No flame JC but I don't know where this idea about it taking 4-5 weeks for deca or eq to "kick in" comes from. Maybe some people aren't noticing results for that long (I'm not in that group), but it certainly does not take that long for either drug to begin working, especially if they are front loaded.
I will concede that because they are long ester drugs a single shot of say 400 mgs. isn't likely to do much because the ester releases the active ingredient over a long time. If you aren't shooting that much per week, it takes some time to build up enough esterfied gear for the blood levels of deestrified gear to get high, but 4-5 weeks! I think not.
I don't think you are going to tell me that if my normal dose of eq is 400 mgs. per week, and I inject 1200 mgs. in the first week and then 400 mgs. in each successive week, that it is still going to take 5 weeks before the drug become effective, right? Its all about how much destrified eq is in my blood at any given time, correct?
As far as combining the two, I've done it and it works just fine. The main reason I have done it this way is because deca relieves my joint pain even at relatively low doses, which I get harder and more vascular on eq. I want both benefits, so I'll use them together.
