Bought PT141 and melanotan 1 from them when they had a sale. Tested them out before we chose to buy a kit from a different vendor. They are more expensive than some companies probably because of the packaging. Nice little box with padding holding the vials tightly in place and box lid flips open. From what I remember the COA and lot# matched what was printed on the vial label. Haven't bought more from them though just because of pricing. Looks like they are using Freedom for their testing. Not sure who they used with the vials we bought since they are now long gone. Bought these back before I found this website and became a more informed researcher.

@michaeljeffree - I had the exact same reaction @mikemiranda posted about the injection site reaction and localized fascial irritation around where I pinned. Calling it microtrauma feels accurate because even though it was a subcutaneous shot, it definitely affected the underlying muscle tissue. Within two minutes of injecting, I started getting a radiating pain that stuck around for a while. Even three weeks later, I still have a lingering degree of mild discomfort. The pain has decreased significantly today, but it was prominent enough that I completely abandoned abdominal subq shots. I switched my injection site over to my glutes, and I haven't had a single issue since, but I'm done putting anything in the belly region.

@stevepep is spot on. It's less about what everyone else likes and more about what helps towards the goals you want to achieve. Research your goals and which peptides apply. The vendor listings here are great, but the people in this group are your best research tool. I'm fairly new to peptides myself and I've learned far more than I expected to just by reading threads here. The search function is great for finding specific things that you have questions on too. Best of luck to you on your journey!

@conniebloom You should black out your address and stuff.

@mitchmiller Nexaph product is 99% likely to always come back good. For reference I just got the R48 presale. I got in and ordered on the 18th. It shipped the 23rd, i received the 26th. Mass/Purity and Endo were in within days of me receiving the product. Results were stellar.

wajdinujeidat said: I purchased from this Vendor 2 SS31 50mg. There are some good thing They accept Credit Cards They responded rapidly to my email and my concerns They shipped in 2 days and I received the package with perfect tracking. Package arrived perfectly and well packaged. They accepted to my request to return the package but at the end I didn’t return it because it was worth to return it . My concern was about their COAs. It seems that this Brown BIO… laboratory is a fake one . I found an article about it of someone who looked into it and this laboratory simply doesn’t exist. So I simply put the 2 vials in the freezer and purchased 4 vials from my local trusted but very expensive seller . [image: 1793865526102-img_1075.jpeg]

The labs do there best Iʻm sure but regardless they all need to get on the same page in evaluating our submitted specīmens consistently. Like what is really a filler and what is a contaminent is not always clear or like when there’s presence of alcohol in your sample. Some labs consider it contamination and others don’t. It disturbs me to no end. Also printing additional copies of certifications with different vendor names for the same singular test and specimen- that is WILD and leads customers to be deceived thinking separate tests were taken when only one rest was taken and certificates duplicated. I mean that speaks to trust, accuracy and ultimately to our health and well being. Its like either you exist for your customers or your covering up for the vendors… either way it should be a reasonable expectation and security that each test have ONE certificate issued otherwise that’s just fraud. Super dissapointing and scary- against the whole effort and purpose of what we do- us working so hard to guarentee the safety of we patients… and the labs kind of undermining that. Its not an unreasonable ask or expectation that each specimen tested should have one certificate and not contribute to the fraud of certification which is rampant in this industry without this happening all the time. Sorry so long but I thank you for hearing my opinion. Hope I stuck to the assignment here. Farewell and take care its a dangerous gamble we are forced to deal with to obtain our healthiest selves. Heres to hoping one day the industry as a whole will get their shit together. For the sake of saving lives in reality.

@HockeyRat It happens. I get it but it does happen. I see it a few times a year myself.

@mackhucks we call it lean-maxxing. As long as you hit your protien intake and lift the fat juice is good.

@BeeKind its like checking your own homework. how easy is it to just skip grading your own test?

They have a pretty decent following online. Got some Tirz, Reta and Semax. The tirz was pretty effective in my research. They're tested by Freedom, which I know they're are some folks who are weary of them, but otherwise no issues.
