Two injections that share the name PRP can be very different treatments. The difference is measurable. The dose: research ties results to the total platelet dose, yet many bedside kits produce only a 2 to 3 times concentration. The preparation: single-spin versus multi-spin, with or without fibrin and exosomes. The physician: the doctor who diagnosed you, or a technician. The placement: live-ultrasound targeting versus a blind injection. Our Dynamic PRP+ protocol concentrates platelets 12 to 20 times baseline, over 10 billion, placed under live ultrasound by Aneesh Garg, DO, CAQ. Same acronym. Not the same medicine.
A physician-written explanation of why identical-sounding PRP injections produce different results, and how to tell protocol-grade PRP from a commodity shot.
The decision
The word PRP describes a category, not a recipe. More than forty commercial systems exist, each producing a different platelet count, white-cell content, and volume. That is why one patient calls PRP life-changing and another calls it a waste. They did not receive the same treatment.
So the real decision is not whether to try PRP. It is which PRP, made how, placed where, and by whom. This page breaks the difference into four things you can verify. If you want the full picture of the treatment itself, see our overview of PRP therapy in Boulder.
Key takeaways
- PRP is a category, not a standard. A 2017 review in The Journal of Bone and Joint Surgery called for standardization because clinics rarely report what they inject.
- Total platelet dose drives results. Under-concentrated, over-split preparations deliver a diluted dose. Dynamic PRP+ concentrates platelets over 10 billion, 12 to 20 times baseline.
- Preparation is where PRP stops being one thing. A single-spin bedside kit differs from multi-spin PRP paired with Fibrin-Rich Plasma and exosomes.
- Who holds the needle matters. Dynamic PRP+ is performed exclusively by Aneesh Garg, DO, CAQ, who trains other physicians on biologics, never delegated to a technician.
- Placement decides whether the dose reaches the tissue. Live ultrasound targets the injury; a blind injection relies on feel.
- In our Dynamic PRP+ protocol, over 90% of our patients self-report a 75% or greater improvement, all without surgery.
Four things that make two PRP shots different treatments
Each variable below is one you can confirm before you decide. Your result is the sum of all four.
The dose: what is actually in the syringe
PRP works by concentrating your own platelets, so the number of platelets delivered is the treatment. The evidence points one way: higher, well-characterized doses tend to outperform low-dose preparations. The common shortfall is a small draw, spun once and split across several sites, so each target gets a diluted dose. Dynamic PRP+ uses a larger draw and multi-spin processing to concentrate platelets over 10 billion, 12 to 20 times whole-blood baseline, against the 2 to 3 times many bedside kits produce. The number is the medicine.
The preparation: how it is made
Preparation is where two injections sold as PRP become different treatments. Single-spin versus multi-spin, leukocyte-rich versus leukocyte-poor, and the final platelet yield vary between clinics, and most never measure or report them. Dynamic PRP+ pairs high-dose PRP with Exosome-Containing Fibrin-Rich Plasma, a scaffold that helps hold the biologics at the target instead of letting them wash away. A commodity injection is whatever a countertop kit yields in one spin. A protocol is tuned to the tissue.
The physician: whose hands hold the needle
At many clinics the diagnosis, the imaging, and the injection are split across different staff, so the hands placing the needle never examined the problem. Every Dynamic PRP+ procedure is performed exclusively by Aneesh Garg, DO, CAQ, “The Regen Doc,” who diagnoses, plans, and injects personally. He is a double board-certified physician, Yale-New Haven trained, an Andrews Sports Medicine fellow, and teaching faculty at the Regenerative Medicine Training Institute, where he trains other physicians on biologics.
The placement: where the injectate lands
Even a perfectly prepared syringe does nothing if it lands in the tissue next to the injury. Live ultrasound lets the physician watch the needle tip reach the exact target, confirm the injectate spreads where intended, and avoid nearby nerves and vessels. A blind injection relies on surface anatomy and feel. That is whether the dose reaches the problem at all.
Commodity PRP or protocol-grade PRP: what to verify
- What is the total platelet dose, and how many times is the blood spun?
- Is the preparation tuned to my condition, or one countertop spin?
- Will the injection be placed under live ultrasound?
- Will the physician who diagnosed me perform the injection?

The one line to remember
A commodity PRP shot and a protocol-grade one can look identical on paper and share the same three letters. The difference is the dose, the preparation, the imaging that places it, and the physician who performs it. When those four align, PRP has a real evidence base for the right patient. When any one is missing, the injection can be completed and still do nothing.
Frequently asked questions
Why is high-dose PRP different from standard PRP?
