Spoiler: The benefits of using Tamoxifen

Tamoxifen offers two main benefits for teenagers, particularly adolescent boys, when used off-label.

1. Height potential

E2 drives epiphyseal (growth plate) closure in both sexes during late puberty. Read my last thread about e2 HERE
THIS IS WELL DOCUMENTED for all of you retards disagreeing Google is free
I really recommend you read my last thread. This will make what im about to explain a lot easier.

Tamoxifen works in bone maturation by modulating estrogen receptor alpha (ERα) activity in growth plate chondrocytes.

During late puberty, e2 produced locally via aromatase from androgens or systemically binds to ERα in the epiphyseal growth plates. This activates ERα, which translocates to the nucleus and promotes gene expression that accelerates chondrocyte senescene, reduces proliferation in the proliferative zone, and stimulates hypertrophic differentiation and ossification. The net result is progressive advancement of bone age and eventual epiphyseal fusion, which halts linear growth.

Tamoxifen, as a SERM, binds competitively to ERα in bone tissue. It induces a receptor conformation that favors recruitment of co-repressors over co-activators in this context, thereby antagonizing estrogen’s maturational effects. This slows the rate of skeletal maturation without fully eliminating estrogen signaling. The result is a prolonged period of chondrocyte activity and delayed growth plate closure, extending the growth window.

Tamoxifen is only a partial antagonist in bone. Its SERM nature means it can exhibit some residual agonist-like effects or incomplete blockade depending on cellular context and co-regulator availability. It does not degrade the receptor. While it may not have the same effect as a full on SERD like Fulvestrant which binds ERα with high affinity, induces a different conformational change that leads to ubiquitination and proteasomal degradation of the receptor itself. Altough SERDs would theoretically offer far greater and more potent e2 suppression and more height gains they are typically not used due to them usually being injectable and having a far greater side effect profile. This is not what the thread is about tho.

To back these claims up I have some studies im gonna link.

The Primary Tamoxifen study for increasing FAH (Final adult height) is Kreher NC, Eugster EA, Shankar RR. The Use of Tamoxifen to Improve Height Potential in Short Pubertal Boys. Pediatrics. 2005.

Retrospective chart review of 7 short pubertal boys treated with tamoxifen. It showed significantly slowed skeletal maturation and increased predicted adult height (nearly 4 inches or 10 cms on average) without apparent negative effects on sexual maturation.

Keep in mind this is only on the e2 axis. A lot more can be done when this is paired with different biological pathways like the IGF-1/PTHrP/IHH or any other pathway for that matter.

If you want to ead a couple more very high IQ articles il link them here:

• Review on delaying growth plate closure (2024): Discusses tamoxifen/SERMs as off-label options alongside more commonly studied aromatase inhibitors.ISPAE Journal
• Broader review on manipulating skeletal maturation (2021): Covers estrogen modulation (including SERMs and aromatase inhibitors) for height in various growth disorders.Frontiers in Endocrinology

While this thread is focused only on SERMs go ahead and checkout some other Threads on much more studied Aromatase Inhibitors. I recommend you stack SERMs + AIs for maximal Growth.

2. Gynecomastia (enlarged breast tissue)

Pubertal gynecomastia is common due to temporary estrogen-androgen imbalance. Tamoxifen, as a SERM, blocks estrogen action specifically in breast tissue
I will not be going into depth on this topic as I am pretty sure there are some decent threads on Tamoxifen in the context of Gyno already.

Why People believe Tamoxifen does induce apoptosis and permanent Growth retardation
+ Why this is not True and retarded

​

Spoiler: Why Tamoxifen does not induce apoptosis

When People say Tamoxifen causes permanent Growth Retardation they usually refer to this study here and this one

Which is generally retarded and JFL

Here is a quick Summary:
In an ex vivo organ culture of fetal rat metatarsal bones, tamoxifen caused dose-dependent shortening with increased chondrocyte apoptosis (via caspases and FasL/Fas). No recovery occurred after removal, indicating permanent arrest. A related in vivo follow-up (Karimian et al., 2008) in young male rats showed persistent shorter tibia and reduced cortical bone even after recovery, with elevated apoptosis and proliferation imbalance plus lower IGF-1.

The Reasearchers behind this paper identified a novel mechanism where tamoxifen activates the Fas ligand (FasL)/Fas death receptor pathway in chondrocytes. This leads to sequential caspase activation (caspase-8 first, then -9 and -3), executing apoptosis. This pathway is triggered independently of (or differently from) typical estrogen blockade, possibly due to tamoxifen’s unique receptor conformation in chondrocytes or non-genomic effects.

