In today's EliteFitness.com News, my friend Eric Potratz will show you in his article HCG - Human Chorionic Gonadotropin Use After Anabolic Steroid Cycles for Bodybuilding <\/strong>the most effective way to recover from an anabolic steroid cycle. This is especially the case for those that have had a lack of success following popular advice. In his article, Eric will address the misunderstanding and misuse of Human Chorionic Gonadotropin (hCG) and will show you the most efficient way to use hCG for the fastest and most complete recovery.<\/p>\n

Post Cycle Therapy or PCT for short is a must after you have finished a steroid cycle. If you want to keep the strength and muscle gains you worked so hard for when you were on the juice, you need to help return your own body's hormonal levels back to normal - or all you hard work will be wasted. Many great PCT protocols have been outlined over the years, and many individuals have had success following them. Nevertheless, what works can always work better.

HCG - Human Chorionic Gonadotropin Use After Anabolic Steroid Cycles for Bodybuilding <\/strong><\/p>\n

Human Chorionic Gonadotropin (hCG) is a peptide hormone that mimics the action of luteinizing hormone (LH). LH is the hormone that stimulates the testes to produce testosterone. (1) More specifically LH is the primary signal sent from the pituitary to the testes, which stimulates the leydig cells within the testes to produce testosterone.<\/p>\n

When steroids are administered, LH levels rapidly decline. The absence of an LH signal from the pituitary causes the testes to stop producing testosterone, which causes rapid onset of testicular degeneration. The testicular degeneration begins with a reduction of leydig cell volume, and is then followed by rapid reductions in intra-testicular testosterone (ITT), peroxisomes, and Insulin-like factor 3 (INSL3) \u2013 All important bio-markers and factors for proper testicular function and testosterone production. (2-6,19) However, this degeneration can be prevented by a small maintenance dose of hCG ran throughout the cycle. Unfortunately, most steroid users have been engrained to believe that hCG should be used after a cycle, during PCT. Upon reviewing the science and basic endocrinology you will see that a faster and more complete recovery is possible if hCG is ran during a cycle.<\/p>\n\n\n\n

Firstly, we must understand the clinical history of hCG to understand its purpose and its most efficient application. Many popular \u201csteroid profiles\u201d advocate using hCG at a dose of 2500-5000iu once or twice a week. These were the kind of dosages used in the historical (1960\u2019s) hCG studies for hypogonadal men who had reduced testicular sensitivity due to prolonged LH deficiency. (21,22) A prolonged LH deficiency causes the testes to desensitize, requiring a higher hCG dose for ample stimulation. In men with normal LH levels and normal testicular sensitivity, the maximum increase of testosterone is seen from a dose of only 250iu, with minimal increases obtained from 500iu or even 5000iu. (2,11) (It appears the testes maximum secretion of testosterone is about 140% above their normal capacity.) (12-18) If you have allowed your testes to desensitize over the length of a typical steroid cycle, (8-16 weeks) then you would require a higher dose to elicit a response in an attempt to restore normal testicular size and function \u2013 but there is cost to this, and a high probability that you won\u2019t regain full testicular function.<\/p>\n

One term that is critical to understand is testosterone secretion capacity which is synonymous to testicular sensitivity. This is the amount of testosterone your testes can produce from any given LH or hCG stimulation. Therefore, if you have reduced testosterone secretion capacity (reduced testicular sensitivity), it will take more LH or hCG stimulation to produce the same result as if you had normal testosterone secretion capacity. If you reduce your testosterone secretion capacity too much, then no amount of LH or hCG stimulation will trigger normal testosterone production \u2013 and this leads to permanently reduced testosterone production.<\/p>\n

To get an idea of how quickly you can reduce your testosterone secretion capacity from your average steroid cycle, consider this: LH levels are rapidly decreased by the 2nd day of steroid administration. (2,9,10) By shutting down the LH signal and allowing the testis to be non-functional over a 12-16 week period, leydig cell volume decreases 90%, ITT decreases 94%, INSL3 decreases 95%, while the capacity to secrete testosterone decreases as much as 98%. (2-6)<\/p>\n

Note: visually analyzing testes size is a poor method of judging your actual testicular function, since testicular size is not directly related to the ability to secrete testosterone. (4) This is because the leydig cells, which are the primary sites of testosterone secretion, only make up about 10% of the total testicular volume. Therefore, when the testes may only appear 5-10% smaller, the testes ability to secrete testosterone upon LH or hCG stimulation can actually be significantly reduced to 98% of their normal production. (3-5) The point here is to not judge testosterone secretion capacity by testicular size.
\n\"HCG\"<\/p>\n

The decreased testosterone secretion capacity caused by steroid use was well demonstrated in a study on power athletes who used steroids for 16 weeks, and were then administered 4500iu hCG post cycle. It was found that the steroid users were about 20 times less responsive to hCG, when compared to normal men who did not use steroids. (8) In other words, their testosterone secretion capacity was dramatically reduced because they did not receive an LH signal for 16 weeks. The testes essentially became desensitized and crippled. Case studies with steroid using patients show that aggressive long-term treatment with hCG at dosages as high as 10,000iu E3D for 12 weeks were unable to return full testicular size. (7) Another study with men using low dose steroids for 6 weeks showed unsuccessful return of Insulin-like factor-3 (INSL3) concentration in the testes upon 5000iu\/wk of HCG treatment for 12 weeks (6) (INSL3 is an important biomarker for testosterone production potential and sperm production. 20)<\/p>\n

These studies show that postponing hCG usage until the end of a steroid cycle increases your need for a higher dose of hCG, and decreases your odds of a full recovery. As a consequence to using a higher dose of hCG at the end of a cycle, estrogen will be increased disproportionately to testosterone, which then causes further HPTA suppression (from high estrogen) while increasing the risk of gyno. (11) For example, high doses of hCG have been found to raise estradiol up to 165%, while only raising testosterone 140%. (11) Higher doses of hCG are also known to reduce LH receptor concentration and degrade the enzymes responsible for testosterone synthesis within the testes (12,13,19 ) -- the last thing someone wants during recovery. While these negative effects of hCG can be partly mitigated by the use of a SERM such as tamoxifen, it will create further problems associated with using a toxic SERM (covered in another article).<\/p>\n

In light of the above evidence, it becomes obvious that we must take preventative measures to avoid this testicular degeneration. We must protect our testicular sensitivity. Besides, with hCG being so readily available, and such a painless shot, it makes you wonder why anyone wouldn\u2019t use it on cycle.<\/p>\n

Based on studies with normal men using steroids, 100iu HCG administered everyday was enough to preserve full testicular function and ITT levels, without causing desensitization typically associated with higher doses of hCG. (2) It is important that low-dose hCG is started before testicular sensitivity is reduced, which appears to rapidly manifest within the first 2-3 weeks of steroid use. Also, it\u2019s important to discontinue the hCG before you start PCT so your leydig cells are given a chance to re-sensitize to your body\u2019s own LH production. (To help further enhance testicular sensitivity, the dietary supplement Toco-8 may be used)<\/p>\n

A more convenient alternative to the above recommendation would be a twice a week shot of 200iu hCG, or possibly a once a week shot of 500iu. However, it is most desirable to adhere to a lower more frequent dose of hCG to mimic the body\u2019s natural LH release and minimize estrogen conversion. If you are starting hCG late in the cycle, one could calculate a rough estimate for their required hCG \u2018kick starting\u2019 dosage by multiplying 40iu x days of LH absence, since the testes will be desensitized, thus requiring a higher dose. (ie. 40iu x 60 days = 2400iu HCG dose)<\/p>\n\n\n\n
