Hair loss and hair thinning are pretty common amongst men, I’m sure we’ve all seen the “2 out of 3 men” advertisements…

While something like Finasteride is an effective treatment, it does have a pretty big side effect. Not great having a full head of thick hair but the old chap downstairs ain’t working.

Peptides for Hair Growth provide an interesting solution, as these compounds could end up promoting hair growth without causing too many adverse effects.

Peptides have very few sides in general, and they certainly have more benefits than just hair growth. Let’s have a look at the best ones and where you can find them.

Key Takeaways

  • The best Peptides for hair growth are RU58841 and Copper Peptides.
  • Certain Peptides could help by improving blood circulation, like BPC 157.
  • These Peptides have very few side effects.
  • The best way to get these is through a legitimate HRT Clinic.

BPC 157 (Hair Regrowth)Stimulates angiogenesisMay help regrow hair follicles, aids in healingAvailable onlineLimited scientific evidence
GHK-Cu (Copper Peptide)Blocks DHT, stimulates blood flowPromotes hair growth, skin health, and healingAvailable onlinePossible allergic reactions
HGH (Human Growth Hormone)Increases IGF-1 levelsImproves hair health, overall well-beingPrescription neededVariable effectiveness, costly

Looking at the best Peptides for hair growth, you can take various approaches seeing as hair regrowth can happen for a host of reasons.

Increased IGF-1 [1], lowering DHT [2], and even increasing the amount of blood flow could help [3].

Looking at all the data, there are actually a few different Peptides to not only improve the hair growth cycle but also ensure that there is decreased hair loss.

Because these compounds are very different from one another, it is impossible to say one is better than the other.

Taking that into consideration, here are the best ones you can get your hands on:

Best DHT Blocker

#1 RU58841

Created by French company Roussel Uclaf, this Peptide has been known to stop DHT, or Dihydrotestosterone, from binding to the hair follicles. DHT is known as the main cause of hair loss.

This is somewhat similar to how Finasteride works, as blocking DHT from binding to the AR, or Androgen Receptor could minimize Androgenetic alopecia. The benefit of RU58841 over Finasteride is that it will not cause Erectile problems.

For this Peptide to work, you would need to apply it daily and consistently, as the shedding phase can begin at any moment if DHT becomes too active. It is applied topically. It is commonly used with Minoxidil as the latter will cause hair growth, and the former will stop hair loss.

#2 Glutathione

Glutathione is an interesting Peptide seeing as its primary goal doesn’t have anything to do with hair. Glutathione is known as the most abundant antioxidant in the human body and is critical to human health.

There are some studies linking oxidative stress to hair loss, and other worrying factors like cardiovascular disease [4]. We also know that as we age, we see a massive reduction in Glutathione levels, which can lead to free radical damage, skin damage, and even an inability to fight inflammation.

Long-term Glutathione deficiency has been linked to poor hair density, and thus, supplementing with Glutathione will not only help with pattern hair loss but every other part of the human body as well.

  • Beneficial for every cell in the body
  • Not as effective as other Peptides on this list
BPC 157 Summary


BPC-157, or pentadecapeptide, is categorized as a body protection compound. It is composed of 15 amino acids in a very particular sequence that doesnโ€™t exist naturally.

It is artificially synthesized in laboratories using the partial sequence of the body-protecting compounds isolated from gastric juices. Hence, it is one of the derivatives of the peptide found in human gastric juices.

The therapeutic effects of BPC-157 are exerted through multiple courses of action. One of the most common ways that BPC-157 acts as a therapeutic agent is by carrying out angiogenesis, which is the formation of new blood vessels.ย 

It does this by activating a protein called the โ€œvascular endothelial growth factorโ€ which initiates the formation of new blood vessels. This ensues in the organization of a healthy vascular network which gives BPC-157 its key regenerative and healing properties.

Another mechanism of action of BPC-157 is blocking the inhibitory growth factor called 4-hydroxynonenal, which is a negative modulator of growth. This allows theย peptide to carry out effective healingย of wounds, especially surrounding tendons.

#4 GHK-Cu

Human copper-binding peptide GHK-Cu (glycyl-l-histidyl-l-lysine) is a common Peptide when looking at hair growth treatments. Copper Peptides in general are well-received in the medical world.

GHK-Cu and other Copper Peptides could battle hair loss and stimulate hair growth by stopping the production of DHT, and can also help the body stimulate blood flow by creating new blood vessels.

GHK-Cu is a specific Copper Peptide that has been linked to new hair growth, improving skin health, protecting skin cells from UV radiation, reducing inflammation and free radical damage, and enlarging hair follicle size [5].

#5 HGH – Human Growth Hormone

HGH or Human Growth Hormone is the hormone produced by the pituitary gland in all humans. In adolescents, HGH is important for growth and the development of the human body.

As we age, we see a reduction in natural HGH levels, which can be treated by an HRT Clinic. Once administered, HGH will cause an increase in IGF-1, or Insulin-like Growth Factor 1. IGF-1 will affect follicular proliferation and the hair development cycle, and various studies are showing it is somewhat effective [1].

While more studies are needed, and most of the current studies show that HGH is more effective in females than males, it is still pretty good. The reason is the mountain of other benefits it has such as healing properties, healthier skin, and even fat loss as well.

