Peptides Sold by Blue Sky Peptide

The Blue Sky Peptide catalog includes various research chemicals and peptides. These are the top 3 peptide products available on the site:

Blue Sky Peptide BPC-157

Also known as Body Protection Compound-157, this synthetic pentadecapeptide is derived from BPC, an organic compound that is present in human gastrointestinal fluid. A potent angiogenic, BPC heals, protects, and calms the gastrointestinal lining for healthy functioning [1]. Research indicates the peptide’s safety and potential in various therapeutic contexts, such as addressing symptoms of inflammation, fostering muscle and tendon growth, protecting the nervous system, and improving injury recovery [2, 3, 4, 5].

Blue Sky Peptide TB-500

A synthetic analog of thymosin-beta 4, this angiogenic peptide modulates actin levels to foster cellular regeneration in most animal cells [6]. It is currently being studied for potential therapeutic benefits that include combating symptoms of cardiovascular disease, promoting the healing of injuries, countering inflammatory symptoms, and anti-aging effects [7, 8].

Blue Sky Peptide Melanotan 2

Also called MT-2, this peptide is a synthetic version of alpha-melanocyte-stimulating hormone (α-MSH). It acts on melanocortin receptors to varying outcomes, including melanogenesis, addressing symptoms of sexual dysfunction like ED, and improving physical composition. To date, it has a favorable safety rating when handled by qualified researchers [9, 10, 11].

The selection also includes the α-MSH derivative PT-141. Plus, anti-aging peptides like SNAP-8 and epithalon are available, as well as potent GH secretagogues like:

Benefits of Buying from Blue Sky Peptide

Blue Sky Peptide has some notable strengths, such as the following:

Third-Party Lab Test Results Available to Verify Quality Claims

To assure the quality of its products, Blue Sky Peptide displays third-party lab test results alongside peptide and chemical listings. Available test results include Mass Spectrometry and UV analyses to demonstrate the correct identity and high purity levels of the compounds. The reports appear to be legitimate and valid, including lab information and recent test dates.

Variety of Peptides and Chemicals

Blue Sky Peptide carries a range of research chemicals and peptides. Chemicals include SARMs and various other classes, while peptides range from growth hormone secretagogues to anti-aging compounds.

Easy and Secure Checkout

Payment and shipping options are clearly defined before checkout for a smooth customer experience. The protection of client financial data is assured through SSL encryption technology.

Low Prices With Regular Discounts

Available products are competitively priced and subject to regular deals such as buy one get one free and price cuts of up to 45%. The vendor also offers comprehensive price breaks on bulk purchases. Enrollment in the BSP Rewards program can also earn sizable price cuts for regular clients.

Shipping Speed Options and International Deliveries

Blue Sky Peptide offers a range of shipping speeds with conveniently low flat fees on domestic orders. Plus, clients from around the world can receive orders with the availability of international shipping options, also available at express rates.

Downsides of Buying from Blue Sky Peptide

While Blue Sky Peptide has some appealing qualities, we have noted several drawbacks. Here are the primary issues that we observed:

Lab Testing Methods do Not Meet the Leading Standards

The retailer claims to conduct third-party quality assurance tests that include Mass Spectrometry and High Performance Liquid Chromatography analyses, the most accurate methods according to pharmacological experts [12].

However, the test results provided show only Mass Spectrometry and UV analyses. The discrepancy is concerning, as well as the fact that UV analysis is known to be a less accurate and lower-cost alternative to HPLC analysis [13]. This opens the possibility of erroneous quality reports, which, particularly regarding SARMs, could raise safety concerns [14].

Persistent client reviews of low-caliber products, in addition to markedly low prices, tend to affirm this quality concern.

Limited Product Forms Are Available

The vendor’s leading competitors provide research peptides and chemicals in a range of forms, from liquids and topicals to powders and capsules. However, the Blue Sky Peptide selection is restricted to powder peptides and liquid research chemicals.

Mixed Reviews That Cite Significant Concerns

A survey of client reviews on independent forms yields mixed reviews. Many clients are dissatisfied with the product quality. Further, reviews from 2021 and earlier cite test results that lack dates or company names, and are incorrectly labeled. Observers noted that when tests included information, it often indicated lab sites outside of the USA.

While the vendor has taken steps to rectify this, now providing test results with the required information from domestic partners, its uneven track record does not inspire confidence.

Lack of Payment Options

With only three payment methods accepted, Blue Sky Peptide is lacking compared to other retailers who accept numerous traditional and alternative payment methods. The available methods are also subject to restrictions, adding further inconvenience for some clients.

Unremarkable Website and Minimal Online Presence Despite Almost Ten Years In Business

Though the Blue Sky Peptide website is not as problematic as some we’ve seen, it leaves room for improvement. In addition to the discrepancies noted above regarding its quality assurance claims, its product listings don’t provide user-friendly information on the chemical properties and potential applications. Chemical descriptions are not required, but small write-ups are a convenient feature that many other retailers offer.

Plus, given that Blue Sky Peptide was founded in 2013, we might expect a more substantial online presence. However, the website links to social media sites with few followers and no user activity in the past few years.

Blue Sky Peptide Reviews from Customers

Don’t take our word for it! Let’s take a look at what some customers of Blue Sky Peptide have to say about the company:

Blue Sky Peptide has certainly satisfied some of its clients. Check out this positive review:

“My go-to research chemical and peptide company. I'm a fan of the frequent discount codes and their buy 2 and get 1 free offers. They also have a rewards program that allows customers to accumulate points with purchases that can be redeemed for gift certificates… I received my order within 3 days of payment. Industry-standard packaging with no indication of contents. Plenty of bubble wrap used to protect contents.” [15]

However, many clients have not had satisfactory experiences:

“I have used Blue Sky for years with no problems. About a month ago I made an order and after a week still no tracking. After multiple emails they finally responded asking for my bitcoin transaction receipt. I sent the info and after another hand full of emails nothing. No answer on their telephone number either. They have gone scammer…stay away.” [15]

Is Blue Sky Peptide Legit?

Blue Sky Peptide is not a fully legit choice for online research chemical and peptide purchases. Though it is not the worst we’ve seen, there is significant room for improvement. The body of evidence from its nearly ten-year track record paints an uncertain picture. Here are the main reasons we can’t definitively recommend Blue Sky Peptide as a legit source:

  • Concern over validity and accuracy of third-party test results
  • Limited product formats
  • Limited payment options
  • Mixed reviews with repeated claims of poor service, low quality, and historical inconsistencies
  • Substandard website and no current social media

Researchers are much better off with a proven and reputable source. Read on as we detail our top alternative vendor.

Blue Sky Peptide Review | Verdict

To summarize, Blue Sky Peptide is not the best option for guaranteed satisfaction when buying research peptides online. We appreciate its strong points, such as evidence of third-party quality assurance testing, regular discounts, and international shipping options. However, there is some doubt over the validity of its available test results.
