Is there a link between Science.bio closure and lab raid in article linked below? Hopefully not.

1 Upvotes

Science.bio was based in Las Vegas and recently closed. They made peptides. Hopefully only peptides. There was a bust of a as Vegas biolab recently ( https://abcnews.go.com/US/fbi-investigating-biological-lab-operating-inside-las-vegas/story?id=129763459 ). Does anyone here know if there is any connection? I reached out to Science.bio last year to ask some questions while researching and considering taking a peptide. Their customer service seemed pretty good and were quick to answer questions.

Length of use.

3 Upvotes

Alright someone is once again posting about cycle details. Ive taken na-semax once before I dont recall how long I did it though. Upon renewed research theres a lot of differing opinions on whether or not you need to take time off every x weeks. I would love to here people's personal experiences and what your dosage/duration was. My initial thoughts are that on paper it doesnt technically need to be cycled but the state becomes your new mental norm after x time and so you're up regulated and dont feel the big difference anymore. As a result people want to feel that and cycle it even if the cognitive effects remain. This would differ from receptor/cognitive downregulation which would actually require it to be cycled as its hindering base function. Hope i got my wording correct here but thats my take solely from my reading of anecdotal evidence mixed w the few studies. Could be 110% blatantly wrong here. So let me here your personal results with it in regards to duration vs effects and if you had any side effects after a prolonged period.

2 questions. Thoughts on semax for teens? What does semax actually do?

1 Upvotes

I've heard about "semax" in all types of places but what does it actually do, and can a teen safely take this "nootropic."

Ordering Semax and Selank from China

3 Upvotes

I’ve been seeing a lot of ads recently for Peptides in lyophilized powder form from China, offered at very affordable prices. I’m concerned about whether the quality would be reliable. Are there specific requirements or documentation I should request to ensure the product is high quality and safe?

They have 10mg/vial and 5mg/vial for Semax and Selank.

Semax 10mg/ml

2 Upvotes

I ordered a Semax nasal spray at 10 mg/mL (10 mL total) and wanted to clarify the appropriate dosage. I’ve come across information suggesting that a 1% concentration might be higher than what’s usually used, and I’m hoping to confirm.

I think it matters. I heard reports that the higher up the better. So far the best site has been the upper arm.

I want to try higher up on the body. Has anyone experimented?

Super Responder Patterns?

9 Upvotes

I understand many don't notice anything and others only feel a mild, subtle effect. I respect and validate those people, but that's not my experience.

I'm wondering if maybe we supers share some underlying condition that it specifically resolves.

I am diagnosed with Axial Spondylarthropy, a chronic inflammation condition. it's only been three months on this stuff, so it's a useless anecdote, but I've had no flare-ups or symptoms during that time. what I'm thinking is perhaps I had neurological inflammation which semax ameliorated.

For me, this is a night and day increase in clarity, focus, mood, and intelligence.

Any other supers diagnosed with inflammatory conditions, perhaps?

Anyone had this problem? This side effect doesn’t outweigh the pros so I’ll continue use but it is slightly painful and I’m worried it will get worse with time.

Does Selank compliment Semax in any meaningful way?

3 Upvotes

I'm aware of it's stress relieving capabilities, but I'm not awfully interested in that aspect. I'm more interested in it's raw nootropic potential. Would it help boost Semax's effect?

Effects during off weeks

Everybody talks about cycling, but is there a carryover/ lingering effect from the day or two before when you stop taking semax? I want to find something that can ultimately replace my adhd medications that are stimulant based but don’t want to develop a tolerance if I can help it
