Who are Peptides Sciences?

Peptide Sciences is a fully USA-run company producing and supplying some of the highest quality, USA made peptides on the market. They have an extremely scientific approach, which some might see as cold or distant, but when you’re administering these compounds to your body, I would prefer cold and calculated, over warm and woeful.

Whether your goal is to gain size, lose some fat, increase recovery, or just boost your longevity Peptide Sciences has you covered. Providing a massive array of products, and also providing a great amount of actual research on those products! What! A company that isn’t just about dollar signs but also educating the users – astounding.

Peptide Sciences has also negotiated with WHO/GMP and ISO 9001:2008 to enable them to manufacture high quality products at a cost effective price. But since peptides can mean so many things, let’s have a gander at what they offer:

Research Peptide Capsules

  • Fragment, CJC1295, Ipamorelin Blend

As a bonus, some of these products can be bought in bulk at a discounted price. As mentioned before, even if you aren’t the most clued up on peptides – they’ll provide you with tons of information on the frankly tons of options they have available.

How Does Science Peptides Work?

Science Peptides is a company that really reflects what the name reads – scientific. A great amount of effort goes into research and execution for a great product. They are extremely meticulous on their quality, and what they produce. The only real downside, is the fact that they do not offer returns on products. Regardless of this, for what they offer at the price is something really worth looking into.

Best Science Peptides Products

Obviously it’ll be impossible for me to list all of the great products they provide, but here are just some of my favorite ones:

CJC-1295, GHRP-6 10mg (Blend)

Peptide Sciences Review

As I mentioned in my article on How to use Peptides for Bodybuilding, combining a Growth Hormone Releasing Hormone (GHRH – CJC-1295) with a Growth Hormone Releasing Peptide (GHRP – GHRP-6) massively increases the benefits of both. They provide an aptly dosed combination of the two. Nice.

IGF-1 LR3 1mg

Peptide Sciences Review

IGF (Insulin Growth like Factor) is really a game changer when used correctly. With effects not only in muscle mass increase, but also fat loss – a great product all around. The LR3 version is the lengthened analogue of the IGF-1, and requires less frequent dosing, hard to find.

hGH Fragment 176-191 10mg

Peptide Sciences Review

10mg?? Nice. hGH Fragment 176-191 (or Frag) is one of the best fat loss peptides on the market today. A fragment of hGH (duh) and can accelerate lipolysis greatly.

Ordering and Shipping

Payment options are always a hot topic of contention. Luckily Peptide Sciences has you covered with various options:

  • Apple Cash
  • Cash App
  • Zelle
  • Crypto (Eth, Bitcoin)
  • Credit Card

Shipping is a flat rate $15 for all USA orders, with a timeline of around USPS 2-3 day via Priority Mail. All USA orders include free shipping if the amount is over $200. International orders (obviously) are around 7-10 business days. To go even further, they offer other shipping options, including but not limited to overnight shipping, FedEx, and FedEx Saturday delivery. As mentioned before, they do not offer a return service due to the nature of the products being sold.


Science Peptides doesn’t actually have a review section on their site. So, when all fails go to the newspaper of the internet: Reddit.

Reddit username “fastwater” said this about them one year ago:

“I have also been using Peptide Sciences products for several years because the results have been very good for me. That’s all that really matters as far as I am concerned. My rotator cuff tear (confirmed on MRI) improved by about 80% in 2 weeks with an aggressive 2x’s/day protocol of their BPC157 and TB500 (separates, not blend). Previous to starting the peps my Ortho saw my MRI and told me I would need arthroscopic surgery to repair the tear but I did not go that route. It’s not the prices of the products I am so concerned about, its the quality and effectiveness. I have tried many other peptide companies with little to no results. I have not yet tried CanLabs but I hear positive comments. The only other significant results I got was from Tailor Made’s products. Since the issues they had, I went back to PS. My results speak for themselves no matter what anyone else says. “

Pretty strong stuff.

Reddit username “rbegui” had this to say about them one year ago:

“i disagree with some of the comments on PS. I have used them for years without any problems whatsoever. I have tried other cheaper suppliers and have not had the same experience. For example: I have tried Sermorelin from a couple of other suppliers and had problems with injection site redness and stinging, never had that with PS. Its comparable with the prescription stuff I was paying $300 per month TB500/BPC157, I can feel the PS product working on my tendons and ligaments, I have not experienced this with other suppliers (notably blue sky). PS claims there stuff is made in the USA, I’ve never investigated that, but as so many things in life. “you get what you pay for” “

Seems to me that the reviews are nothing but glowing!


Science Peptides vs Pure Rawz

First off, Science Peptides only does peptides whereas Pure Rawz does peptides, SARMs (Selective Androgen Receptor Modulators) and other products. This might be seen as a bad thing, I disagree. This just confirms Science Peptides’ assertiveness in the peptide game for myself.

Price wise, Science Peptides does provide massive savings, not just in gross price, but also in bulk purchase options.

Science Peptides vs Swiss Chems

Again, Science Peptides specializes in peptides alone, whereas Swiss Chems dabbles in other products including SARMs, PCT products, and male enhancement products. Swiss Chems offers money back guaranteed, but Science Peptides has more testing done on their products. Swiss Chems is cheaper, but Science Peptides has a much larger variety. Close call really.

Science Peptides vs Chemyo

Science Peptides really focuses on giving a variety and high quality peptides, and only peptides. This leaves them in a situation where a company like Chemyo can swoop in with a greater variety of products such as SARMs and Nootropics, however Science Peptides has way more peptide options.

1. Where is Science Peptides located?

Henderson, Nevada, United States

2. Is it legal to buy peptides online?

It is illegal to purchase peptides for human usage or to buy peptides that are not labeled as “research chemicals”.

3. Are their products tested?

Yes. They provide various images of test results on most of their products, and their site does read that they have negotiated with WHO/GMP and ISO 9001:2008 to enable them to manufacture high quality products.


Science Peptides really does not over promise to underdeliver. They claim to be scientific and they are. With a great range of products, competitive pricing, and a massive amount of payment and shipping options they are a great peptide source. The only real drawback is the fact that you cannot return products.

  1. Holy shit. I try to leave a comment and that ad keeps getting in the way. WHO/GMP is meaningless. It’s not the world health organization. It’s some cheap India knockoff. Ben Greenfield has a link to a report from some govt agency that showed about 70 percent of the tested products were legit but the others total bunk. Not a track record I eant to subject my rat to.

  2. How to you justify selling this to consumers when there are not the regulations in place to verify safety in humans and all their labels clearly say “Not for Use in Humans or Animals.” Further, they sell Semaglutide, which is controlled as a prescription, along with all other peptides with 0 info on dosage, side effects or warnings. How much were you paid off for this?? CONSUMER BE AWARE of this company and all their reviews.

  3. I have been using Science Peptides for years. I’m a 60 year old male and I will be using this company for years to come.
