Peptides Sold by USA Peptide

The top 3 peptides from USA Peptide are:

USA Peptide BPC-157

BPC-157 is a pentadecapeptide derived from Body Protection Compound, which is naturally present in the GI tract. A potent angiogenic, it protects and heals the gastrointestinal lining and is key to healthy GI function [1]. Studies have shown its therapeutic potential in improving injury recovery, neuroprotection, and tissue growth stimulation [2, 3, 4]. At present, it has a high safety rating [5].

USA Peptide TB-500

TB-500 is a synthetic derivative of the organic thymosin-beta 4 protein, an angiogenic which upregulates actin and boosts cellular regeneration in animal cells [6]. Research indicates its potential to treat symptoms of cardiovascular and inflammatory diseases and improve injury recovery. It may also have anti-aging benefits and is considered safe for handling by qualified professionals [7, 8].

USA Peptide Melanotan 2

Melanotan 2 (MT-2) is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH). The peptide works to activates melanocortin receptors to darken skin tone, treat symptoms of male erectile dysfunction, improve sexual arousal, decrease appetite, and modify autistic behavioral patterns. It also potentially improves body composition and has a favorable safety rating [9, 10, 11].

USA Peptide also carries the α-MSH derivatives Melanotan 1 and PT-141.

Its selection of anti-aging peptides includes GHK-Cu, Argireline, and SNAP-8.

The vendor’s selection of potent growth hormone secretagogues features:

Payment and Shipping

Payment options are limited and do not inspire confidence. While the website indicates that it uses SSL encryption, many client reviews cite breaches of security and unsatisfactory payment practices.

USA Peptide does not accept debit or credit cards. Payment options are restricted to several alternative methods, most listed with dubious disclaimers that the client is to treat the transaction as a personal payment and omit product information. Some of the payment options involve having to send money to personal email addresses and private individuals. Accepted methods include:

  • Klarna
  • Zelle (linked to a personal email)
  • Cash App
  • Google Pay (linked to a different personal email)
  • Venmo (to a private user)
  • Walmart2Walmart (to a private individual)
  • Bitcoin
  • Electronic Check

The shipping details are as follows:

  • Exact shipping times and rates only available at check-out
  • Deliveries within the USA typically arrive within 2-3 business days
  • An expedited domestic shipping option of 1-2 business days is available
  • International deliveries typically arrive within 4-7 business days
  • Most deliveries are done via the US Postal Service with tracking
  • Domestic and international shipping insurance plans are available for purchase

USA Peptide does not accept returns but offers guarantees on lost or damaged parcels with the purchase of an insurance plan. The site is linked to a third-party loyalty rewards service that issues discount coupons for enrolled clients.

Benefits of Buying from USA Peptide

There are a few upsides to buying from USA Peptide, such as:

Variety of Products

USA Peptide’s selection includes a satisfactory range of product types, including numerous research peptides and blends in powder form. The research chemical catalog includes various SARMs, nootropics, and more. Several types of research solvents are also available, in addition to vials, syringes, and assorted lab supplies.

Educational Product Information for Some Items Available on the Website

Many products on the website are presented with in-depth descriptions of the compounds’ chemical properties and potential therapeutic applications.

Pricing Incentives

USA Peptide provides regular discounts on various products, as well as discounts on bulk purchases. Discount coupons are available, including those issued through the third-party customer rewards program. Certain payment options also garner small price reductions at check-out.

Rapid Shipping with Tracking Available

The site advertises relatively quick domestic shipping with package tracking available through the US Postal Service.

Downsides of Buying from USA Peptide

While there are some high points of shopping with USA Peptide, there are numerous downsides. The drawbacks include the following:

No Claims or Assurance of Quality on Any Products

The vendor's website provides no information on the quality or manufacturing of its products. There is no indication of testing for product safety or purity, and the site includes a lengthy disclaimer that absolves the vendor of all responsibility in these areas [12, 13]. Further, peptides are limited to powder form.

Unclear Product Origins

Despite the company name and American headquarters, USA Peptide provides no information on the manufacturing location of its products. This suggests that the materials are probably sourced in countries that lack quality control measures in comparison to US standards.

Poor Independent Customer Reviews

Though the vendor website includes numerous reviews, their unanimous positivity calls their authenticity into question. Client reviews from outside sources are almost unanimously negative regarding customer service, payment practices, and product quality.

Limited Payment Options with Questionable Disclaimers

This vendor does not accept standard methods of payment and instead offers a small number of alternative methods. Most methods include prominent warnings that clients should not include product information and in fact, should treat purchases as personal payments. Further, many payment options are directed not to the company, but various private individuals.

Lack of Clear Chipping Rates, Delivery Assurance, or Information on Shipping Providers

Shipping rates are not clear to clients until check-out. While the vendor names the USPS as one possible delivery service, it indicates that other services may be used. Further, there is no assurance of safe delivery without the purchase of the vendor’s private shipping insurance packages.

USA Peptide Reviews from Researchers

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

A satisfied contributor to a peptide vendor review forum said this:

“USA Peptide are a genuine company that offers good service, outstanding products, and a helpful customer service department.” [14]

However, this negative client review on another trusted forum echoed many others:

“I sent payment via Venmo 5 days ago and my order says it is still being prepared for shipping. I have received no responses from emails regarding the shipment either…The lack of communication and other reviews from this site lead me to believe this site is either a scam, or has an extremely inefficient business practice which makes the buyer feel like he is being scammed. I would strongly advise you to [be] wary before placing an order with them.” [15]

Is USA Peptide Legit?

USA Peptide is not a recommended online vendor of research chemicals and peptides. The company does not fulfill the criteria put forth by experts for identifying a reputable source. Here are the specific areas of concern:

  • No product testing or quality control regarding safety or purity
  • No information on product origins or manufacturing
  • Accepts only a small number of alternative payment methods with unprofessional business practices
  • Trend of negative client reviews regarding customer service, business practices, and product quality

Additionally, the company website is of poor quality, including numerous spelling errors, and there is no significant online presence or social media content. Although the company website lists a few email addresses and phone numbers for customer service inquiries, most customer reviews cite a lack of response.

USA Peptide Discount Code

The company website lists this code: SPRINGISSPRUNG

Are Peptides Legal?

Yes. Research peptides are fully legal when handled by qualified professionals.

Are Peptides a Steroid?

No. While anabolic steroids have androgens, peptides do not. The two are distinct classes of chemicals.

Where Does USA Peptide Produce Their Products?

This is unclear.

Does USA Peptide Test Their Products?

No. USA Peptides does not indicate that it tests its products.

USA Peptide Review | Verdict

In conclusion, we do not recommend USA Peptide as an online source for research chemicals and peptides. Although it does have a conspicuous range of peptides, SARMs, and chemicals including nootropics, there is no discernable testing or quality assurance on any available products.

While the vendor’s pricing is reasonable and includes frequent discounts, bulk price breaks, and coupons, the payment and shipping details do not inspire confidence. The myriad of negative client reviews supports our poor impression of this company.

Instead, opt for a reputable name, such as Limitless Life, the leading peptide source for the scientific community.
