BeaCapra vs Core Peptides: Which Supplier Fits Your Research?
Core Peptides has established itself as a reliable source for researchers purchasing popular compounds in standard and bulk quantities. BeaCapra takes a different approach, building its model around protocol-based research with subscription delivery and granular purity documentation.
This comparison breaks down the differences that matter for active researchers — from testing methodology to the practical question of how you receive your compounds over a multi-week protocol.
Purity and Quality Assurance
BeaCapra
BeaCapra employs a dual-verification system: every batch is tested via HPLC (High-Performance Liquid Chromatography) for purity and mass spectrometry for identity confirmation. The distinguishing detail is specificity — BeaCapra publishes the exact measured purity percentage for each lot (e.g., 99.3%, 99.6%) rather than rounding to a general "99%+" claim.
All testing is performed by independent, third-party laboratories. COAs include lot numbers, test dates, chromatograms, and lab identification. This documentation is available on each product page before purchase.
Core Peptides
Core Peptides reports a 98%+ purity floor with HPLC testing. Certificates of Analysis are available on request rather than published proactively on product pages. The 98% floor is slightly lower than BeaCapra's 99% standard, though individual batches may test higher.
Verdict
BeaCapra's higher purity floor (99% vs. 98%), dual testing methodology, and proactive COA publishing set a higher standard. Researchers requiring precise batch documentation will find BeaCapra's approach more rigorous.
Pricing Structure
One-Time Purchases
Core Peptides is competitive on one-time pricing, particularly for bulk orders. Their pricing model rewards volume purchases, making them an efficient choice for researchers who know exactly what they need and buy in quantity.
BeaCapra's one-time pricing falls in the mid-to-premium range — comparable to other suppliers that prioritize testing and documentation.
Subscription Pricing
BeaCapra offers 15% savings on individual compound subscriptions and 20% on protocol stacks. For a researcher making monthly purchases, this creates a significant cost advantage over any supplier — including Core Peptides — that lacks a subscription model.
Core Peptides does not offer any subscription or autoship program.
Verdict
For one-time bulk orders, Core Peptides may offer better per-milligram pricing. For ongoing research protocols, BeaCapra's subscription discounts create a more cost-effective model over time.
Product Selection
BeaCapra
24 compounds organized by research category: Healing & Recovery, Anti-Aging & Skin, Growth & Performance, Cognitive Enhancement, Longevity & Cellular Health, and Weight Management. Curated protocol stacks bundle complementary compounds (The Foundation Stack: BPC-157 + TB-500; The Longevity Stack: GHK-Cu + MOTS-C + NAD+; etc.).
Core Peptides
A focused selection emphasizing the most popular research peptides. Strong representation in growth hormone secretagogues and healing compounds. Products are organized by compound name rather than research application.
Verdict
BeaCapra's research-goal navigation and curated stacks add value for researchers building multi-compound protocols. Core Peptides' straightforward catalog works well for researchers who know their compounds and want to order efficiently.
Subscription and Supply Continuity
This represents the most significant operational difference between the two suppliers.
BeaCapra
Full subscribe-and-save program with:
- Automatic delivery every 30, 60, or 90 days
- One-click skip for any upcoming delivery
- Pause options (30, 60, or 90 days)
- Compound swaps at any time
- Cancel anytime with no penalties
- Pre-shipment payment notification (3 days before charge)
Core Peptides
All purchases are one-time transactions. Researchers must manually track their supply and reorder before running out. No autoship, no recurring order option.
Verdict
For researchers running protocols longer than a single order cycle, BeaCapra's subscription eliminates supply gaps and reduces the administrative burden of manual reordering. Core Peptides requires active supply management on the researcher's part.
Shipping and Fulfillment
BeaCapra
Same-day shipping for orders placed before 2 PM EST. Free shipping over $149. Temperature-controlled packaging with insulated mailers and cold packs. Tracking on all orders with guaranteed delivery date based on shipping method selected.
Core Peptides
Standard processing and shipping times. Domestic US shipping available with tracking. Specific same-day cutoff policies and cold-chain documentation are less prominently featured.
Verdict
BeaCapra's documented same-day cutoff and temperature-controlled packaging commitment provides more transparency around fulfillment. Both suppliers ship domestically without reported reliability issues.
Research Tools and Resources
BeaCapra
Interactive reconstitution calculator, embedded research citations on product pages, protocol guidance, and a growing educational blog. Product pages function as research resources — not just storefronts.
Core Peptides
Standard product listings with specifications. Adequate compound information for experienced researchers who already know what they are ordering.
Verdict
BeaCapra's research tools (particularly the reconstitution calculator and embedded citations) add practical value. Core Peptides assumes a higher baseline of researcher knowledge.

Who Should Choose Which?
Choose BeaCapra if: You prioritize 99%+ purity with dual-method verification, want subscription convenience and savings for ongoing protocols, and value research tools like the reconstitution calculator and embedded COAs.
Choose Core Peptides if: You make infrequent bulk purchases, already know your compounds well, and prioritize per-milligram pricing on single large orders over subscription savings.
Frequently Asked Questions
Does Core Peptides offer subscriptions?
No. Core Peptides operates exclusively on a one-time purchase model. BeaCapra is currently the only research peptide supplier offering subscribe-and-save autoship.
Which has higher purity — BeaCapra or Core Peptides?
BeaCapra maintains a 99%+ purity floor with specific per-batch percentages. Core Peptides reports a 98%+ floor. Individual batches from either supplier may exceed these minimums.
Is Core Peptides cheaper than BeaCapra?
On single bulk orders, Core Peptides may offer lower per-milligram pricing. With BeaCapra's subscription discounts (15-20%), BeaCapra becomes more cost-effective for any research spanning multiple order cycles.
Can I get a COA before ordering from Core Peptides?
Core Peptides provides COAs on request. BeaCapra publishes batch-specific COAs directly on each product page, accessible before purchase without contacting customer service.
