Anti-Aging topical serum (my new review is here)
Q: Lyophilized / Premium vs. non-lyophilized? See our FAQ
• If sprayer versions are out of stock: Sometimes you can still purchase them as a vial & order the sprayer kit separately (kit comes with everything needed). For reference, Selank as a vial only is here
- If a peptide is completely out of stock, try Biolongevity (below) and use the sprayer kit from Limitless.
*Stock Notes 8/2026:
– Oxytocin & DSIP both back in stock
– N Acetyl Selank Amidate in 30 mg is out of stock. You can purchase the lower priced 20 mg and use 2/3 of the water and have the equivalent strength. Or you can buy it as a vial only (non lyophilized is available) and buy a sprayer kit separately (see blue link above)
– Yes, Premium and Non Lyophilized are both ok (we have used each) see FAQ for more on the topic
– You do not need to add a ‘sterile vial’ to your purchase (it often pops up as a “people also ordered” item)

^For everything they sell, including NAD+ click on upper right menu
Our preferred source for: NAD+ (nasal spray – can be used sublingual), B12 Injections, Glutathione (spray). They also sell: Low Dose Naltrexone and more…
• Be sure to use a TMG supplement when you take NAD+ (to support methylation – mentioned in blog post) the one we buy is only $9 from Life Extension or available at Amazon.
BioLab (UK)
- Discount Code: RESTORE
- They ship to the USA – but the cost is $48. I can no longer recommend buying from the USA, not because of Biolab but because of the US Customs.
- If your credit card declines the international purchase, check our FAQ for help.
- Important Update: As of February 2026, US Customs has been known to delay international packages and sometimes charge duties on certain packages. Both of my last 2 orders were affected and the last one came missing most of it’s contents. (Example: only 1 of the 3 sprayers of oxytocin)
- Link to Store: https://mybiolabshop.com/
Search their site for MANY other products including DSIP Spray (also above), N-Acetyl Selank spray, ARA 290, but know Limitless & Integrative Peptide products often outperform Biolab.
BioLongevity Labs
We haven’t used this brand but it is reputable and others in our group have. I cannot recommend specific products other than you may want to consider what is listed below.
- Discount code: GETWELL
- 15% off, stackable if they have a sale.

Reliable source for buying vials – which you can use as sprays when Limitless is out of stock. They are high quality, third-party tested & made in the USA.
To use as a spray you will need to also order a spray kit from Limitless. The kit comes with: Deionized water (10mL), a syringe, and a nasal spray bottle (that you can alternately use under the tongue)
For the Vials only, here are the links:
* You do not need to add reconstitution solution or Bac water to your cart. You are going to use deionized water for the spray.
Biolongevity also sells certain (not all) Khavinson Bioregulators, useful if Vita Stream is out of stock:
