What’s RAD 140?
RAD 140, or testolone, is a non-steroidal SARM (selective androgen receptor modulator) that replicates the anabolic results of steroids by binding to the androgen receptor.
RAD 140 and different SARMs had been formulated to offer extra optimum remedy for sufferers affected by osteoporosis, cachexia, and anemia. Nonetheless, RAD 140 has not but been confirmed to be secure clinically.
Though anabolic steroids produce vital will increase in lean mass, in addition they induce unfavourable cardiovascular, hepatic, estrogenic, and androgenic unwanted effects. Thus, via the mechanism of tissue selectivity, RAD 140 was synthesized to duplicate the muscle-building and strength-enhancing attributes of steroids, however with restricted opposed results. Nonetheless, in observe, we observe RAD 140 replicating the toxicity of some anabolic steroids, comparable to Anavar or Primobolan.
RAD 140 surfaced in 2010 after being formulated by a US biotechnology firm, Radius Well being. There may be restricted scientific analysis concerning RAD 140’s results, notably on people over the long run.
RAD 140 is taken into account one of many stronger SARMs, possessing superior anabolic results to testosterone propionate in animal trials. In scientific settings, monkeys skilled a ten% enhance in lean physique mass over 28 days on RAD 140 [1].
Just like anabolic steroids, RAD 140 induces lipolysis and will increase muscular energy because of its excessive affinity when binding to androgen receptors.

Is RAD 140 Authorized?
Resulting from RAD 140’s latest creation, it has not been permitted for human use by the FDA. Thus, testolone is just authorized to purchase for investigational functions, particularly restricted to animal testing.
RAD 140 has additionally been banned by the World Anti-Doping Affiliation (WADA); due to this fact, skilled athletes are prohibited from utilizing it and different SARMs [2].
RAD 140 Earlier than and After Outcomes

- This Reddit person stacked RAD 140 with one other SARM, often called LGD-4033.
- He additionally administered MK-677, often called Ibutamoren.
MK-677 is also known as a SARM because of its related anabolic results. Nonetheless, it’s technically a development hormone secretagogue (GHS).
This person skilled vital muscle development, with some will increase in visceral fats, made seen by a notable enhance in abdomen hypertrophy.

Will increase in visceral fats could also be predominantly attributed to the inclusion of MK-677 on this stack, with HGH enhancers identified for rising insulin resistance and thus inducing visceral fats storage.
This person’s outcomes, when it comes to muscle hypertrophy, will be thought-about average—but lower than a typical first steroid cycle.
As a visible estimate, this person seems to have gained 10 kilos (4.5 kg) of lean mass.
In animal trials, RAD 140 has produced vital will increase in muscle hypertrophy; nevertheless, in people, we see a milder impact.
Human trials have in contrast the anabolic results of testosterone enanthate versus SARMs. Researchers discovered that SARMs added 1-1.5 kg of lean mass to individuals over 4-6 weeks, whereas testosterone enanthate added 5-7 kg of lean mass [3].
RAD 140-Solely Cycle: Earlier than and After
This Reddit person’s cycle:
| Week | RAD 140 dosage |
|---|---|
| Week 1-12 | 17 mg/day |
- He skilled modest enhancements in muscularity, albeit with a rise in subcutaneous physique fats.
- He gained 5 lb (2.3 kg) in weight, with a few of this being within the type of adipose tissue, because of 12 weeks of consuming in a modest calorie surplus.
Compared to the primary RAD 140 earlier than and after transformation, this person has not gained a notable quantity of visceral fats, indicating that the opposite person’s enhance in intestine dimension was MK-677-related.
Some may hypothesize that this person’s RAD 140 (Testolone) is probably not reliable or diluted because of an absence of outcomes. Nonetheless, this person’s supply was verified to be a trusted producer.
RAD 140 Earlier than and After: 8-Week Cycle
- The above Reddit person administered lower than 10 mg/day of RAD 140 for almost all of his 8-week cycle, demonstrating that optimum outcomes can nonetheless be skilled at a low dosage.
- This person skilled vital fats loss regardless of claiming to eat in a calorie surplus. He’s displaying enhanced muscle hardness, definition, and thickness.
Regardless of gaining 10 kilos on the scales, he personally acknowledged that RAD 140 was not value it for him. This was as a result of his outcomes had been “unsubstantial,” and he skilled some hair loss.
This person’s expertise signifies that low dosages of RAD 140 could enhance the reward-to-risk ratio, with him gaining 10 kilos and dropping a noticeable quantity of subcutaneous fats concurrently. Nonetheless, people prone to male sample baldness could expertise some shedding on RAD 140.
RAD 140 Dosage
RAD 140 shouldn’t be a pharmaceutically produced compound because of an absence of FDA approval. Thus, there aren’t any dosage tips.
Nonetheless, we see males generally take 10-20 mg/day for 6-12 weeks to reinforce physique composition.
What’s a Commonplace RAD 140 Cycle for Males?
| Week | RAD 140 Dosage |
|---|---|
| Week 1-8 | 10 mg/day |
Ladies generally take 5-10 mg/day for the same length, enabling them to expertise the advantages of RAD 140 however with none virilizing results.
What’s a Commonplace Feminine RAD 140 Cycle for Females?
| Week | RAD 140 dosage |
|---|---|
| Week 1-8 | 7.5 mg/day |
RAD 140 usually is available in 10 mg capsules or a ten mg/mL liquid resolution.
What Are the Facet Results of RAD 140?
In animal research, RAD 140 has been proven to be much less poisonous than testosterone substitute remedy when administered to rats [4].
Nonetheless, in people, there seems to be a special development, with RAD 140 demonstrating harsher unwanted effects in some customers. Dr. Nicholas Downey says that present analysis signifies that RAD 140 causes “liver points” at 50 mg/day. He additionally notes that RAD 140 is “fairly suppressive,” however the extent of this impact is unknown because of an absence of human research.
Liver Toxicity
There may be present analysis indicating RAD 140’s capacity to trigger hepatocellular-cholestatic liver harm.
A 49-year-old man had taken RAD 140 constantly for 4 weeks [5], with intermittent use afterward. He administered RAD 140 together with an antidepressant (venlafaxine) that he had beforehand been taking for 11 months.
The person’s alcohol consumption was insignificant. Due to this fact, the mix of hepatotoxic antidepressants and SARMs could also be a deleterious mixture.
The person within the second RAD 140 before-and-after image additionally reported excessively raised alanine transaminase (ALT) and aspartate aminotransferase (AST) enzymes, demonstrating liver stress.
Dr. Thomas O’Connor, in his expertise of analyzing over 2,000 sufferers on SARMs over a decade, has likened SARMs to taking 50 mg/day of Anavar.
Dr. Ankit Batra additionally affirms that in scientific research, the hepatic problems of RAD 140 “will be much like anabolic steroids,” regardless of ALT and AST enzymes generally normalizing post-cycle.
RAD 140’s route of entry, being an oral product, is the primary explanation for hepatic stress.
This is because of it having to bypass the liver upon coming into the bloodstream, much like C-17 alpha-alkylated steroids, inflicting hepatotoxicity.
Blood Strain
Now we have discovered that RAD 140, in addition to different SARMs, has a dose-dependent impact on ldl cholesterol [6], rising the chance of:
- Atherosclerosis
- Myocardial infarction
The second person who revealed his before-and-after transformation reported a big rise in blood strain.
That is doubtless because of SARMs passing via the liver, which stimulates the hepatic lipase enzyme, inflicting HDL levels of cholesterol to lower. HDL ldl cholesterol is useful to coronary heart well being, with excessive ranges decreasing arterial plaque [7].
One other doable contributing issue to undesirable blood lipids could also be RAD 140’s lack of aromatization. In distinction, a number of anabolic steroids convert to estrogen, inflicting much less vital shifts in levels of cholesterol. It is because estrogen has a optimistic impact on HDL ranges, so inhibiting this conversion shouldn’t be optimum for cardiovascular well being.
Testosterone Suppression
RAD 140’s aggressive binding impact with the androgen receptor can suppress testosterone ranges, much like anabolic steroids.
The extent of such suppression on SARMs has not but been established. Nonetheless, our anecdotal information suggests it’s vital. The second person within the before-and-after transformation administered 17 mg/day of RAD 140 for 12 weeks and skilled a notable decline in testosterone ranges, dropping from 750 to 193 ng/dL.
Thus, we now have discovered that scientific hypogonadism is feasible with RAD 140 through harm to the hypothalamic-pituitary-testicular axis (HPTA), probably impacting customers’ long-term fertility.
