I really can't see one to be honest. It's just the game we play.
Unless like I probably said prior - one time I was pinning 500mg and came out not even high TRT numbers. Under 1000. I was pissed. That is blatantly under dosed.
Here's my 2c. I'm pretty conservative on the matter. I think most figures are grossly overstated anecdotally as 'typical'. Say 200mg TRT is high normal (or usually a little over), so call that 1,200 even.
Running 1ml 250mg a week should get you 1,500 on average. Therefore on 'cycle' running anything over that, I would call anything above 2,000 fair game personally. And if someone claims you can't build muscle on 2,000 or that running 300mg a week or whatever is 'a waste', then they have rocks in their head and sand in their vajin.
If I dealt/supplied, there would be no way in hell I'd be refunding someone who was over 2,000 on a cycle dose. Again, I'm conservative. The numbers I've seen over the years (collectively, not on me) even with pharma gear have been in the typical expected range of 3,000 - 4,400 running 500 - 750mg. Realistic doses. If you're over 3,500 running any decent dose there is absolutely zero fucking wrong with your gear. Zero. If you're not a monster at 3,500, cancel your gym membership because weight lifting isn't for you.
The guys I know - I'm talking real obsessive pro's going for the big world prize - have to run at least a gram or more to see anything past the 4,500 mark. And that's just retarded anyway. Who can even stand the blood pressure sides, etc? No-one.
