      Frontloading Basics and Dosages

      by Curls4dGirls at SuperiorMuscle.com with contributions by Skyefire and Spidey



      The purpose of this thread is to provide some basic information on frontloading, including an explanation of half-lives, differences across esters, and recommended frontloading dosages.

      HALF-LIFE BASICS

      Each compound includes an ester that, along with other factors, controls the release of the hormone into the system. The rate of release differs by ester and is defined in terms of half-life. The average half-lives of esters are:

      ESTER HALF LIFE (days)
      Formate 1.5
      Acetate 3
      Propionate 4.5
      Butyrate 6
      Valerate 7.5
      Hexanoate 9
      Caproate 9
      Isocaproate 9
      Heptanoate 10.5
      Enanthate 10.5
      Octanoate 12
      Cypionate 12
      Nonanoate 13.5
      Decanoate 15
      Undecanoate 16.5

      The half-life is the length of time (in days) to release half of the hormone into the system. For example, if 500 mgs of Testosterone Cypionate is administered, in 12 days, on average, 250 mgs of testosterone has been released into the system and 250 mgs of testosterone remains attached to the ester. In another 12 days, an additional 125 mgs (half of the remaining 250 mgs) has been released into the system for a total of 375 mgs released and 125 mgs still attached to the ester. The key detail is that different esters release the hormone into the system at different rates. Therefore, different esters require different frontload dosages.

      FRONTLOADING

      The purpose of frontloading is to quickly reach the target dosage to more quickly realize the benefits of the AAS. This thread provides instructions to reach 75% of the weekly dosage within the first week

      Most people use, as a rule of thumb, twice the weekly dosage (double dosing) in the first week. That works well for esters with a half-life of 10.5 days or less. However, this does not work well for longer esters. Let’s look at EQ as an example. If the intended weekly dosage is 600 mgs, then the frontload dosage, based on double dosing, is 1200 mgs. Although 50% of the intended dosage is reached in the first week, 75% of the intended dosage is not reached until week 4. Without any frontloading, 75% of the intended dosage is reached in week 5. So, while ‘double dosing’ works, the effects diminish with increasing half-life.

      EQ Double Dose Values at 600 mgs (1200 mgs in Week 1)

      No Frontload
      Released… % of Target
      Week 1 153… 25%
      Week 2 267… 44%
      Week 3 352… 59%
      Week 4 415… 69%
      Week 5 462… 77%
      Week 6 497… 83%

      Double Dosing
      Released… % of Target
      Week 1 306… 51%
      Week 2 381… 63%
      Week 3 437… 73%
      Week 4 478… 80%
      Week 5 509… 85%
      Week 6 532… 89%



      The following table includes frontloading dosage to reach 75% of the intended dosage by the end of the first week. The dosages are indexed at 100 mgs / week. To reach your intended dosage, simply multiply the frontload dosage by your weekly dosage divided by 100. For example, if you wanted to run Testosterone Cypionate at 800 mgs / wk, then multiply the frontload dosage of 225 mgs by 8 (800 / 100) for 1800 mgs in week 1.

      ESTER FRONTLOAD DOSAGE(mgs)
      Formate 100
      Acetate 100
      Propionate 115
      Butyrate 130
      Valerate 160
      Hexanoate 180
      Caproate 180
      Isocaproate 180
      Heptanoate 200
      Enanthate 200
      Octanoate 225
      Cypionate 225
      Nonanoate 250
      Decanoate 270
      Undecanoate 295


      The calculation used is M*** = MgD * (1/2)^(D/HL), where:

      M*** = Mgs of depot left
      MgD = Mgs in depot (total)
      D = Days
      H = Half-life

      Injections for Formate and Acetate are daily. Injections for Propianate are every other day. Injections for Butyrate are every 3 days. All other esters are administered as one injection at the beginning of the week 1. It should be noted that injection frequency does not significantly influence frontloading dosages.

      good info. I'm not sure if I agree with "frontloading" in this respect, but good read and helpful information. I don't think you can generalize frontloading.

      Great read! This really would be a great sticky! I have my own opinions about front loading but everyone should know about half lives.
