What are anti-estrogens?
In simple terms Anti-estogens block or reduce levels of estrogens in the body. For the purposes of TRT you should have an anti-estrogen product on hand should you ever feel estrogenic side effects occuring such as nipple tinderness, puffy skin, weight gain etc which can occur if you are taking too much testosterone. If excess testosterone is detected in your system your body automatically converts some of it to estrogen in an effort to balance out your hormones and by doing so can cause irriversable side effects such as breast tissue growth in males. It is for reasons like this it is necessary to have some form of protection available should it be needed which is often immediately to prevent side effects from getting worse. Taking anti-estrogens on their own has the effect of boosting natural testosterone levels and reducing or near eliminating estrogen in the system. As you know, estrogen is a female hormone and too high of levels cause undesirable effects such as weight gain, tiredness, puffy skin, water retention etc.

SERM'S (Selective estrogen receptor modulators)

Selective estrogen receptor modulators are suitable for counteracting the side effects you may experience should you use an excessive dosage of Testosterone. TamoX (Tamoxifen) being slightly more suited towards the job. 20mg capsule 3 times daily for 3 days followed by 20mg for 1 week should be sufficient to prevent any side effects should they occur.

ClomiX 

ClomiX by H2 LABS is an non-steroidal Selective Estrogen Receptor Modulator (SERM) product that contains 50 capsules, each dosed at 20mg of Clomiphene Citrate. The active half-life of Clomiphene Citrate is 5-7 days.

Clomid, as it is most often called, is one of the most popular and best PCT drugs available today, and combined with TamoX is a staple of every bodybuilder's protocol for recovery after a cycle. Clomid was origonally prescribed for women to aid in ovulation. In men, the application of Clomid causes an elevation of follicle stimulating hormone and luteinizing hormone. As a result, natural testosterone production is also increased. This effect is obviously beneficial to the athlete, especially at the conclusion of a cycle when endogenous testosterone levels are subnormal. Clomid will gradually raise testosterone levels over its period of intake.
Clomid is also effective as an anti-estrogen on cycle. With the intake of Clomid, the athlete gets the dual effect of blocking out some of the effects of estrogen, while also increasing endogenous testosterone production during PCT.

Users often take the drug in a dosage of 100-150mgs a day for 4-6 weeks following the end of a cycle. Users often combine substances TamoX and HCG to make their PCT plan solid, effective, and guaranteed. ClomiX capsules are around twice the strength of normal dosed Clomid which is usually 10mg which means you are getting twice the strength and twice the value with our capsules!

Clomiphene along with Tamoxifen is a mandatory part of any PCT. Tamoxifen should not be relied upon alone to recover the hypothalamic-pituitary-testicular axis (HPTA). HCG is most especially important to be included also, especially for individuals over the age of 30 where the HPTAxis, natural testosterone and sperm production is harder to recover than in your early twenties.

TamoX

Tamoxifen by H2 LABS is a Selective Estrogen Receptor Modulator (SERM) product that contains 50 capsules, each dosed at 20mg of Tamoxifen Citrate. The active half-life of Tamoxifen Citrate is 7-14 hours.

This product is most often referred to as "Tamoxifen" or "Nolvadex" by bodybuilders. TamoX is not a steroid, rather a selective estrogen blocker. Nolvadex (tamoxifen citrate) is very comparable to Clomid, behaves in the same manner in all tissues, and is a mixed estrogen agonist/antagonist of the same type as Clomid. The two molecules are also very similar in structure. It is not correct that Nolvadex reduces levels of estrogen: rather, it blocks estrogen from estrogen receptors and, in those tissues where it is an antagonist, causes the receptor to do nothing. Nolvadex is not an anabolic steroid but is used to manage side effects from steroids.
Tamoxifen also offers another great benefit to bodybuilders due to the fact that it can greatly increase the amount of testosterone that the body makes by stimulating LH production. This makes the drug a great choice for PCT. TamoX and ClomiX are the two most important parts of P.C.T therapy, along with HCG for successful recovery of the HPTAxis.

The claim that Nolvadex reduces gains should not be taken too seriously. The fact is that any number of bodybuilders have made excellent gains while using Nolvadex. The belief that it reduces gains seems to stem from the fact that the scientific literature reports a slight reduction in IGF-1 (individuals using anabolic steroids were not studied though) from use of Nolvadex. Thus, Dan Duchaine reported that it reduces IGF-1 and therefore reduces gains. However, if this effect exists at all, it must be very minor, due to the excellent gains that many have made, and from the fact that no one has noticed any such thing from Clomid, which has the same activity profile.

