The price ladder, plainly
One pen is $119. Three pens are $299, which works out to about $99.67 per pen. Six pens are $558, or about $93 per pen. The first three pens carry a 90-day guarantee. There is no mystery bundle and no subscription math to decode: you can buy one pen, or buy a pack and lower the per-pen price. If you are testing whether a daily routine fits your household, start with one pen.
What one pen actually contains
Each pen holds 10 mg of BPC-157 and 10 mg of TB-500 in 3.0 mL, with 60 clicks total. One click is 0.05 mL, or about 167 mcg of each peptide. The weight sticker sets the click count: 1 click under 25 lb, 2 clicks at 25–60 lb, and 3 clicks Monday–Friday at 60+ lb. The pen is a 28-day use window from mixing, not a race to empty it. At 1 click a day, you will discard clicks at day 28; that is the design, not waste to fix.
The costs outside the pen
The pen price does not include a vet exam or diagnostics. CareCredit's 2025–2026 U.S. cost study lists a routine dog vet visit at $56–$129, arthritis testing at about $234 (about $410 with scans), and X-rays at about $172. Bloodwork, medications, rehab, and surgery are separate. These are estimates, not quotes; your clinic sets its own fees. Budget for the exam before you budget for the pen, because the diagnosis is the part that changes the plan.
How it compares with clinic-billed options
Librela is an FDA-approved monthly injection for canine osteoarthritis pain, billed by the clinic; there is no reliable national price, and PetMD notes that cost depends on weight and practice. CareCredit estimates arthritis NSAIDs at about $36 per month, steroids at about $36 per month, and joint supplements at about $33 per month. Those are not like-for-like comparisons: the pen is a research-use product, not a pain drug, and it does not replace any of them.
Is it worth it?
The honest answer is that you are paying for a fixed daily routine, not a proven cure. BPC-157 and TB-500 are research compounds, not FDA-approved veterinary drugs, and no controlled canine trials have established a benefit. If cost is tight, ask your vet about proven first-line options first: weight control, pain control, rehab, and a diagnosed plan. A pen is a support product for an owner who has already had that conversation, not a shortcut around it.

Is the pen cheaper than Librela?
That depends on your clinic's Librela quote. Librela is clinic-billed and varies with weight and practice. The pen is $119 per 28 days. They are different categories, so compare total monthly cost and the vet plan, not just the sticker.
What is not included in the price?
The vet exam, diagnostics, bloodwork, medications, rehab, and any procedures are separate. CareCredit's 2025–2026 study lists a routine dog visit at $56–$129 and arthritis testing at about $234.
Can I buy just one pen?
Yes. One pen is $119. The 3- and 6-pen packs lower the per-pen price, but you do not need a pack to start.
