Difference in gear strength

[CheckFire]

Other than the obvious, what's the difference between two vials of something where one has almost twice as much in it? For example, what's the difference between 100 mg per ml of tren ace versus 300 mg per ML? Is there more PIP, a faster or slower rate of absorption?

 

[Jbranken]

The rate it is metabolized is only dependent upon the ester, not the mg/ml

More pip is definitely possible. UG labs also like to underdose their gear and make rediculous claims of higher potency gear so they can stick a bigger price tag on it
