Yes, we already know that the half life of testosterone propionate is 2 to 3 days. We get it. I get it. Understood. I get all of that. But honestly speaking..... From the time 1cc of testosterone propionate (100mgs)is injected, for how many hours will I actually be able to feel it's effects? It's most certainly not for 48 hour plus, that's for sure. Realistically speaking.... Is it active for 12 hours? 18 hours? Really..... 24 hours?!
