these clinics are expensive! Curious what your peaks and troughs are with that huge T dosage, not many can even handle 200mg weekly. You could have them give you the prescription and go fill it where you want.
I really don't notice the low points given that by day 7 I'm still a little above 50% the original dose. Honestly I feel great all the time now and I've dropped from 22% body fat to 14%, sex is much improved and working out more. Only thing for me is I really have to stay on top of my estrodol, it tends to go up very quickly. If I don't take my estrogen blocker correctly it gets out of control and I start seeing very noticeable high estrogen symptoms.
If you lift heavy and by that I mean a classic strength training program with the big compound lifts of Bench, Incline Bench, Shoulder Press, Rows, Squats, and Deadlifts, you would gain a significant amount of muscle mass with 300 mg of test cyp a week. That is above a therapeutic dose and almost to the level of a body builders cycle. If I was paying that kind of money for it, I would definitely be trying to maximize the benefits of it.
That all said, you really shouldn't be on that much testosterone long term. 200 mg of test a week is typically the upper limit for that. Moreover, you are definitely paying too much. Find a good GP that will treat you so you are not paying so much out of pocket.
If you have a traditional PPO, a month's worth of testosterone cyp at 200 mg of test a week, will cost you the 10 dollar copay for a prescription at the pharmacy. If you have a high deductible health plan where you are paying for your prescriptions out of pocket, a month's worth of testosterone will cost you as little as $37.50 with a WellRx coupon.
Even if you have a high deductible plan where you are paying everything out of pocket for your treatments until you hit your deductible, its not that expensive if you find a good GP that is experienced with TRT. Basically, every year you would looking at a total of:
$250 or so for doctors visits
$200 or so for labwork
$325 or so for testosterone
$20 dollars or so for syringes (you can order these from a supply online)
