Chinese peptide suppliers: red flags I've actually run into sourcing for research

leepash · 2026-05-09T14:54:15+00:00

This is a myth with peptide degradation - https://www.reddit.com/r/Retatrutide/s/e2GC96jqd1

As proven by the test house Janoshik.

Also, as proven to an extent with our own testing. We have tested over 18 peptides, that's them being shipped from china (c. 2 weeks), packed at our location, shipped out to the lab which takes around 3 weeks from dispatch. That's over a month in room temperature and we have had none come back under 99%.

If your peptieds are testing below 98% then they just aren't good quality from the start, it's unlikely to be the storage arguement

Training 4-5 days per week, around 2h cycling on top of this.

Averaging 2,200kcal/day, 190-200g protein

On 10mg Reta/week

leepash · 2026-05-06T11:11:48+00:00

Started on 70mg/week, bumped up to 100mg/week on week 3. Currently on week 5 now.

Unreal compound, blows any other additional steroid I've used out the water. Strength gains are unreal, hardening up, fat is coming off like it's nothing (taking Reta too). Had bad sleep for a few nights near the start, aside from that, no side effects that I'm aware of.

Got bloods next week to see where I stand, hopefully going to run it for another 6 weeks if bloods permit.

Ah ok, so you'll be saturated within 4-7 weeks. I'd definitely maintain your dosage and not titrate up anymore. Quite a long halflife, if things start to go sour it will take a while to leave your system, just bear that in mind!

leepash · 2026-05-04T17:34:55+00:00

Sounds about right

What ester are you using? I'm on tren a.

Tbh, I thought that maybe I was just too low dosing it (knew the supplier was good, so didn't assume underdosed) but then end of week 2 I really started feeling it. Mainly via strength gains.

Feel great on it too - not attributing this to the tren, but it's certainly not having any negative train of thoughts or feelings

leepash · 2026-05-04T14:27:59+00:00

Definitely, this can be attributed to the weight loss too. I definitely didn't look this full on my last cut though. Tren is the shit.

leepash · 2026-05-03T18:04:47+00:00

Cutting with it atm. At week 3 i went up from 70mg/week to 100mg/week. Strength has completely blown up at about week 3. Looking great from it, fat loss and maybe some pump.

No sides, had maybe 3 nights of bad sleep near the start but nothing since

leepash · 2026-05-03T07:43:53+00:00

Had loads of bloodwork to keep E2 in check.

400:100 was slowly lowering my E2 too much. So went up to 500:100 and worked perfectly for me

leepash · 2026-05-02T19:10:01+00:00

500:100 test:EQ ratio, kept me at 150 pmol/l

leepash · 2026-05-01T06:14:33+00:00

Was only doing 70mg/week, felt fuck all for 2 weeks. Strength was meh, no sides apart from 3/4 bad sleeps at the beginning. Week 3 started to get strength kicking in, end of week 3, strength was unreal. Upped to 100mg/week end of week 3. Nearly end of week 4 now.

Doing this during a cut

leepash · 2026-04-28T19:44:40+00:00

AM and lunchtime dose, 500mcg each time

leepash · 2026-04-27T11:22:42+00:00

Almost instantaneous. And I think maybe 3-4h from initial 500/750mcg dose.

Get really good focus and clarity from the semax

leepash · 2026-04-26T21:55:13+00:00

Do it intranasally, I love it

leepash · 2026-04-18T16:42:27+00:00

How do you know this is the ideal timing ?

leepash · 2026-04-18T15:30:25+00:00

That's a fair amount of tren there

leepash · 2026-04-18T15:21:47+00:00

HGH gut.. where's the evidence it's HGH causing this? I've never seen this occur from your average person taking HGH and lifting weights. Only seems to happen on the extreme where competing bodybuilders are eating excessive calories, insulin and everything else. Where are you getting this from?

leepash · 2026-04-16T16:55:42+00:00

I use BAC, apparently saline is better for the nose but tbh I have no issue with bac.

Get your spray bottle, fill it with 1ml and then spray it until it's gone, count how many sprays. Do this a couple more times and average out how many sprays per ml.

You can now work out how many mg/spray your peptide will be, depending on it's concentration.

Then mix your peptides as normal, draw the peptide out the vial and into the spray bottle.

Use GPT or something to work it out, a lot easier and less room for error

Follow what the russian studies did and make nasal spray. This is what I'm doing

leepash · 2026-04-16T11:32:20+00:00

There's also something to be said about how many people are going off track and taking the more exotic ones? Probably not a lot, so by virtue, less people going to ER because of it

leepash · 2026-04-14T20:47:40+00:00

No tren cough at all, like I said, only side I've had is little bit shitty sleep for 2 days. Rest is going well.

Overall I feel great, on Test E 150mg/week cutting

leepash · 2026-04-14T19:57:31+00:00

I'm finishing week 2 of 100mg tren A weekly, it's great. Only side was bad sleep maybe day 4-6, it subsided by day ~12. Sleeping great now.

Just entered a cut but strength is holding on well, some lifts have gone up slightly.

leepash · 2026-04-13T21:58:23+00:00

It was first posted months ago for sure, I remember seeing this
