BPC-157 5 mg vs 10 mg: Which Size Saves You More per Milligram
BPC-157 5 mg vs 10 mg compared by total cost and cost per milligram. Peptide God and Real Peptides pricing broken down with exact arithmetic.
The sticker price on a BPC-157 vial tells you what leaves your account. The price per milligram tells you what you actually paid for the peptide inside. We pulled the current listings from both Peptide God and Real Peptides, divided price by milligrams, and built the tables below so the math sits in one place. For the full seller comparison, see our trusted sellers page.
Price per Milligram Breakdown
| Seller | 5 mg Price | 10 mg Price | 5 mg $/mg | 10 mg $/mg | Savings on 10 mg |
|---|---|---|---|---|---|
| Peptide God | $34.95 | $59.95 | $6.99 | $6.00 | $0.99/mg saved vs 5 mg |
| Real Peptides | Not offered | $43.20 | N/A | $4.32 | N/A (single size only) |
The 10 mg vial wins on cost efficiency for both sellers. At Peptide God, moving from 5 mg to 10 mg drops the per-milligram price by $0.99. Real Peptides does not sell a 5 mg option, but their single 10 mg vial at $4.32 per milligram is the lowest cost per milligram in the comparison.
Peptide God Sizes
5 mg Vial - $34.95
At $34.95 for 5 mg, the per-milligram cost is $6.99. This is the cheapest single vial you can buy from either seller in total dollars, which makes it a reasonable trial purchase. The trade-off is that you pay the highest per-milligram rate of any option listed here. No COA is published on the product page. Product descriptions are blank.
10 mg Vial - $59.95
At $59.95 for 10 mg, the cost drops to $6.00 per milligram. That is a 14% reduction from the 5 mg rate. You get twice the peptide for 71% more money, not 100% more. For buyers planning to use more than 5 mg total, the 10 mg vial is the better deal within the Peptide God catalog. The same documentation gaps apply: no COA, no purity claim, no product description.
Savings Calculation
Buying 10 mg through two 5 mg vials would cost $69.90 ($34.95 x 2). Buying a single 10 mg vial costs $59.95. That is a $9.95 savings on 10 mg of peptide. The per-milligram difference is $0.99 ($6.99 minus $6.00). Over larger quantities, the savings compound. Buying 50 mg through 5 mg vials costs $349.50. Buying 50 mg through 10 mg vials costs $299.75. The gap widens to $49.75.
Real Peptides Sizing
10 mg Only - $43.20
Real Peptides sells BPC-157 in a single size: 10 mg at $43.20 (sale price, marked down from $86.40). That puts the per-milligram cost at $4.32. We confirmed this price on October 9, 2026. Pack discounts apply on top: 5 vials at 5% off, 10 vials at 10% off, 20 or more vials at 20% off. Paying via Bank Pay adds a separate 10% discount. A first-order 40% discount code is available through email signup. Each vial ships with a per-lot COA from Freedom Diagnostics and Kovera, stating HPLC purity of at least 99% and endotoxin levels below 0.1 EU/mg.
Total Cost Scenarios
We calculated what each option costs at common purchase volumes. The Peptide God columns show two paths: buying in 5 mg vials or 10 mg vials. Real Peptides has one path since only the 10 mg vial exists. These figures do not include shipping or bulk discounts.
| Total mg Needed | PG via 5 mg Vials | PG via 10 mg Vials | RP via 10 mg Vials |
|---|---|---|---|
| 10 mg | $69.90 (2 vials) | $59.95 (1 vial) | $43.20 (1 vial) |
| 20 mg | $139.80 (4 vials) | $119.90 (2 vials) | $86.40 (2 vials) |
| 50 mg | $349.50 (10 vials) | $299.75 (5 vials) | $216.00 (5 vials) |
| 100 mg | $699.00 (20 vials) | $599.50 (10 vials) | $432.00 (10 vials) |
At 100 mg, the gap between the most expensive path (Peptide God 5 mg vials, $699.00) and the least expensive (Real Peptides 10 mg vials, $432.00) is $267.00. That is a 38% difference on the same total amount of peptide. Real Peptides' pack pricing would reduce the $432.00 figure further: 10 vials at 10% off brings it to $388.80.
What to Choose
If you want flexibility, start with a 5 mg vial
Peptide God's 5 mg BPC-157 at $34.95 is the smallest commitment in total dollars. It makes sense as a trial purchase when you have not used BPC-157 before and want to test a protocol without spending $43 or more. The per-milligram cost is the highest in this comparison at $6.99, but the total outlay is the lowest. For a detailed look at how the two sellers compare beyond price, see our Peptide God vs Real Peptides comparison.
If you want the lowest cost per milligram from Peptide God, buy the 10 mg
The 10 mg vial at $59.95 costs $6.00 per milligram, saving $0.99/mg compared to the 5 mg vial. Over a 50 mg purchase, that saves $49.75. If you have already decided on Peptide God as your seller and plan to buy more than 5 mg total, the 10 mg vial is the right size.
If published COA documentation matters, consider Real Peptides 10 mg
At $4.32 per milligram, the Real Peptides vial is the cheapest per-milligram option in our comparison. It also comes with per-lot COAs from Freedom Diagnostics and Kovera, HPLC purity stated at 99% or higher, and endotoxin screening below 0.1 EU/mg. The downside: no 5 mg option exists, so the minimum purchase is $43.20.
FAQ - BPC-157 Sizes
Is 10 mg always cheaper per milligram than 5 mg?
At Peptide God, yes. The 5 mg vial costs $6.99/mg and the 10 mg vial costs $6.00/mg, a savings of $0.99 per milligram. Real Peptides only sells a 10 mg vial at $4.32/mg, so the comparison does not apply there. In general, larger vials carry a lower per-milligram rate because the seller spreads fixed costs (vial, cap, labeling) across more product.
Can I buy a 5 mg vial from Real Peptides?
No. As of October 9, 2026, Real Peptides lists BPC-157 in one size only: 10 mg at $43.20. No 5 mg option appears on their site. If you want a smaller quantity, Peptide God is the only seller in our comparison offering a 5 mg vial, priced at $34.95.
How many vials should I buy at once?
That depends on your planned usage and storage capacity. Unreconstituted lyophilized powder stores well frozen. If you are buying from Real Peptides, pack pricing kicks in at 5 vials (5% off), 10 vials (10% off) and 20 vials (20% off). Buying 10 vials at 10% off brings the per-vial cost to $38.88 and the per-milligram cost to $3.89. Peptide God does not offer bulk discounts.
Is the peptide quality different between 5 mg and 10 mg vials?
The vial size refers to the amount of peptide, not the purity or grade. A 5 mg vial and a 10 mg vial from the same seller should contain the same compound at the same purity level. However, neither Peptide God size comes with a published COA, so we cannot confirm purity for either. Real Peptides publishes the same COA documentation for their 10 mg vial regardless of quantity purchased.
What is the price per milligram for each option?
Peptide God 5 mg: $6.99/mg ($34.95 divided by 5). Peptide God 10 mg: $6.00/mg ($59.95 divided by 10). Real Peptides 10 mg: $4.32/mg ($43.20 divided by 10). Real Peptides offers the lowest per-milligram cost. Peptide God's 10 mg is 39% more expensive per milligram than Real Peptides. Peptide God's 5 mg is 62% more expensive per milligram than Real Peptides.
