Healed my tendinopathy !
"I started bpc-157, 7 days ago for quad tendinopathy I had for years. A ton of stretches, exercices with elastic bands, eccentric loads and so on with minimum results. I was done with that. After 7 days tendinopathy is gone like no difference between both knees. My wife had a tennis elbow for months. Same within a week pain is gone.

Everything you need in one box
"I’d ordered from two other sites before and always had to hunt down sterile water separately - super annoying. OptimaSciences proposes it with every order, which made everything much smoother. Shipping was fast so I could start immediately. I’ll definitely order again.
Jerome B.
Smooth experience from start to finish
"Honestly impressed. I ordered Monday and it arrived by Thursday with tracking right away. The site and checkout were quick and easy, and the package was discreet and well-protected. Exactly the hassle-free service I wanted. I'm already planning my next order."
Emma F.
Great customer service and fast shipping
"I had a few questions before ordering as it was my first time buying Peptides and they replied within hours with super helpful answers. Shipping was faster than expected. Everything arrived as described in a discreet packaging. I’m ordering again and already recommended them to two friends."
Kriss H.
Impressive results with Retatrutide
"My wife started Retatrutide about 6 months ago and the results have been remarkable. She went from 170 lbs to 125 lbs with no side effects and more energy than she’s had in years. OptimaSciences' quality has been consistent across multiple orders, and we’re both really happy with the outcome."

Yes, research peptides are legal to purchase in Canada when sold for research purposes. Our products are available as research chemicals without requiring a prescription for laboratory use. All our peptides are clearly labeled "For Research Use Only" to comply with Health Canada regulations.

Yes! Our auto-ship subscription service lets you receive your peptides on your preferred schedule (monthly, bi-monthly, etc.) with these benefits:

  • Automatic discount on every subscription order
  • Free shipping on qualifying orders
  • Reminder before each shipment
  • Cancel, pause, or modify anytime – no commitments or fees

Never run out of your research peptides while saving money on every order.

Our peptides arrive as lyophilized (freeze-dried) powder in sterile vials. The standard protocol involves:

  1. Reconstitution: Mix the powder with bacteriostatic water (whe offer Bacteriostatic water with all our orders) 
  2. Administration: Please do your own research for this step, as our products are for research use only and we cannot provide further information.

We provide basic reconstitution and storage guidelines with all products. Our support team can answer general research questions, though we cannot provide medical advice.

Proper storage maintains peptide stability and potency:

Before reconstitution (powder form):

  • Store in a cool, dry place away from direct light
  • Room temperature acceptable short-term
  • Refrigeration (2-8°C) recommended for long-term storage

After reconstitution (liquid form):

  • Must be refrigerated at all times (2-8°C)
  • Use within recommended timeframe (typically 2-4 weeks, varies by peptide)
  • Keep in sterile vial to prevent contamination
  • Do not freeze unless specifically instructed

Following these guidelines ensures your peptides remain stable and effective throughout your protocol.

Absolutely. Quality is our top priority. Every batch undergoes third-party laboratory testing to verify identity and purity. Our peptides typically exceed 99% purity as confirmed by HPLC and mass spectrometry analysis. 

When used properly in appropriate settings, many peptides have demonstrated very favorable safety profiles. Some peptide therapies are even FDA-approved for specific medical conditions. 

However, peptides are potent bioactive compounds that require responsible handling.

Potential considerations include injection-site reactions, headaches, or hormonal effects depending on the specific peptide and dosage. Quality matters significantly.

Our commitment: Lab-grade purity and third-party testing ensure you receive the highest quality research peptides available.

Yes, peptide stacking is common in protocols. Multiple peptides can target different pathways simultaneously. For example, BPC-157 and TB-500 are frequently combined for tissue repair research (sometimes called the "Wolverine Stack") due to their complementary mechanisms.

Important considerations when stacking:

  • Research each peptide's properties thoroughly
  • Peptides should always been administered separately
  • Start with conservative amounts
  • Monitor for any adverse interactions
  • Consult with knowledgeable professionals when designing research protocols

Stacking can enhance outcomes but requires careful planning and documentation.

We offer fast domestic shipping across Canada with delivery typically within 2-4 business days to most addresses. Because we produce and ship from within Canada, you avoid customs delays and international hassles.

Discreet packaging: All orders arrive in plain, unbranded packaging with no external labels indicating contents. Temperature-sensitive products include appropriate cold packs or insulation.