Basically Tamoxifen in a dose-dependent context activates a death recptor pathway leading to chondrocytes dying instead of multiplying (proliferation).

It's important that you notice the word dose-dependant. The Young (4-week-old) male Sprague-Dawley rats received 40 mg/kg/day tamoxifen (JFL) by oral gavage (peanut oil vehicle) for 1 or 4 weeks. Researchers described this as a clinically relevant dose based on comparisons to human therapeutic use at the time.

The important part is to now translate this into human dose which is usually done by using allometric scaling uses body surface area (BSA) via Km factors (FDA/EMA guideline approach):

Standard allometric scaling uses body surface area (BSA) via Km factors (FDA/EMA guideline approach):

1. Identify animal dose: 40 mg/kg/day (rat).
2. Rat Km factor (for ~150–250 g rat): 6.
3. Human Km factor (adult 60–70 kg): 37.
4. Conversion factor = Human Km / Rat Km = 37 / 6 ≈ 6.2.
5. HED (mg/kg) = Rat dose (mg/kg) ÷ 6.2.

Calculation: 40 mg/kg ÷ 6.2 ≈ 6.45 mg/kg/day in humans.

Now translating this type of dose into a revelant daily human dose for a normal 60 kgs teen it would be ~387 mg/day (JFL)

If we comapre this to the study where Tamoxifen significantly increased FAH the average dose was 20mg ed in spit dosage format (10mg morning 10mg evening)

This is a absurdly high dose considering 20 mgs a day is enough to give you amazing results. No non-tarded nigger is EVER i repeat EVER on such a high dose of Nolvadex. The rat-derived HED is roughly 15–40 times higher than common clinical doses used in adolescents.

I will now explain to "zhe Iqlets" why High rat doses trigger FasL and low human doses do NOT. (In before muh FasL will always be active muh)

The FasL/Fas pathway activation by tamoxifen is dose and concentration dependent because it likely involves non-genomic, off-target effects that only become prominent when intracellular tamoxifen (or it metabolites) reaches sufficiently high levels. At lower concentrations, the dominant action is SERM-mediated ERα antagonism, which modulates gene expression without strongly engaging pro-apoptotic death receptor signaling.

At low nanomolar to low micromolar levels (typical of 20 mg human dosing), tamoxifen and its active metabolites primarily bind ERα with high affinity. This induces a specific receptor conformation that recruits co-repressors in certain tissues, blocking estrogen-driven transcription without broadly disrupting cell survival pathways. The FasL promoter or related signaling remains minimally affected or not at all.

In the micromolar range (as used in Chagin et al. ex vivo cultures), tamoxifen accumulates in cells and interacts with additional targets beyond ER: Tamoxifen can alter membrane fluidity, inhibit protein kinase C (PKC), or affect calcium signaling and oxidative stress pathways. These changes can indirectly promote transcription or secretion of FasL (via stress-activated kinases like JNK or other transcription factors). Secreted FasL then binds Fas (CD95) on the same or adjacent chondrocytes, forming the Death-Inducing Signaling Complex (DISC) with FADD, activating caspase-8 (initiator), which cascades to caspase-9 and -3. This extrinsic apoptosis pathway is efficiently engaged only above a concentration threshold where these secondary effects dominate.

Pour moi DNR Niggers: The scary permanent damage happened at absurdly high experimental doses no one uses. Standard 20 mg stays in the safe SERM zone.

We can also look at real-world data and documented evidence in pubertal boys with Gynecomastia:

Akgül S, et al. (2016). "The effect of tamoxifen on pubertal bone development in adolescents with pubertal gynecomastia." - link

Studied 20 boys treated with tamoxifen (at least 4 months). Assessed BMD, bone age, and height before and 1 year later. They found no significant effect on skeletal maturation (p=1.112). Bone mineralization increased as expected during puberty (Z-scores stable) and concluded Tamoxifen is safe for pubertal bone development and neither growth potential nor BMD was negatively affected. No signs of apoptosis-related damage or reduced height potential.

There are tons of other studies that your little lazy ahh can serach up and read yourself.

My personal advice is if you want to get meaningful height gains from Tamo you should not have any Gyno as the paper above showed no *significant* height gains. Fix your gyno first.

Keep in mind this is only on the e2 axis. A lot more can be done when this is paired with different biological pathways like the IGF-1/PTHrP/IHH or any other pathway for that matter.

