Who Apollo Peptide Sciences is, and who it is not

The first thing to settle is the name, because it confuses a lot of buyers. Apollo Peptide Sciences is not the original "Peptide Sciences." It is a separate, newer vendor that emerged after the original company shut down, and it has captured much of that defunct brand's search traffic rather than continuing the original business. If you searched "peptide sciences tirzepatide" and landed on Apollo, that is why.


We are not going to re-tell the closure story here. If you want the background on why the original vendor disappeared and what it meant for the grey market, read our breakdown of the Peptide Sciences shutdown. The short version for this page: treat Apollo as a vetted alternative for people who came looking for the old name, not as a revival of it.

The GLP-1 and incretin lineup

This is the core of Apollo's catalog and the reason most people find it. The lineup centers on the incretin family, the gut-signaling compounds that have driven the recent wave of metabolic research peptides. Apollo carries semaglutide under its in-house "GLP-1S" label, tirzepatide as "GLP-2T," and retatrutide as "GLP-3R." The naming convention is proprietary to Apollo, so do not read those codes as standardized industry terms.


We do not cover how these compounds work, what they do in the body, or any weight-related outcome on this page, because that is education, not sourcing. For the science, see our guide to GLP-1 agonists like semaglutide and tirzepatide and the separate look at GLP-1 safety considerations around gallbladder and pancreatitis risk.


What we can point to is a concrete proof point. Apollo's published testing on a recent tirzepatide lot (batch P525111L, April 2026) returned a purity result of 99.859%. A single batch is not a guarantee of every future vial, but a near-99.9% result on a flagship compound is a strong data point for an emerging vendor.

Quality and third-party testing

Janoshik COA for Apollo Peptide Sciences Tirzepatide 15mg showing 99.799% purity

Apollo runs third-party testing through Janoshik, an independent analytical lab widely used in the research peptide space. Every batch is tested by HPLC, which is high-performance liquid chromatography, the standard method for measuring how much of a sample is the intended compound. Results carry a QR code and a verification key, and recent lots clear a baseline of 98% or higher, frequently landing at 99%+.


One detail worth crediting: the testing is blind. The manufacturer is submitted to the lab as "Unknown," which removes a path for the lab to bias a result toward a known client. Apollo also reported generous fill on at least one product, with 25.48 mg measured in a vial labeled 20 mg, an overfill of about 127%.

Now the honest scope, because this is where a lot of vendors get a free pass they should not. Apollo's documented testing covers purity only. There is no published sterility, endotoxin, microbial, or mass-spectrometry panel, and public batch-level access to the full certificate of analysis is unconfirmed. Purity tells you what fraction of the powder is the right molecule. It does not tell you whether the material is sterile or free of bacterial byproducts. Before you trust any supplier's numbers, it helps to understand what third-party testing actually covers and what to look for in a COA.

The rest of the catalog

Beyond GLP-1s, Apollo stocks a standard research catalog rather than a deep specialty shelf. Recovery staples like BPC-157 and TB-500 are there, alongside GHK-Cu, NAD+ at 500 mg, CJC-1295 with Ipamorelin, SNAP-8, IGF-1 LR3, and Epithalon. There is no bioregulator depth and there are no proprietary blends. If your interest is one of these compounds rather than a GLP-1, Apollo is a reasonable stocking option, but it is not where the vendor differentiates itself.

Research-only positioning and compliance

Apollo labels and sells everything as research-use-only material. It provides no dosing or administration guidance, and it is not a 503A or 503B compounding pharmacy. That distinction matters for both legality and accountability. If you are unclear on the line, read what the research-only label actually means and how that differs from compounding-pharmacy peptides, which operate under a separate regulatory framework.


Handling, reconstitution, and storage

Apollo ships lyophilized vials, meaning the peptide arrives freeze-dried as a powder. You reconstitute it with bacteriostatic water, then keep it cold and dry, with a typical use window of four to six weeks when stored at 36 to 46°F. Getting the reconstitution math right is where most errors creep in, so run your vial through our free Peptide Calculator for exact figures before you mix. →

Apollo Peptide Sciences shipping and delivery


Apollo packs and ships six days a week, Monday through Saturday, from a domestic US operation. Saturday dispatch is unusual in this category and it is the detail that matters if you order late in the week, because a Friday afternoon order at most suppliers sits until Monday.


Rates, the free-shipping threshold, cutoff times and the returns position are on the Apollo Peptide Sciences coupon code page.


For researchers, this means Apollo suits planned GLP-1 and peptide projects rather than last-minute or highly time-sensitive runs.

Apollos Limitations and what to verify

A fair review names the weak spots plainly, and Apollo has several.