  • Improved Hair Health
  • Improved overall health as well as increased fat loss
  • More effective in females than males
  • Not as effective as previously thought
  • More effective in those suffering from a GH deficiency
  • Very expensive

What are Peptides?

Peptides can be defined as chains of Amino Acids that are bound with Peptide bonds – hence the name.

Depending on the sequence and the length of the Amino Acid chain, you can expect different physiological results when administered to the human body.

Amino Acids are the building blocks of Protein, however, in Peptide form they can do way more than just build muscle

The most common of these is Human Growth Hormone which is naturally produced by the body but can be administered exogenously.

Figure 1: Angiogenesis is one of the ways Peptides can increase blood flow, thereby possibly increasing hair growth

Scientists have noticed that certain Peptides have anti-inflammatory properties, and can even decrease hair loss.

It is important to remember that Peptides all differ from one another, and their mechanisms of action are very different as well.

How Do Hair Growth Peptides Work?

If you want to purchase the best peptides for hair growth, you need to know how they work.

Hair growth peptides are a diverse group of compounds designed to stimulate hair regrowth and combat hair loss, each working through specific mechanisms. 

The effectiveness of these peptides can vary, but their overall goal is to promote healthier hair growth

Two common ways in which hair growth peptides work include increasing blood flow and blocking dihydrotestosterone (DHT).

Certain peptides, like copper peptides, work by promoting better blood circulation to the scalp. 

Improved blood flow provides essential nutrients and oxygen to hair follicles, encouraging their activity and promoting the growth of thicker, healthier hair. 

By enhancing blood flow, these peptides create a more favorable environment for hair growth, particularly in cases where hair loss is related to poor circulation.

DHT, a hormone derived from testosterone, plays a significant role in androgenetic alopecia (male and female pattern baldness). 

Some hair growth peptides target DHT by inhibiting its production or binding to the androgen receptors in hair follicles. 

By reducing DHT levels or its harmful effects on the follicles, these peptides help prevent hair loss and encourage regrowth.

Different peptides may work through varying combinations of these mechanisms. 

The choice of peptide and its effectiveness depend on the specific type of hair loss and its underlying causes.

Understanding the root cause of hair loss is essential to selecting the right peptide treatment. 

Hair growth peptides are often incorporated into topical formulations, making them convenient for regular application to the scalp. 

While some people may experience positive results, it’s essential to consult with a healthcare professional before using any peptide-based hair growth product to ensure it’s safe and suitable for your specific condition.

Where to get the Best Peptides for Hair Growth

One of the easiest ways to combat hair loss is to find out why it’s happening in the first place. DHT, GH Deficiency, or just stress?

This is why it might be beneficial to work through an HRT Clinic.

These Hormonal Replacement Therapy clinics are not only able to prescribe you adequate meds for hair care, but they do so with a doctor looking over your blood work.

This means the actual problem will be fixed/treated and you will not just be firing into the dark.

There are retailers online where you can purchase certain Peptides or perhaps even the best peptides for hair growth, however, many of these need to be purchased under the nomenclature of “Research chemicals” and “not for human use”.

Peptides, for the most part, are legal substances, but their legality can vary based on their specific use and regulations in different regions. 

Peptides are often available for purchase online under the label of “research chemicals” or “not for human use.” 

This labeling is a legal precaution, as it implies that the peptides are intended for research or laboratory purposes rather than for human consumption. 

Many online vendors sell peptides with this disclaimer to comply with legal restrictions.

In many countries, certain peptides, especially those with potential medical applications, are regulated substances that require a prescription. 

To obtain these peptides legally, individuals typically need to consult with a healthcare professional who can assess their condition and prescribe the appropriate peptide treatment

This ensures the use of pharmaceutical-grade peptides and proper medical oversight.

Obtaining peptides through legitimate medical clinics or healthcare providers is often the safest and most legally compliant route. 

In such settings, patients receive prescriptions for peptides tailored to their specific health needs. 

This not only ensures the legality of the peptides but also provides the benefits of medical supervision and guidance.

While the purchase and use of peptides for research purposes are generally legal, their use for personal enhancement or performance enhancement purposes might fall into a legal gray area in some regions.

Conclusion: Are these Peptides worth it?

Absolutely. I have been struggling with hair loss for some time, and I was skeptical of these Peptides and Minoxidil. Yet, the best peptides for hair growth work.

The extent to which they work will depend on your growth cycle and how far down the road of hair loss you are.

Combined with hair care and making some lifestyle changes to get the best results, it certainly is worth it.

What causes Hair Loss?

More often than not the active growth phase will be downregulated by DHT-blocking hair follicles. They then reduce in size, causing hair thinning, and eventually, hair loss. Other factors influence hair growth such as Growth Hormone.

Natural ways to improve Healthy Hair Growth?

Living a healthy lifestyle, scalp massage, Vitamin E, Vitamin C, and making sure your hormones are in check

Do peptides block DHT?

Certain Peptides do, yes! Copper Peptides are remarkably good at this, as well as RU58841. You can also look at Finasteride.

BPC 157 Hair Growth?

There is some anecdotal evidence that BPC 157 could aid hair growth seeing as it will increase blood vessel count in the body.

Does copper peptide regrow hair?

Copper peptides not only play a significant role in regenerating new hair growth, but they can also make your existing hair look and feel thicker by increasing the follicle size.ย