PRP works by concentrating the platelets in your own blood and delivering them to an injury, so the total number of platelets you receive is central to the result. Standard or bedside PRP is often a single spin that yields a 2 to 3 times concentration above whole-blood baseline, and that dose can be diluted further when a small draw is split across several injection sites. High-dose PRP, like our Dynamic PRP+ protocol, uses a larger draw and multi-spin processing to concentrate platelets 12 to 20 times baseline, over 10 billion, so the target tissue receives a therapeutic dose rather than a diluted one. The direction of the orthopaedic evidence favors higher, well-characterized doses. Same name, different medicine.
How many platelets should a PRP injection contain?
There is no single universal number that fits every joint and tendon, but the research has moved decisively toward total platelet dose as the variable that matters, measured in billions of platelets delivered rather than a vague concentration multiple. Preparations that fall short of a therapeutic dose are more likely to underperform, while higher, well-characterized doses tend to produce better and more durable results for orthopaedic indications. The practical problem is that most clinics never measure what they inject, so patients cannot compare. Our Dynamic PRP+ protocol concentrates platelets to over 10 billion, 12 to 20 times whole-blood baseline. Ask any clinic directly how many platelets you will receive. A clinic that treats PRP seriously can answer.
What is commodity PRP?
Commodity PRP is the version produced by a countertop kit in a single spin, drawn and injected as a routine add-on rather than a planned protocol. It is not necessarily harmful, and for some minor problems it may be enough, but it is defined by what it leaves unmeasured: the platelet dose is rarely counted, the preparation is not tuned to the specific tissue, the injection is frequently placed by feel rather than imaging, and it is often delegated to a technician. Two clinics can both bill the injection as platelet-rich plasma while delivering very different treatments. Protocol-grade PRP is the opposite: a measured dose, a preparation matched to the target, live-ultrasound placement, and a physician who diagnosed you performing the injection.
Does the concentration of PRP actually change outcomes?
Yes, the composition and dose of PRP influence outcomes, which is why leading orthopaedic journals have called for clinics to standardize and report what they inject. A 2013 randomized trial in The American Journal of Sports Medicine found PRP more effective than placebo for knee osteoarthritis, and a 2021 study in Scientific Reports specifically identified platelet dose as critical to durable knee results. A 2017 meta-analysis in the same journal supported PRP for tendinopathy. None of this makes PRP universally effective; it makes preparation, dose, diagnosis, and placement the variables that decide whether a given patient benefits. That is exactly why a low-dose, blind, delegated injection and a high-dose, ultrasound-guided, physician-performed one are not the same treatment.
Is PRP performed by a physician better than PRP done by a technician?
The person who diagnoses you should be the person injecting you. Regenerative results depend on an accurate diagnosis, the right target, and precise placement, and those judgments are hard to delegate. At many clinics the evaluation, the imaging interpretation, and the injection are handled by different staff, so the hands placing the needle never examined the problem. At Dynamic Athlete, Aneesh Garg, DO, CAQ, “The Regen Doc”, performs the diagnostic ultrasound, selects the target, prepares the plan, and performs the injection personally. He is a double board-certified physician who trains other physicians on biologics at the Regenerative Medicine Training Institute. Before booking anywhere, ask a direct question: will the physician who diagnoses me also perform my injection, or is it delegated.
What is Dynamic PRP+?
Dynamic PRP+ is our high-dose platelet-rich plasma protocol. It uses a larger blood draw and multi-spin processing to concentrate platelets 12 to 20 times whole-blood baseline, over 10 billion, and pairs them with Exosome-Containing Fibrin-Rich Plasma, a scaffold that helps keep the biologics at the target. Every step is performed by Aneesh Garg, DO, CAQ, under live ultrasound guidance, so the diagnosis, the target selection, and the placement are handled by one physician. When PRP alone is not the right tool, the same evaluation can escalate to bone-marrow or adipose-derived cellular therapy. It is designed as a planned treatment matched to your specific injury, not a routine add-on injection produced by a countertop kit.
Where can I get high-dose, physician-performed PRP in Boulder?
Dynamic Athlete Sports Medicine and Regenerative Orthopaedics in Boulder provides high-dose, physician-performed PRP under live ultrasound guidance. Aneesh Garg, DO, CAQ, “The Regen Doc”, personally performs the diagnostic evaluation and the injection using the Dynamic PRP+ preparation, and can escalate to bone-marrow or adipose-derived cellular therapy when PRP alone is not the right tool. He founded the American Shockwave Training Institute and is teaching faculty at the Regenerative Medicine Training Institute and Rocky Vista University, where he trains other physicians on biologics. The clinic serves Boulder, Louisville, Lafayette, Erie, Broomfield, Longmont, and the surrounding Front Range. A consultation begins with finding the true source of the problem, then matching the protocol to it, rather than selling a single injection to everyone.
