bpc-157 dose for dogs by weight: the click chart

the pen doses by weight band — 1, 2, or 3 clicks daily, not a milligram table. what each click carries, how the 28-day window works, and why your vet confirms the band.

here is the chart — for The Dog Peptide Pen specifically, not for bpc-157 in the abstract. under 25 lb: 1 click, once daily. 25–60 lb: 2 clicks, once daily. 60+ lb: 3 clicks monday–friday. the 28-day use window starts when the pen is mixed. that is the whole schedule. it is a fixed delivery protocol for a research-use product, not a universal veterinary dose, and your vet should confirm the band before the first click.

why clicks instead of milligrams

a milligram table invites false precision. two labradors of the same weight are not the same patient — one is eight and still working, one is thirteen with labs your vet hasn’t seen yet. the pen replaces the table with a fixed mechanical step: one click is 0.05 mL, and the weight sticker chooses how many clicks. same pen, three bands, no syringe math.

that is also the limit. the sticker is a starting point, not a diagnosis. a dog on medication, mid-recovery, or carrying another condition may need a different conversation entirely — which is why the chart says confirm the band with your vet, not self-prescribe from a web page.

what a click carries

each click delivers 0.05 mL, approximately 167 mcg of bpc-157 and 167 mcg of tb-500. the pen holds 10 mg + 10 mg per 3.0 mL and 60 clicks total. mix on day 1; use for 28 days; discard 28 days after mixing even if clicks remain. the 28-day window is the routine, not a race to empty the pen.

miss a day? pick it up at the next dose. don’t double-click. the goal is a routine, not perfection. one pen is $119, and the first three pens carry a 90-day guarantee. the product page is at /pen; this chart also lives at /dosing.

what we don't know

we don’t know a proven dose-response curve in dogs — no completed controlled canine trials exist, so the click chart is a delivery schedule, not an efficacy finding. we don’t know your dog’s interactions, history, or current prescriptions. your vet — after looking — knows more about your dog in one exam than any page knows ever.

what we won't claim

we won’t print a universal mg/kg table and call it medicine. we won’t put numbers on a page to look authoritative. the numbers we do publish are the ones the product can stand behind: 0.05 mL per click, approximately 167 mcg of each peptide, 60 clicks, a 28-day window. the decision about your dog stays with your vet.

the practice frame

the longer version of this — what the pen holds, how the first days go, and how the peel-a-day log card turns a routine into a record — is the starter guide at /guide. print it or save it, and bring it to the appointment.

straight answers

the part your vet owns

your vet owns the plan. we built the part you carry — the pen, the click chart, the log card, the 28-day window. the chart is at /dosing; the hardware is at /pen. that is the whole position.
