I'm sorry... it's easy to say to a novice that in a week or two you're going to be a big strongman and ripped freak but anyone who has been taking AAS for any amount of time knows it takes about 4 weeks to accumulate peak absorption into ones system. Slightly less with faster esthers. By this analogy you could be at your peak an hour after you pin.. but we know that's not the case.
You may respect someone's opinion in saying that after 2 weeks their fucking phenomenal... but I don't. I have used most popular compounds and esthers, and I know what the difference looks and feels like. There's no comparison between week 2 and week 4. Except for orals.

The normal progression of blood level buildup is as follows (using Testosterone Enanthate as the example compound, for the purpose of explanation, its half-life will be regarded as 7 days):
Day 1: 500mg
Day 7: 250mg remaining from the previous injection + 500mg freshly injected = 750mg total
Day 14: 375mg remaining from the previous injection + 500mg freshly injected = 875mg total
Day 28: 437.5mg remaining from the previous injection + 500mg freshly injected = 937.5mg total
Day 35: 468.75mg remaining from the previous injection + 500mg freshly injected = 968.75mg total
Day 42: 484.38mg remaining from the previous injection + 500mg freshly injected = 984.38mg total