If you want to ead a couple more very high IQ articles il link them here:

• Review on delaying growth plate closure (2024): Discusses tamoxifen/SERMs as off-label options alongside more commonly studied aromatase inhibitors.ISPAE Journal
• Broader review on manipulating skeletal maturation (2021): Covers estrogen modulation (including SERMs and aromatase inhibitors) for height in various growth disorders.Frontiers in Endocrinology

While this thread is focused only on SERMs go ahead and checkout some other Threads on much more studied Aromatase Inhibitors. I recommend you stack SERMs + AIs for maximal Growth.

2. Gynecomastia (enlarged breast tissue)

Pubertal gynecomastia is common due to temporary estrogen-androgen imbalance. Tamoxifen, as a SERM, blocks estrogen action specifically in breast tissue
I will not be going into depth on this topic as I am pretty sure there are some decent threads on Tamoxifen in the context of Gyno already.

Why People believe Tamoxifen does induce apoptosis and permanent Growth retardation
+ Why this is not True and retarded

​

Spoiler: Why Tamoxifen does not induce apoptosis

When People say Tamoxifen causes permanent Growth Retardation they usually refer to this study here and this one

Which is generally retarded and JFL

Here is a quick Summary:
In an ex vivo organ culture of fetal rat metatarsal bones, tamoxifen caused dose-dependent shortening with increased chondrocyte apoptosis (via caspases and FasL/Fas). No recovery occurred after removal, indicating permanent arrest. A related in vivo follow-up (Karimian et al., 2008) in young male rats showed persistent shorter tibia and reduced cortical bone even after recovery, with elevated apoptosis and proliferation imbalance plus lower IGF-1.

The Reasearchers behind this paper identified a novel mechanism where tamoxifen activates the Fas ligand (FasL)/Fas death receptor pathway in chondrocytes. This leads to sequential caspase activation (caspase-8 first, then -9 and -3), executing apoptosis. This pathway is triggered independently of (or differently from) typical estrogen blockade, possibly due to tamoxifen’s unique receptor conformation in chondrocytes or non-genomic effects.

Basically Tamoxifen in a dose-dependent context activates a death recptor pathway leading to chondrocytes dying instead of multiplying (proliferation).

It's important that you notice the word dose-dependant. The Young (4-week-old) male Sprague-Dawley rats received 40 mg/kg/day tamoxifen (JFL) by oral gavage (peanut oil vehicle) for 1 or 4 weeks. Researchers described this as a clinically relevant dose based on comparisons to human therapeutic use at the time.

The important part is to now translate this into human dose which is usually done by using allometric scaling uses body surface area (BSA) via Km factors (FDA/EMA guideline approach):

Standard allometric scaling uses body surface area (BSA) via Km factors (FDA/EMA guideline approach):

1. Identify animal dose: 40 mg/kg/day (rat).
2. Rat Km factor (for ~150–250 g rat): 6.
3. Human Km factor (adult 60–70 kg): 37.
4. Conversion factor = Human Km / Rat Km = 37 / 6 ≈ 6.2.
5. HED (mg/kg) = Rat dose (mg/kg) ÷ 6.2.

Calculation: 40 mg/kg ÷ 6.2 ≈ 6.45 mg/kg/day in humans.

Now translating this type of dose into a revelant daily human dose for a normal 60 kgs teen it would be ~387 mg/day (JFL)

If we comapre this to the study where Tamoxifen significantly increased FAH the average dose was 20mg ed in spit dosage format (10mg morning 10mg evening)

This is a absurdly high dose considering 20 mgs a day is enough to give you amazing results. No non-tarded nigger is EVER i repeat EVER on such a high dose of Nolvadex. The rat-derived HED is roughly 15–40 times higher than common clinical doses used in adolescents.

I will now explain to "zhe Iqlets" why High rat doses trigger FasL and low human doses do NOT. (In before muh FasL will always be active muh)

The FasL/Fas pathway activation by tamoxifen is dose and concentration dependent because it likely involves non-genomic, off-target effects that only become prominent when intracellular tamoxifen (or it metabolites) reaches sufficiently high levels. At lower concentrations, the dominant action is SERM-mediated ERα antagonism, which modulates gene expression without strongly engaging pro-apoptotic death receptor signaling.

At low nanomolar to low micromolar levels (typical of 20 mg human dosing), tamoxifen and its active metabolites primarily bind ERα with high affinity. This induces a specific receptor conformation that recruits co-repressors in certain tissues, blocking estrogen-driven transcription without broadly disrupting cell survival pathways. The FasL promoter or related signaling remains minimally affected or not at all.

