    Once Weekly versus E3D injections


    Obviously if you're doing well on once weekly, you wouldn't want to poke more holes in your body than you have to.

    But what's the difference/reasoning for doing E3D?

    If the half life of cyp is around 10 days, what would be the point of injecting more frequently? I can't understand why it would make a difference but understand it does for some.

    And yes, serum T levels would be more stable, but they'd also be more stable if you injected every day. Is it a metabolite (i.e. less E2) issue?

    From what I've read, it's an e2 thing as well as keeping everything stable. You could probably poke ed using test prop, but that would be no fun :P I think you invite less sides that come along with fluctuating hormone levels as well when things run more stable (acne, etc). Blood tests are likely more accurate this way too.

    The half-life of test cyp is less than 10 days... i've read comments from several doctors including Dr. C that the half-life for cyp is closer to 7-8 days and Fizer (who produces Depo-Testosterone for TRT) claims a half-life of ~8 days.

    Assuming that this is true versus what is circulating on BB boards regarding half-lives, injecting once a week is not optimal. Injecting at half the half-life (or twice a week) would give you relatively stable levels with minimal pokes.

    Yes they would be most stable if injected ED but we have to find a balance of optimal bloodlevels with number of pokes. That said, it will still work if you injected only once a week or even once every two weeks but again... it's about finding balance.

    Yes, also seen half-life of about 8 days for test cypionate in production information sheets from pharmaceutical companies.

    I personally inject every 5 days 100mg.

    says

    Testosterone cypionate 6 days
    Testosterone entantate 5 days

    100mg/5days=100/5*7=140mg/weekly on average
