hCG
The majority of anabolic steroid users from the 1960s–mid 1980s did not even utilize any compounds for the purpose of hormonal recovery, and the term PCT did not even exist at that time. When the use of hCG became increasingly popular (circa 1980), it was the only compound utilized. Since then, the medical and scientific understanding of such things has increased exponentially and there should be no reason for any informed and properly educated individual to utilize hCG on its own for PCT. When utilized in conjunction with one of the other two categories of compounds (an AI and a SERM), the dynamics change considerably.
hCG mimics LH and therefore actually keeps the testicles producing testosterone even when anabolic steroids are present. However, it does not induce the production of actual LH. The use of hCG on cycle, this is primarily done so that post-cycle recovery is easier. hCG is also used on cycle to prevent or at least minimize testicular atrophy that occurs due to the use of anabolic steroids. The testicular atrophy that occurs is not permanent, but will reverse once steroid use is discontinued and natural testosterone production begins again.
It has been mentioned already that much of the difficulty in recovering the HPTA following an anabolic steroid cycle is the result of Leydig cell desensitization. hCG is essentially an analogue of LH, and the testes after a prolonged anabolic steroid cycle would be as equally desensitized to hCG as they are to LH. The human body, however, produces LH amounts on its own that are far too inefficient for proper and rapid Testosterone production.
The body’s natural increase of LH and FSH following an anabolic steroid cycle is also not a rapid peak, but a very slow and steady incline, as evidenced by the study referenced earlier in which it was not until 3 weeks when LH levels only began to reach the normal physiological measurements following the cessation of exogenous Testosterone. Therefore, the body’s own natural LH production does not provide a high enough dose for stimulation, nor an immediate stimulation to the testes required for the initial increase in Testosterone needed during the post cycle therapy weeks.
We will be utilizing a SERM which will stimulate FSH/LH, but most will find recovery being a smother transition when hCG is utilized. Studies have in fact demonstrated the incredible effectiveness of hCG for this purpose, and it is even suggested clinically that hCG be utilized for the purpose of treating anabolic steroid induced hypogonadism.\4])
If you choose to include hCG in your PCT protocol, the best possible SERM for the PCT protocol is Nolvadex, as studies have demonstrated that hCG and Nolvadex utilized together have exhibited a remarkable synergistic effect in terms of stimulating endogenous Testosterone production, and that Nolvadex will actually work to block the desensitization effect on the Leydig cells of the testes caused by high doses of hCG .10
HCG is ran a couple different ways:
- Over The Entire Cycle
- Weeks Leading Up To PCT
- 1-2 Weeks Before PCT
- First 1-2 Weeks Of PCT
1. Over The Entire Cycle
This is the preferred option, as it keeps the Leydig cells active, reducing atrophy and the reactive oxygen species (ROS) free radical damage incurred by prolonged shutdown. HCG can be ran over the entire length of the cycle to make PCT easy and efficient, if desired:
- Over Entire Length Of Cycle: 250 IU EOD
- Stop HCG use before starting PCT (SERM)
Important Note: 250 IU 2x/week is used by some, but there have been studies on maintaining intra-testicular testosterone in healthy men with gonadotropin suppression. This study found 125 IU EOD (437.5 iu/week) was 25% less than baseline. Alternatively, 250 IU EOD (875 iu/week) was found to only be 7% below baseline.13
For this reason,
it is recommended to use 250 IU EOD. If desiring to be as close to baseline as possible, you would need more than 875 IU/week (7% less than baseline) and less than 1750 IU/week (26% above baseline). This is where the 500 IU 2x/week comes in, but without a study comparing, we are only speculating and you could need more. Alternatively, if money is a factor, it is best to use some hCG rather than no hCG, and you may do less than the recommended: 500-750 IU/week.
If only taking it for PCT, and not regularly:
2. Weeks Leading Up To PCT
This is the preferred method after Option 1, especially for those that are coming off a long cycle or blast and cruise.
Starting 6 weeks before PCT:
- Weeks 6-4: 500-1000 IU 3x/week
- Weeks 3-1: 250-500 IU 3x/week
- Week 0: Start PCT (SERM)
3. 1-2 Weeks Before PCT
Typically this will be run in the ~2 weeks leading up to PCT after your last injection, while you are waiting for your AAS esters to clear (assuming long esters such as Test E or C). If using short esters (Prop and/or Ace), nothing changes. You just start the HCG while on cycle (1-2 weeks before PCT).
If you chose to utilize hCG in this fashion (unless using short esters (Prop and/or Ace), there is one remaining issues to be addressed:
- The fact that hCG causes increased production of aromatase, leading to increased Estrogen levels. See Below
This is where the AI is to be utilized as a supportive compound for hCG use in this 1–2 week period, and after hCG is discontinued early on in PCT, only the SERM to be used in order to carry along the hormonal recovery process. hCG utilized in this fashion will be ran:
- 1-2 Weeks Before PCT: 1000-1500 IU EOD
- 1-2 Weeks Before PCT: AI will be used only as long as HCG
4. First 1-2 Weeks Of PCT
Some will say hCG shouldn't be ran into PCT as it's suppressive, but as noted above in the study with Nolvadex, it has shown to be effective when run simultaneously with Nolvadex.10
If you chose to utilize hCG in this fashion, there is one remaining issue to be addressed:
- The fact that hCG causes increased production of aromatase, leading to increased Estrogen levels. See Below
This is where the AI is to be utilized as a supportive compound for hCG use in this 1–2 week period, and after hCG is discontinued early on in PCT, only the SERM to be used in order to carry along the hormonal recovery process. hCG utilized in this fashion will be run as follows:
- First 1-2 Weeks Of PCT: 1000-1500 IU EOD
- First 1-2 Weeks Of PCT: AI will be used only as long as HCG