All SARMs seem to have a suppressive impact on endogenous testosterone. Nonetheless, RAD 140’s influence appears to be extra pronounced than different SARMs because of it being a stronger compound.
Gynecomastia and Water Retention
Though RAD 140 doesn’t aromatize, it could possibly nonetheless elevate estrogen ranges through a special pathway. When SARMs are administered, they start to compete with a person’s pure testosterone for binding to the androgen receptor. SARMs win this battle because of their superior binding affinity, leaving extra free testosterone to transform to estrogen or dihydrotestosterone (DHT), consequently elevating each of those hormones.
Elevated ranges of estrogen could cause:
- Water retention
- Bloating
- Gynecomastia
Dr. Michael Moeller states that he has overseen male sufferers lactating from SARM use, together with RAD 140. Thus, possessing a gentle aromatase inhibitor (AI) when commencing a RAD 140 cycle will be advantageous.
Androsta-3,5-diene-7,17-dione, in any other case known as arimistane, is a gentle AI that may be utilized to inhibit estrogenic unwanted effects.
In our expertise, stronger AIs are more likely to be excessively harsh for a SARM cycle, comparable to:
- Letrozole
- Aromasin
- Anastrozole
The above AIs could trigger a hormonal imbalance, inflicting an estrogen deficiency. Potent AIs are extra appropriate for anabolic steroid cycles, the place estrogen ranges rise significantly.
Hair Loss and Prostate Enlargement
It was thought that RAD 140 could also be useful for benign prostatic hyperplasia because of its profitable tissue selectivity, inflicting prostate shrinkage in animal analysis. In rats, RAD 140 demonstrated low ranges of androgenicity. The rats required a 60-times increased dosage to duplicate the prostatic hypertrophy of testosterone [8].
Nonetheless, we now have had RAD 140 customers nonetheless expertise bouts of hair loss. This can be attributed to pure testosterone changing to DHT, with the previous not binding to androgen receptors.
Larger DHT ranges will trigger elevated irritation and hair miniaturization on the scalp.
If customers make the most of RAD 140 for short-term use, such hair loss could reverse when hormones regulate again to regular post-cycle. Nonetheless, long-term use and sustained excessive ranges of DHT enhance the chance of androgenetic alopecia.
Elevated sebum manufacturing can also be doable, inflicting delicate customers to probably expertise pimples vulgaris.
In idea, RAD 140’s tissue selectivity ought to forestall any androgenic unwanted effects, that are portrayed in animal analysis. Nonetheless, its oblique influence on pure testosterone changing to DHT could also be problematic for human customers.
RAD 140 PCT
RAD 140 suppresses testosterone through the reducing of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), a consequence of its binding affinity to androgen receptors.
Some RAD 140 customers test their testosterone ranges post-cycle, with the information signifying notable suppression, inflicting them to bear post-cycle remedy (PCT).
Customers can start PCT 12 days after ending a RAD 140 cycle, based mostly on its half-life of 60 hours. The elimination time is the half-life multiplied by 5.5.
Usually, we’d prescribe Clomid or Nolvadex for PCT, with the latter being the stronger treatment for restoring endogenous testosterone.
Clomid could also be enough for post-cycle remedy if conducting a RAD 140-only cycle. Nonetheless, Nolvadex is more likely to be extra optimum if stacking RAD 140 with different SARMs.
By way of the dosage and length of a RAD 140 PCT protocol, under are a few pattern cycles.
| Length | Nolvadex dosage |
|---|---|
| Day 1-30 | 20 mg/day |
| Length | Clomid dosage |
|---|---|
| Day 1-30 | 25 mg/day |
Authorized RAD 140 Various
TESTOL 140 is our beneficial RAD 140 various, mimicking the anabolic results of RAD 140 however with none testosterone suppression or liver toxicity.
It’s FDA-approved and thus authorized to buy for human consumption.
TESTOL 140 is finest utilized when bulking for max hypertrophy and energy. It can additionally inhibit fats acquire when consuming in a calorie surplus.
What’s the Half-Lifetime of RAD 140?
Based mostly on pharmacokinetic samples, RAD 140’s half-life is 60 hours [9]. Nonetheless, every day dosing stays a typical protocol amongst customers, who initially estimated its half-life to be roughly 20 hours.
RAD 140 vs. LGD-4033: How Do They Examine?
LGD-4033, or Ligandrol, is the stronger SARM per milligram. Now we have discovered that dosages of solely 2-10 mg are essential to see notable outcomes from LGD-4033. RAD 140’s dosage is usually 10-20 mg.
RAD 140 appears to be a superior SARM in regard to elevated pumps and subcutaneous fats loss.
Thus, when it comes to aesthetics, RAD 140 could also be thought-about extra optimum. LGD-4033 causes extra water retention; due to this fact, it is probably not advantageous for customers searching for a lean physique and most muscle definition.
A portion of the fats loss related to RAD 140 could also be oblique, because of its urge for food suppressant results, that are superior to LGD-4033’s [10].
By way of muscle hypertrophy and energy, LGD-4033 and RAD 140 are related in efficiency.
We discovered that RAD 140 has a stronger muscle-hardening impact, probably because of estrogen ranges rising much less [11] and thus reducing water retention.
RAD 140 is more likely to produce extra distinguished outcomes when it comes to muscular endurance, benefiting those that carry out excessive numbers of repetitions or have a coaching schedule that includes common cardiovascular coaching.
In our expertise, customers report increased power ranges on RAD 140 than LGD-4033.
LGD-4033, nevertheless, is thought to extend libido greater than RAD 140 on-cycle.
| RAD 140 value | LGD-4033 value |
|---|---|
| $64.99 | $59.99 |

What Can RAD 140 Be Stacked With?

RAD 140 can theoretically be cycled with any SARM. Such stacking enhances muscular energy, hypertrophy, and fats loss. Nonetheless, using a number of SARMs concurrently also can exacerbate unwanted effects.
Novices usually full a RAD 140-only cycle initially to turn out to be accustomed to the drug. As a person beneficial properties expertise, a stronger stack is often utilized, comparable to RAD 140 and LGD-4033, for added mass and energy outcomes when bulking.
By way of dosages, a RAD 140 and LGD-4033 stack can look as follows:
| Week | RAD 140 dosage | LGD-4033 dosage |
|---|---|---|
| Week 1-8 | 10 mg/day | 6 mg/day |
Nonetheless, given the early indications of RAD 140’s hepatotoxic results on people [12] and its unfavourable results on blood lipids, it is probably not clever to stack it with additional non-steroidal SARMs till it’s higher understood.
