First off nolvadex is the worst pct ever after a deca cycle my friend. Nolva upregulates the progesterone receptors as well as reacts with prolactin/progesterone to cause all kinds of problems.
After a cycle of deca one of the most commonly forgotten aspects of the pct is bringing progesterone/prolactin levels back to normal stable levels. The point of pct is to normalize all of the bodies hormone cascade and these hormones are very much a part of that... This is often why deca,tren,npp, aka nandro/progestrin cycles are mislabeled as "harder to recover from" When in fact the problem is not that they are harder to recover from they just require a different recovery..
Some people will argue the fact that deca is harder to recover from because it stays in the system for a long time but then what about npp,tren-ace, methyl methoxy, and other progestrins? They have much shorter half lifes yet still have been Mislabeled in the same manner...
What can compound this problem is the fact that people never take into consideration that HCG can also have effects on the PR as well. Failing to run Hcg during the cycle and running it after and during the pct is a huge mistake.
It just so happens I have a sust/deca cycle lay out in my note pad files here. Let me dig it out for you... Ok starting out we are going to run the hcg during the cycle and not after. If you already started the cycle no worries just start the hcg now and run it through out the rest of the cycle along with the other drugs and supplements I lay out for you... Another thing you want to do is push your sust to 12 weeks. Giving you 2 weeks past the deca. This allows ample time for the deca to clear the system and keeps it in line with around the time your sust will be clearing.
Now I am going to assume you are fairly new to this kind of a cycle so my doses of the drugs and supplements will be based off of this. If you are at higher doses of the sust and or deca then so be it but the lay out and general concept of the cycle remains the same.
The cycle will be as follows
weeks
1-12 sust 250mg twice a week monday and thursday
1-10 deca 300mg once a week
1-12 hcg 500ius twice a week
12-16 hcgenerate 3 caps am 2 caps pm
12-16 forma-stanzol 5 pumps am and pm
12-16 (optional) clomid 25mg ed
Keep letro and dostinex on hand for sides. no need to use them unless you get sides however do not be a fool and run a cycle like this without having them on hand.
The forma-stanzol had a drug called letheron in it that lowers estrogen and progesterone. Its known as a suicide aromatase inhibitor. Along with that it has natural phytoserms
that work like clomid and nolva but naturally and les harsh... By using a product like this you can get away with using a lot less ( or non at all your choice) clomid or nolva during pct. With higher dosing comes most of the side effects that these drugs are known to cause. You can read more about forma-stanzol here in this thread.

Or from rxprohub.com and even superiorshippers.com works..
Check out the elite-bodiez.com forum for good source info or drugsprofiles.com has a lot of good info for ya too..
This is just a basic outlay of a cycle and pct. Many things can be added to help with different results. Added effects for pct like lost nutrition retention can be addressed by using products like Need2slin and or gear. Post pct supplements like Bridge can also help to retain more gains after pct is over. More of a extended pct or even used as a bridge ( HMM guess that is why its called bridge lol)...
Sarms is another great drug to use as ether a pre pct or a mini cycle between cycles however it has been and always will be my stance that sarms should never be taken during the actual pct. Although much literature shows they are mildly to non suppressive depending on dosing. They still do not allow for complete recovery of the entire hormone cascade. Taking more hormones is not how you get your hormone levels to recovery back to normal...
I would read this thread rigth here my friend. Its chock full of massive amounts of steroid info.. So much it will make your head spin.

A adjusted my post for you a bit ^^^. Keep in mind I been doing this for well over 7 years on many different forums. I am the eaxt elite mod of this site for a good reason and its not because I
sell supplements. I was the ext elite mod here long before I owned a sup company ( or 4 lol). The advice of give is taken by thousands every month and all it takes is one look around the forums to see
that everyone has enjoyed that advice and have always gained.learned from it.
You can send me a pm any time with any extra questions you may have.

Why hcg during the cycle and not after.
Post-Cycle-Therapy is a must upon cessation of steroid use. Many great Post Cycle Therapy protocols have been outlined over the years, and many individuals have had success with following such protocols. Nevertheless, what works can always work better, and I intend to show you the most effective way to recover from AAS. This is especially the case for those that have had a lack of success following popular advice. In this article I will address the misunderstanding and misuse of Human Chorionic Gonadotropin (hCG) and show you the most efficient way to use hCG for the fastest and most complete recovery.
HCG unraveled -
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 increase testosterone levels. (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.
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) - 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 Post-Cycle-Therapy. 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.
Firstly, we must understand the clinical history of hCG to understand its purpose and its most efficient application. Many popular “steroid profiles” 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's) 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 - but there is cost to this, and a high probability that you won't regain full testicular function.
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 level of 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 natural testosterone production - and this leads to permanently reduced testosterone production. (recovering full testosterone production is a topic for another article)
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)
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) So do not judge how "shutdown" you are by testicular size!
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
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't use it on cycle.
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's important to discontinue the hCG before you start Post-Cycle-Therapy so your leydig cells are given a chance to re-sensitize to your body's own LH production. (To help further enhance testicular sensitivity, the dietary supplement Toco-8 may be used)
Based off the above information, an optimal dose of hCG during the cycle would be 250iu every 4 days, or as a less desirable alternative, once a week shot of 500iu. Keep in mind, that the half-life of hCG is 3-4 days, while the half-life of LH is only 1-2 hours. Considering this difference in excretion time, it is best to space each dose of hCG at least 4 days apart for the optimal "peak and valley" replication. However, going more than 7 days between each hCG shot may promote increase the rate of desensitization from lack of LH or hCG stimulation.
If you are starting hCG late in the cycle, one could calculate a rough estimate for their required hCG "kick starting" dosage by multiplying 40iu x days of LH absence. (ie. 40iu x 60 days = 2400iu HCG dose) Remember, since the testes will be desensitized later in a cycle, you will require a higher dose. Also, the maximum daily dose of hCG should not exceed 5000iu, and 4-7 days must be taken off between each shot. Generally, a higher dose will require a longer off period between each shot. (eg., 2500iu = 7 days between each shot)
Note: If following the on cycle hCG protocol, hCG should NOT be used for PCT.
Recap -
For preservation of testicular sensitivity, use 250iu every 4 day starting 14 days after your first AAS dose. At the end of the cycle, drop the hCG two weeks before the AAS clear the system. For example, you would drop hCG about the same time as your last Testosterone Enanthate shot. Or, if you are ending the cycle with orals, you would drop the hCG about 10 days before your last oral dose. This will allow for a sudden and even clearance in hormone levels. This will initiate a strong LH and FSH surge from the pituitary, to begin stimulating your testes to produce testosterone. Remember, recovery doesn't begin until you are off hCG since your body will not release its own LH until the hCG has cleared the system.
In conclusion, we have learned that utilizing hCG during a steroid cycle will significantly prevent testicular degeneration. This helps create a seamless transition from “on cycle” to “off cycle” thus avoiding the post cycle crash.

Just tossing out references for my explanations now lol... But any time you or anyone wants to ask me "why" about anything I welcome these questions and enjoy explaining things to people. SO again feel free to ask anything.

I don't get it though, I've read on a lot of sites not to run hcg for longer then 6 weeks but what if I'm on a 20 week cycle. Thank you for the information on hcg I haven't read a article or thread as detailed on it.