Bodybuilders often use Tamoxifen in doses of 20-60mgs a day throughout cycle duration where gyno is a concern. Those looking to incorporate Tamoxifen into their PCT program will typically run the substance at similar doses for 4-6 upon the discontinued use of all steroids. TamoX capsules are twice the strength of normal dosed Tamoxifen which is usually 10mg which means you are getting twice the strength and twice the value with our capsules!

Clomiphene along with Tamoxifen is a mandatory part of any PCT. Tamoxifen should not be relied upon alone to recover the hypothalamic-pituitary-testicular axis (HPTA). HCG is most especially important to be included also, especially for individuals over the age of 30 where the HPTAxis, natural testosterone and sperm production is harder to recover than in your early twenties.

AeroX

AeroX by H2 LABS is an is an orally available suicidal aromatase inhibitor containing 20mgs of Exemestane. The active half-life of Exemestane is 27 hours.

We are very proud to announce the arrival of our new product AeroX. AeroX is a highly sought after compound used for estrogen control and also used to increase the availability of free testosterone. Aromasin also known as Exemestane is a third generation Aromatase Inhibitor (AI) just like Arimidex (Anastrozole) and Femera (Letrozole). At only 20-25mgs/day AeroX will raise your testosterone levels by about 60%, and also help out your free to bound testosterone ratio by lowering levels of Sex Hormone Binding Globulin (SHBG), by about 20%. SHBG is that nasty enzyme that binds to testosterone and renders it useless for building muscle. Type I inhibitors (like Aromasin) are actually steroidal compounds, while type II inhibitors (like Letro and A-dex) are non-steroidal drugs. Hence, androgenic side effects are very possible with Type-I AIs, and they should probably be avoided by women. Of course, there are some similarities between the two types of AIs…both type I & type II AIs mimic normal substrates (essentially androgens), allowing them to compete with the substrate for access to the binding site on the aromatase enzyme. After this binding, the next step is where things differ greatly for the two different types of AI’s. In the case of a type-I AI, the noncompetitive inhibitor will bind, and the enzyme initiates a sequence of hydroxylation; this hydroxylation produces an unbreakable covalent bond between the inhibitor and the enzyme protein. Now, enzyme activity is permanently blocked; even if all unattached inhibitor is removed. Aromatase enzyme activity can only be restored by new enzyme synthesis. Now, on the other hand, competitive inhibitors, called type II AI’s, reversibly bind to the active enzyme site, and one of two things can happen: 1.) either no enzyme activity is triggered or 2.) the enzyme is somehow triggered without effect. The type II inhibitor can now actually disassociate from the binding site, eventually allowing renewed competition between the inhibitor and the substrate for binding to the site. This means that the effectiveness of competitive aromatase inhibitors depends on the relative concentrations and affinities of both the inhibitor and the substrate, while this is not so for non competitive inhibitors. Aromasin is a type-I inhibitor, meaning that once it has done its job, and deactivated the aromatase enzyme, we don’t need it anymore. Letrozole and Arimidex actually need to remain present to continue their effects.

Aromasin is about 65% efficient at suppressing estrogen and there is also a decent amount of preclinical data suggesting that Aromasin has a beneficial effect on bone mineral metabolism that is not seen with non-steroidal agents, and it may also have beneficial effects on lipid metabolism that are not found in the non-steroidal Letro and A-dex. AeroX is the product we highly recommend using for on cycle estrogen protection in preference over TamoX.  Exemestane is an extremely expensive compound to acquire and is highly sought after which is why it's certainly not cheap but users will confirm that it's worth it's weight in gold.

 

Aromatase Inhibitor's (AI's)

Drugs from the aromatase-inhibiting family of medications work by blocking the creation of estrogen, in comparison to SERM'S which only block the circulating estrogen from receptors, and inturn makes AI's far superior. When taken in high dosages they can prevent up to 98% of the conversion of estradol from ever happening. For TRT purposes we highly recommend using either Liquid ArimiX or preferably Liquid LetroX to counteract the side effects should you ever experience side effects due to excessivly high dosage of testosterone.