Testing is purity-only. Strong HPLC numbers, but no published sterility, endotoxin, or microbial data. Little independent validation. There is no meaningful Reddit, Trustpilot, or Finnrick history yet to corroborate the brand's own claims. New and low-traffic. Apollo is an emerging vendor, so longevity, consistency, and customer-service patterns are still unproven. Heavy aggregator footprint. The brand shows up across coupon sites, which inflates visibility without adding trust signals. Name confusion. The overlap with the defunct Peptide Sciences brand can mislead buyers who assume continuity that does not exist.


None of these is automatically disqualifying. Together they explain why Apollo earns a solid-but-cautious score rather than a top one.


Verdict

Apollo Peptide Sciences earns 2.9 out of 5, a Standards Score of 37 out of 100.


If those gaps are acceptable for your purposes, the purity data is among the better signals in this category.


Apollo is one option among several vetted suppliers, so it is worth comparing its purity-only testing against vendors that publish broader panels before you commit. See how it stacks up in our full Vendor Directory.

Apollo Peptide Sciences FAQ

  • Is Apollo Peptide Sciences legit?

    Apollo Peptide Sciences shows the signals researchers use to vet a source: every batch is tested by Janoshik, an independent analytical lab, using blind HPLC purity analysis, and recent lots have returned 99%+ purity with QR-verifiable certificates. The main caveats are that its published testing covers purity only, not sterility or endotoxins, and the brand is new with a short independent track record. It looks legitimate for verified-purity research sourcing, weighed against those gaps.


  • Is Apollo Peptide Sciences the same as the original Peptide Sciences?

    No. Apollo Peptide Sciences is a separate, newer company that launched after the original Peptide Sciences shut down. Despite the similar name, it is not a continuation of that brand and shares no verified corporate lineage with it, so it should be judged on its own testing and track record.


  • Who does the third-party testing for Apollo Peptide Sciences?

    Testing is performed by Janoshik, an independent third-party analytical laboratory widely used across the research peptide market. Apollo submits samples for blind HPLC purity analysis, meaning the manufacturer is listed to the lab as "Unknown" so the result cannot be influenced by the brand. Each certificate is QR-coded with a verification key so buyers can confirm it is genuine.


  • What purity does Apollo Peptide Sciences report?

    Recent Apollo lots report 98%+ purity and frequently exceed 99%. Documented examples include a Tirzepatide batch (P525111L, April 2026) at 99.859% and a separate Tirzepatide 15mg certificate at 99.799% with 17.13mg measured content. Purity is verified by HPLC through Janoshik; sterility, endotoxin, and microbial panels are not currently published.


  • What does Apollo Peptide Sciences sell?

    Apollo specializes in GLP-1 and incretin research compounds, including semaglutide, tirzepatide, and retatrutide, sold under in-house labels (GLP-1S, GLP-2T, and GLP-3R). The broader catalog also carries BPC-157, TB-500, GHK-Cu, NAD+ 500mg, CJC-1295 with Ipamorelin, SNAP-8, IGF-1 LR3, and Epithalon. All products ship as lyophilized vials strictly for laboratory research use.


  • Does Apollo Peptide Sciences sell tirzepatide, semaglutide, and retatrutide?

    Yes. All three GLP-1 class compounds are in the Apollo lineup under in-house labels, with recent Janoshik purity certificates available for the GLP-1 range. They are sold strictly as research-only material, and Apollo provides no dosing or administration guidance.


  • What are the limitations of Apollo Peptide Sciences?

    Two limitations stand out. First, published third-party testing through Janoshik covers purity only, with no sterility, endotoxin, microbial, or mass-spectrometry panels released. Second, Apollo is a new vendor with little independent community history on Reddit, Trustpilot, or Finnrick, so most available signal comes from its own certificates rather than long-term user reports. These are the reasons the Project Biohacking editorial rating sits at 3.0 out of 5.


  • Are there Apollo Peptide Sciences reviews on Reddit?

    Independent community feedback on Apollo is still thin. Because the brand is new, it has little established discussion on Reddit, Trustpilot, or Finnrick, so the strongest available evidence is its published Janoshik purity testing rather than a long history of third-party user reports.


  • Is Apollo Peptide Sciences a compounding pharmacy, or safe for human use?

    No. Apollo sells strictly research-use-only material and is not a 503A or 503B compounding pharmacy. Its products are not approved for human or veterinary use, and Apollo provides no dosing or administration guidance. Nothing on this page is medical advice.


  • How do you store Apollo peptides after reconstitution?

    Apollo ships lyophilized (freeze-dried) vials that are reconstituted with bacteriostatic water for research handling. After reconstitution, vials are kept cold and dry, with a typical working window of four to six weeks when stored at 36 to 46 degrees Fahrenheit. Unreconstituted lyophilized powder stays stable far longer when kept frozen.