In the micromolar range (as used in Chagin et al. ex vivo cultures), tamoxifen accumulates in cells and interacts with additional targets beyond ER: Tamoxifen can alter membrane fluidity, inhibit protein kinase C (PKC), or affect calcium signaling and oxidative stress pathways. These changes can indirectly promote transcription or secretion of FasL (via stress-activated kinases like JNK or other transcription factors). Secreted FasL then binds Fas (CD95) on the same or adjacent chondrocytes, forming the Death-Inducing Signaling Complex (DISC) with FADD, activating caspase-8 (initiator), which cascades to caspase-9 and -3. This extrinsic apoptosis pathway is efficiently engaged only above a concentration threshold where these secondary effects dominate.

Pour moi DNR Niggers: The scary permanent damage happened at absurdly high experimental doses no one uses. Standard 20 mg stays in the safe SERM zone.

We can also look at real-world data and documented evidence in pubertal boys with Gynecomastia:

Akgül S, et al. (2016). "The effect of tamoxifen on pubertal bone development in adolescents with pubertal gynecomastia." - link

Studied 20 boys treated with tamoxifen (at least 4 months). Assessed BMD, bone age, and height before and 1 year later. They found no significant effect on skeletal maturation (p=1.112). Bone mineralization increased as expected during puberty (Z-scores stable) and concluded Tamoxifen is safe for pubertal bone development and neither growth potential nor BMD was negatively affected. No signs of apoptosis-related damage or reduced height potential.

There are tons of other studies that your little lazy ahh can serach up and read yourself.

My personal advice is if you want to get meaningful height gains from Tamo you should not have any Gyno as the paper above showed no *significant* height gains. Fix your gyno first.

Pair them. Its the best of both worlds

 

[Paul.jnxy]

For full estrogen modulation do you fuck with 0.5 letro 12.5 aromasin and 20 tamox

Thats already better. Im on that currently and planning on upping the dose

 

[Paul.jnxy]

And on the infig aspect isn’t it that it shows less eye issues and there’s no way to fight those eye issues

Yes there is. Im sorry boyo you should not be on any type of inhibitory yet if you don't know that inhbiton of FGFR1/2 cause retinal fluid build up. You can fight this with asthaxanthin + zeaxanthin + lutein and cycling on and off for 1 or 2 weeks

 

[lilcrodyshe]

Yes. A combo imo is best. Im currently on 12.5 mg aromasin (eod) + 0.625 letro (eod) and 10 mg Tamoxifen ed without being on any androgens. I will be upping them more when I hop on androgens and if I tolerate them will double all the doses.

I’m running almost the exact same combo, ever since I started my libido has tanked. Have you noticed the same?

 

[Paul.jnxy]

Yes. Quite significantly. I used to jack off ed and now its like once a week. Dw it should come back once you are on androgens tho.

 

[lilcrodyshe]

What androgens are you gonna add in? I’ve heard mixed things on aas effects on fah

 

[Paul.jnxy]

Im not sure yet. For sure a test base tho at like 10 mg low dose anavar 10 mg ed. A DHT Deriv (probs mast or primo instead of stanalone) and perhaps some proviron for SHBG binding but not much point in it tho. If I get a lot of money id probably get a PTHrP aswell and a FGFR3 inhib. Im not 100% sure yet tho. Where do you source your stuff?

I’m not running any androgens, my hgh is pharma grade because I got it perscribed by an endo. And the ai’s I got because my mom used her medical license to pick them up from cvs.That’s about all I’m running. As for an fgfr3 inhibitor I’ve found a few tele accounts and other research chem sites that supposedly sell them but I have not ordered yet.

Long story man, but all I really had to do was convince my mom because she works in the medical field. After I convinced her she was able to pull some strings with the endo to get her to prescribe me hgh.

I was running 14 ius for like a year and i recently dropped to 9 ius

 

[treyu12464]

I use micro dose letro+non aromatixable androgens (tren and halo) why combine all 3?

do you use test too? or without

 

[Paul.jnxy]

do you use test too? or without

without atm

 

[curryascension]

Skimmed seems correct
I use a low dose on cycle to prevent gyno

how tall ru and what was ur predicted height and base height before hopping on and do you take anything else

 

[tommyhilinger]

Tamox lowers igf1 buddy pretty counter intuitive dont you think