Arimidex
Manufacturer: H2 LABS International
Active ingredient: Anastrozole
Product code: H2L 0574-037
Availability: In Stock
Pack: 20ml (5mg/ml)
Price: €55.00 EUR USD GBP

Box of 5: €220.00 EUR (€55 off) USD GBP

Dosage measured by:
1ml Insulin Syringe
5mg = 100IU
2.5mg = 50IU
1.25mg = 25IU
0.6mg = 12.5IU


Liquid ArimiX

Liquid ArimiX by H2 LABS is a non-steroidal anti-estrogen available in liquid form which contains 5mg of the substance Anastrozole per ml. The active half-life of Anastrozole is 46.8 hours.

It is only recommended that you remove your dosage with a 1ml insulin syringe to ensure accurate dosing.
Most commonly called Arimidex, this substance is a true aromatase inhibitor which works by blocking the aromatase enzyme in the body, thus limiting the amount of estrogen build-up that takes place. This compound has obvious benefits to bodybuilders who use aromatizing steroids such as testosterone. These individuals might face estrogen related side effects such as water bloat and "gyno", but by taking Liquid ArimiX while on cycle, the chance of any of these sides are greatly reduced.
In studies that have been done, Arimidex has been shown to reduce estrogen in the body by roughly 50%. This is a good balance for bodybuilders, because some estrogen is needed in order for the full anabolic benefits of the steroids being taken to be achieved. These results are typically the same with a dosage of .5 mg a day as they are with a dosage of 1 mg a day, meaning that in most cases, 12.5 IU per day will be sufficient for estrogen control throughout cycle and 1mg may be totally unnecessary.

Typically, bodybuilders using Liquid ArimiX will begin taking it the day they start their cycle, and will run it throughout the duration of steroid administration. It is also important to point out Liquid ArimiX’s ability to increase testosterone in the body. Some studies have shown that natural testosterone levels have increases as much as 60% after the use of this substance for 7 days. Because of this, bodybuilders find this drug extremely effective during PCT where as they are trying to elevate natural levels as much as possible in order to avoid a post cycle "crash".


 

Letrozole
Manufacturer: H2 LABS International
Active ingredient: Letrozole
Product code: H2L 0574-038
Availability: In Stock
Pack: 20ml (5mg/ml)
Price: €65.00 EUR USD GBP

Box of 5: €260.00 EUR (€65 off) USD GBP

Dosage measured by:
1ml Insulin Syringe
5mg = 100IU
2.5mg = 50IU
1.25mg = 25IU
0.6mg = 12.5IU


Liquid LetroX

Liquid LetroX by H2 LABS is an extremely potent non-steroidal anti-estrogen which contains 5mg of the substance Letrozole per ml. The active half-life of Letrozole is 2 days.

Firstly, as with Liquid ArimiX it is very important that you measure out your dosage in a 1ml insulin syringe by IU's in order to get the correct dosing, there is no room for error especially with LetroX as it is the most potent Aromatase Inhibitor (AI) of them all.

Letro, as it is most commonly called, was originally developed to help treat breast cancer in women. It can also have benefits to bodybuilders who are very sensitive to estrogen related side effects, or who are in heavy bulking cycles and taking large amounts of aromatizing hormones such as testosterone. This product is extremely potent at blocking estrogen in the body, and studies typically show that a relatively low dose of Letrozole can eliminate up to 98% of the estrogen in the body. Some subjects have even been shown to have no estrogen at all in their bodies after being administered Letrozole.
While too much estrogen can be harmful and bring about unwanted side effects, it's important that bodybuilders don't totally eliminate estrogen all together, for its presence is vital for optimum muscle growth and also for keeping a healthy sex drive.
H2 LABS LetroX is about 3 times stronger than Anastrozole, and would generally be used by those who have found that Anastrozole wasn't strong enough to keep estrogenic related side effects under control.

Another use for Letrozole might come to those who have already suffered from the estrogen related side effect, gyno. This is due to the fact that Letrozole has actually been shown to reverse the effects of this condition in some. There is no guarantee however, but if you have already begun seeing the symptoms of gyno, then it is probably worth giving Letrozole a shot and seeing if it can help.
This product could also be useful to those bodybuilders who are in contest prep and looking to be as dry as possible. Those using Letrozole will typically take around .5-1.0 mg per day or more commonly, every other day. Anything more than this will generally reduce estrogen too much in the body and hinder one’s sex drive.
